San Diego Sheriff's Deputies are on alert in Del Mar, making sure everyone stays safe during KAABOO, a music and arts festival.

For many visitors, security during the large festival is a concern. 

But some nearby residents are more concerned about what happens outside the gates. 

Greg Rolfsmeyer has lived just steps away from the Del Mar Fairgrounds for the past 25 years.

"There were years when they had motorcycle races down there, that was terrible," Rolfsmeyer said.

He said the noise from the live music isn't too big of a deal for him, but what is a big deal for him are the cars lining every street. 

When visitors come back to their cars after a night of fun, they are not always the most considerate.

"They have a tendency to still be partying and kind of loud and sometimes they leave beer cans and bottles in the yard," he said.

Other Del Mar residents, like Andrew Berlin, says events like these only make Del Mar an even better place to live. 

He has decided to embrace the event along with many of his neighbors, setting up shop in their backyard.

"Good music, a little bit late, what's the harm," Berlin said. "It's part of being a local and living here a while and knowing what’s what."

DJs perform until the early morning hours. Organizers tell NBC 7 those shows are in tents to help cut down on the noise impact to nearby residents.

KAABOO runs Friday, Sept. 16 to Sunday, Sept. 18.

Cal Fire crews are working to put out a small six acre brush fire in Julian. 

The fire broke out late Sunday morning near Harrison Park Road and Highway 79, Cal Fire officials said. 

It was first reported at two to three acres, but has since grown. 

Crews are "making good progress," Cal Fire tweeted. 

It is unclear how fast the fire is moving.

No other information was immediately available.

Trolley service has resumed after a suspicious device temporarily halted the green line at Qualcomm Stadium. 

Authorities began investigating the suspicious item near the stadium trolley station at approximately 1:45 p.m. Sunday, San Diego Police (SDPD) said. 

"The object was very close to the platform. Under the abundance of caution, we called out Metro Arson Strike Team to come out to make sure that object that was very suspicious in nature did not pose a threat to anyone that would be leaving the Chargers game," said Chief of San Diego Police, Shelley Zimmerman.

Zimmerman would not specify what type of item they found, but did say it was clear the item did not fit in and was not supposed to be there. 

“We ask the public that if they see something out of the ordinary, and I can tell you this was definitely out of the ordinary, to make sure to say something to police,” Zimmerman said.

During their investigation, authorities halted green line trolley service between Fenton Parkway and Grantville. Trolley service has since resumed. 

At the time, the San Diego Chargers were approximately an hour into their home opener against the Jacksonville Jaguars. 

Police say fans inside the stadium were considered safe during the investigation. 

“I think we're all very thankful especially in light of what's been going on in the world in these last few days," Zimmerman said. "Public safety is always going to take precedence in everything we do."

No other information was immediately available.

At least one fight erupted Saturday night at the KAABOO Musical Festival in Del Mar when festivalgoers became frustrated trying to get into a popular event in a small venue, according to witnesses and officials. 

Tempers flared Saturday night as people who had been waiting for two hours to see Steve Aoki perform at the ENCORE stage became angry when the venue reached capacity.  

"When you get a high personality like Steve Aoki and tell people you're going to sell out, while you have 10,000 people scheduled to go see him into an arena that only holds like, 4,000 people, it's not the best planning," said festivalgoer David Lopez, a Chula Vista resident. 

He spent $280 on tickets for the 3-day festival and went to see Aerosmith last night. Lopez said he eventually transitioned to go see Aoki. 

But when he went to the venue, he noticed it quickly became unruly. 

"It turned into a big chaos riot," Lopez recalled. "People throwing stuff, fights breaking out and cops tackling people with pepper spray and tasers." 

Lopz said he was surprised, as he expected the event, now in its second year, to be mellow. 

A San Diego County Sheriff's Lieutenant told NBC 7 San Diego the venue filled up as people from other venues were trying to leave, and the crowd became unruly. There were several fights, the Lieutenant said. 

He did not have a specific number, but said between one and four people were arrested.

A KAABOO spokesperson siad they understood some people were disappointed they could not get into the venue, but safety comes first. 

"KAABOO and the Del Mar Fairgrounds apologize to those who were unable to enjoy ENCORE last night. The venue was at capacity. For the safety of our guests, security and the Sheriff’s Department dispersed any unruly crowds. There were no injuries. All experiences are on schedule as planned for today. We are very much looking forward to seeing you," a KAABOO spokesperson said in a statement.

Sheriff's officials formed a skirmish line and people eventually dispersed into the parking lot to end the incident.

Lopez said it took anywhere from two to three hours to get out of the parking lot, as well. 

"The parking management was just horrible," he said. "You have people waiting in line two to three hours to get out of a dirt area of Del Mar."

No one was injured, Sheriff's officials said. 

No other information was immediately available. 

Authorities are looking for a 28-year-old naturalized Afghanistan citizen in connection with the bombing in Manhattan's Chelsea Saturday that injured 29 people, and multiple senior law enforcement officials tell NBC News they also suspect the man was involved in pipe bombs going off in Seaside Park and Elizabeth, New Jersey.

Ahmad Rahami, whose last known address is Elizabeth, is about 5 feet 6 inches tall and weighs about 200 pounds. Rahami has brown hair and eyes and facial hair; authorities say he should be considered armed and dangerous. An emergency alert was sent to all smartphones in the area urging anyone who sees him to call 911. 

[[393953141, C]]

"We do not yet know if this was a lone wolf or if it was something that involved other individuals," Mayor Bill de Blasio said in an MSNBC interview.

Five people believed to be relatives or associates of Rahami were taken into custody Saturday during a traffic stop on the Verrazano Bridge. No one has been charged; the traffic stop came as authorities pursued a "promising lead" into surveillance video obtained from two sites in Manhattan where explosive devices were found -- one on 23rd Street and one on 27th Street. 

Rahami is believed to be the man seen on surveillance video at two locations where the explosive devices were recovered.

One video shows a man putting an object in a dumpster near 23rd Street and Sixth Avenue, followed by an explosion some time later. Another video from 27th Street shows a man leave a piece of luggage on the sidewalk; that piece of luggage contained a bag with a pressure cooker inside. The cooker had a cellphone attached and wires protruding. It was taken to a Bronx firing range.

No one was hurt in the two New Jersey cases. A robot trying to disarm one of five pipe bombs found in a trash can near an NJ Transit station in Elizabeth inadvertently detonated the device, causing an explosion. On Saturday, a pipe bomb went off in a trash can along a Marine race route. Officials said they thought the bomb had been timed to detonate as participants were running by, but the race started late.

Old-fashioned flip phones were found on the devices in Manhattan and in Seaside Park, law enforcement officials close to the investigation told NBC 4 New York. The investigation into the devices found in Elizabeth Monday was ongoing.

The series of incidents put the entire tri-state area on edge. Early Monday morning Rutgers University urged people to avoid a New Brunswick parking garage while a suspicious package was investigated. Calls to police about suspicious packages skyrocketed amid heightened tensions. 

The Chelsea explosion left many rattled in a city that had marked the 15th anniversary of the 9/11 attacks only a week earlier and that was schedule to hold a United Nations meeting Monday to address the refugee crisis in Syria. 

Witnesses described a deafening blast that shattered storefront windows and injured bystanders with shrapnel in the mostly residential neighborhood on the city's west side.

[[393947381, C]]

Former New York Police Commissioner Bill Bratton, who stepped down just last week, said Monday morning this was probably the first successful terrorist attack in the city since 9/11. 

Mayor de Blasio said there is “no specific and credible threat against New York City at this point in time from any terror organization,” but urged vigilance.

Police have ruled out a connection to the blast in Central Park in July that blew off a teen's foot. Right now police are trying to figure out the motive behind the attack. 

“We do not know the motivation. We do not know the nature of it. That's what we have to do more work on,” de Blasio said Sunday.

Cuomo had said Sunday that there was no evidence to suggest that the bombing was related to international terrorism, but he appeared to walk that back Monday. 

"Today's information suggests it may be foreign related, but we'll see where it goes," he said.

On Sunday, the governor deployed nearly 1,000 additional State Police and National Guard troops across the city to guard transit stations and area airports as a precaution. 

The White House said President Obama was briefed throughout the night and early Monday on the investigation into bombs found in New York City and New Jersey. Spokesman Josh Earnest said Obama will comment publicly later Monday.

One of five devices found in a bag near an Elizabeth, New Jersey, train station exploded early Monday as a bomb squad robot was trying to disarm it, and just hours later heavily armed FBI agents were seen in the city as authorities grew more concerned that there may be an active terror cell in the tri-state area. 

The news of the suspicious bag at the Elizabeth station was first reported late Sunday, around the same time that the FBI said it had taken five people into custody for questioning in connection with Saturday's bombing in Manhattan's Chelsea neighborhood after a traffic stop on the Verrazano Bridge. 

The agency said that the five individuals who were taken into custody are from Elizabeth, and law enforcement sources familiar with the investigation tell NBC 4 New York they are believed to be relatives or associates of 28-year-old Ahmad Khan Rahami, the suspect sought in connection with the Chelsea bombings as well as the pipe bomb in Elizabeth and another in Seaside Park, New Jersey, over the weekend. No charges have been filed. 

An FBI wanted poster for Rahami said his last known address was in Elizabeth and warned that he could be armed and dangerous. 

There was law enforcement activity at an address on Elmora Avenue in Elizabeth at 6 a.m. Monday. Officials familiar with the investigation said that it's connected to the investigation at the Elizabeth NJ Transit station. Heavily armed FBI agents in camouflage were focusing on a residence above "First American Fried Chicken." 

Police and the FBI had responded earlier to the Elizabeth NJ Transit station after two homeless men found a suspicious bag there around 8:30 p.m. Sunday; devices in the bag were later determined to be explosive. The bag was in a trash can next to a trestle near the station, Elizabeth Mayor Chris Bollwage said.

After the bag was discovered, all New Jersey-bound Amtrak trains were held at New York Penn Station in midtown, hampering travel on the busy North East Corridor. NJ Transit service was also suspended between Newark Liberty Airport and Elizabeth, affecting the Northeast and New Jersey Coast lines. Amtrak and NJ Transit serive had resumed with delays by 6 a.m. 

Around 1 a.m. Monday, an explosion was heard near the train station in Elizabeth. A robot named "Jinx" was being used to dismantle the bomb at the time of the powerful blast and inadvertently detonated the device. 

Mayor Bollwage said that five separate pipe bomb devices were found inside the bag and that those devices were pulled from the bag and separated so that they could be inspected. As the robot was "cutting wires" on the first device, it went off, startling everyone at the scene. No one was injured. Bollwage said it "could have hurt a lot of people." 

Authorities were reassessing how to handle the other four devices after the first one exploded. 

The devices in Elizabeth apparently looked similar to what detonated in Seaside Park, New Jersey, on Saturday morning ahead of a Marine race. No one was injured in the Seaside Park explosion. 

Two bar patrons found the bag containing the devices in a trash can near train tracks. They looked inside and found pipes and wires. They then called authorities.

Bollwage said that the men are being questioned at police headquarters but are not suspected of building or planting the device. 

"We do not believe they were involved. We believe they did the right thing," Bollwage said. 

Lightning and thunder awakened San Diegans early Monday and sparked several fires.

In North Park, resident Graden Tonna shot out of bed when she heard what she described as an explosion.

“It sounded like the sky was ripping open outside of our window,” Tonna said.

Tonna lives near the intersection of Dwight and 32nd Street where a utility pole burst into flames at approximately 3 a.m.

One couple who live on the corner told NBC 7 they had been listening to the thunder when they heard a blast right outside their window.

They came out to see the pole on fire. They immediately called 911.

San Diego Police and San Diego Fire-Rescue crews arrived. The street was quickly blocked off.

San Diego Gas & Electric crews used a fire extinguisher to put out the fire.

In Valencia Park, lightning struck a palm tree and sparked a fire in the middle of the tree's trunk, according to SDFD officials.

Even as a trendy Miami neighborhood has been declared Zika-free, the mosquitoes that transmit the virus can continue to survive over the next few months across the southeast United States from Florida to Texas, research shows.

The potential for an abundant population of the Aedes aegypti mosquito remains moderate or even high through November in the southernmost cities in the country, according to a study, “On the seasonal occurrence and abundance of the Zika virus vector mosquito Aedes aegypti in the contiguous United States.”

Florida with its hot, humid weather is particularly vulnerable. In November, the threat will be high in and around Miami and moderate in Jacksonville, Orlando and Tampa, in New Orleans and in Houston and Brownsville, Texas.

Only in December will the risk decrease enough so that Miami alone will have a moderate potential for a significant supply of mosquitoes. Elsewhere in Florida, Louisiana and Texas there will still be some potential, though a low one.

Winter weather will be too cold for the mosquitoes elsewhere.

“When a mosquito bites someone and gets a virus it needs a week or two depending on temperature to actually incubate a virus — for it to move from its mid gut up to its salivary glands,” said the study’s lead author, Andrew Monaghan, a scientist at the National Center for Atmospheric Research in Boulder, Colorado. “If you’re in cooler areas, not only is that slower but mosquitoes often won’t survive it long enough to go through that extrinsic incubation period.”

The study, which looked at 50 cities within the range of Aedes aegypti, was published in March before locally transmitted cases of Zika were discovered in Florida — 70 cases in all, many in the Wynwood arts neighborhood of Miami and across Biscayne Bay in Miami Beach. Authorities in Florida say that they have found the virus in mosquitoes trapped in a 1.5-square-mile area of Miami Beach, a first for the continental United States.

On Monday, officials declared the first Zika outbreak on the continental United States to be over. No new cases of Zika have been found in Wynwood for 45 days, which represent three full incubation periods for the virus. However more cases were found in Miami Beach last week.

Monaghan and the study’s other authors had warned that the prevalence of Aedes aegypti would likely increase as the weather got warmer.

From New York to LA
Researchers found that conditions in the United States are mostly unsuitable for the mosquitoes from December through March, except in southern Florida and south Texas, where the potential for an abundant population is low to moderate.

In the peak summer months, July through September, the mosquito can thrive in all 50 cities -- as far north as New York City along the East Coast and as far west as Los Angeles across the southern portion of the country, according to computer simulations run by researchers at the National Center for Atmospheric Research and the NASA Marshall Space Flight Center. The mosquitoes are most abundant in the Southeast, particularly southern Florida, and south Texas where locally acquired cases of Aedes-transmitted viruses have been reported previously. Higher poverty rates in cities along the U.S.-Mexico border may result in increased exposure to the mosquito.

But Zika is unlikely to spread widely in the United States as it has done in the Caribbean and Latin America, experts say. That’s because so many Americans live in air-conditioned homes and work in air-conditioned offices.

Zika was first identified in 1947 in Uganda, and has moved through tropical regions of the world over the past 10 years, according to experts.

The role of climate change
One question has been the role climate change is playing in the widespread Zika epidemic. Sharyn Stein, a climate scientist at the Environmental Defense Fund, said that though many factors can affect the spread of a disease like Zika, mosquito seasons are lasting longer.

“In some places it’s lasted three or four weeks longer than usual and so people will be exposed to mosquitoes carrying Zika for a lot longer period of time,” she said.

But how a warmer warm will influence the spread of the virus is not known, she said.

Much is not known about the virus and the latest mystery is how a dying man in Utah infected his son. Doctors in Utah warned that blood and other body fluids of people who are severely ill might be infectious.

Although most people with Zika have more mild symptoms, the disease can cause microcephaly in babies — and the accompanying devastating birth defects.

“While there is much we still don’t know about the dynamics of Zika virus transmission, understanding where the Aedes aegypti mosquito can survive in the U.S. and how its abundance fluctuates seasonally may help guide mosquito control efforts and public health preparedness,” Monaghan said when the study was released.

A battle over funding
President Obama has asked for $1.9 billion in emergency funding; Congress countered with $1.1 billion but has not passed the legislation. Republicans tried to prevent money from going to clinics in Puerto Rico run by ProFamilias, a Planned Parenthood partner, as part of their approval -- a provision Democrats have refused to agree to. This week, 77 mayors, including those of Miami Beach, Los Angeles, New York City, Chicago, Philadelphia and Boston, wrote to the Congressional leadership urging that Congress work together.

“Congress’ persistent inaction has forced the National Institutes of Health (NIH) to use more than $10 million of its funding for cancer and heart disease research for Zika,” the mayors wrote. “In total, $670 million has been diverted from other health priorities to fund Zika research. In addition, the CDC estimates that it will run out of funding to combat Zika at the end of this month, just as mosquito season reaches its peak.”

The CDC reports 20,870 cases of the Zika virus in the United States and its territories —  3,176 in the states and the District of Columbia, most of those brought by travelers, and 17,694 in the territories. So far, 1,887 pregnant women have tested positive for the virus, 731 in the states and 1,156 in the territories. Twenty-five babies are affected, according to the CDC's Dr. Anne Schuchat.  

“The critical resources that President Obama has requested would help prevent the spread of the virus by allowing local governments to work in cooperation with the CDC and the NIH to enhance mosquito control, conduct tests, and deploy a critical Zika vaccine,” they wrote.

Florida Gov. Rick Scott has singled out the Obama administration and Democrats for blame.

A long history in the US
The Aedes aegypti mosquito, which also spreads viruses for yellow fever, dengue and chikungunya, has been in the United States since at least the mid-1600s, when the first cases of yellow fever were documented. It transmitted yellow fever up the northeastern seaboard as far as New York and dengue as early as 1780 in Pennsylvania.

“Conditions were more suitable for Aedes aegypti in the northeastern U.S. a couple of hundred years ago when piped water access was lower, sanitation was much worse,” Monaghan said. “And human exposure was higher as well. People weren’t living in air-conditioned, screened environments. The likelihood of them coming into contact with this mosquito was much higher.”

The mosquito was nearly eradicated in the United States in the first half of the 20th century but has since rebounded, though today its range has contracted to the southern tier and up the eastern seaboard.

Monaghan said he and his colleagues are working to improve their modeling so that public health and mosquito control officials could provide early warnings — not just of when the Aedes aegypti populations are elevated but also what might influence the transmission of the virus and other projections.

They noted that northern cities could become more vulnerable if a related species of mosquito, Aedes albopictus, starts to carry the virus. Aedes albopictus is more tolerant of the cold.

Amal Clooney is taking up the fight of Iraq's Yazidi community, driven from their homes by ISIS in a campaign the United Nations and U.S. State Department have called genocide, NBC News reported.

The renowned human rights lawyer, who is married to George Clooney, recently told a group of Yazidi refugees in Greece that "the international community should be ashamed that they haven't done more" to help them.

Along with a 23-year-old survivor of three months in ISIS captivity, Clooney is trying to persuade the international community to begin collecting evidence so the members of ISIS who have attacked Yazidis can be prosecuted in international court.

"Victims have all said they actually want their day in court," Clooney told NBC News in an exclusive interview. "It's not going to be easy, but we're working on multiple fronts."

EpiPens are like an insurance policy for those who suffer from life threatening allergies; to do without it is like a daily game of Russian roulette. 

With EpiPens costing some patients more than $600, it may not be a surprise that people are looking for a way around the high prices. 

“My whole life is carrying the EpiPen so when the cost goes up, it automatically affects our family,” Jennifer Savant said. 

Savant’s three children are severely allergic to almost everything. Most family meals are made at home but even that is sometimes risky.

“When we go anywhere they usually have some kind of reaction,” Savant said. 

Savant’s children are ages five, seven and 11 years old. According to the most recent San Diego County Health data, Anaphylaxis cases have increased the greatest among 10-14 year olds with an increase of up to 783%. 

Overall, emergency room visits for anaphylaxis increased by 265% from 2006 to 2014, according to the county health data. 

EpiPens are prescribed to patients whose allergies are so severe they could experience Anaphylactic Shock, a whole-body allergic reaction that can kill in just minutes. 

EpiPen’s price climb started in 2011. The two-pen pack went from around $150 to a little over $600 in May. 

Most EpiPens have an expiration date of one year. With the price climbing, NBC 7 Investigates found some seem willing to put that expiration date to the test in an online market for nearly expired EpiPens. 

On Craiglist, one pair of EpiPens expiring in April 2017 was being sold on Craigslist for $50. Another EpiPen pack from San Jacinto expires next month but can be bought for just one dollar. The seller told NBC 7 Investigates he's sympathetic to those who can't afford it. 

Diana Zuckerman, a doctor with the National Center for Health Research, says such transactions usually go under the radar but buyers should be beware. 

“We don’t know what’s going on with those EpiPens,” Zuckerman said. “Are they real? Do they actually have epinephrine, the drug they are supposed to have? Is it the right dosage?” 

Savant says she'll keep prescriptions for up to two months past expiration, sometimes using the pens for practice, other times, it’s just extra peace of mind. 

“It would be better to have an old EpiPen then have none at all but that shouldn't be the choice,” Dr. Zuckerman said. 

Mylan, the company that distributes EpiPen, has recently defended it’s pricing for EpiPens. The company is now offering coupons and announced plans to offer a generic version for 50% less. 

“This isn’t an EpiPen issue; this isn’t a Mylan issue; this is a healthcare issue,” Mylan CEO Heather Bresch said in an August 25th interview with CNBC. “The irony is that the system incentivizes higher prices.” 

NBC 7 Investigates emailed and phoned Mylan for a response to this story but have yet to hear back from the company. 

Last week, a group of legislators introduced the FAIR drug pricing act, saying it is the first step in addressing skyrocketing prescription drug prices. The bill would require transparency and accountability from pharmaceutical corporations that plan to increase drug prices. 

NBC 7 Investigates has learned some local schools have depended on Mylan for years for stocking EpiPens on their campuses in case of a student emergency.

Lawmakers are asking the Federal Trade Commission to investigate a program local school districts use to acquire EpiPens for students, alleging violation of anti-trust laws. 

The program, EpiPen4Schools, benefits school districts across the nation, including schools here in San Diego County, by providing EpiPens to schools to be used in case of emergencies. 

The EpiPen contains epinephrine, a drug used to treat someone experiencing a life-threatening allergic reaction or anaphylaxis. 

Dr. Howard Taras with the University of California San Diego writes prescriptions locally for the EpiPen4Schools program and said he has written prescriptions for 25 school districts in San Diego County. 

“The purpose of these standing orders is so that school sites have these injectors around so that staff can respond to severe allergic reactions,” Dr. Taras told NBC 7 Investigates by email. “My prescribed standing orders are primarily for students without previously known risk for allergic reactions.” 

In 2014, the California Governor signed a law that requires schools to be supplied and trained with epinephrine auto-injectors, to be prepared in the event of a student having an allergic emergency with no previous knowledge of the allergy.

According to Taras, school districts are worried Mylan, the company that purchased and took over production of EpiPens in 2007, could remove the free epinephrine program making it very expensive for the schools to comply with the 2014 California law. 

Analysts say Mylan began to raise the price for a two pack of EpiPens by over 400% since 2011, leaving some patients having to pay over $600 out-of-pocket for the medication. 

Mylan’s CEO Heather Bresch, in an interview with CNBC’s “Squawk Box” on August 25 said Mylan is not responsible for the rise in price. 

“This isn’t an EpiPen issue; this isn’t a Mylan issue; this is a healthcare issue,” Bresch said. “The irony is that the system incentivizes higher prices.” 

In August, 2012, Mylan launched the EpiPen4Schools program in an effort to provide the medication to schools at no cost. Since then, Mylan says it has distributed more than 700,000 pens to approximately half of all U.S. schools.

Now, the requirement these schools have to agree to in order participate in the program is being called into question. 

Section six (vi) of the Mylan certification form for schools and school districts states, “the school hereby certifies that it will not in the next twelve (12) months purchase any products that are competitive products to EpiPen Auto-Injectors”

To see the application being questioned, click here.

Earlier this month, U.S. Senators Richard Blumenthal and Amy Klobuchar said this requirement violates antitrust laws and should be considered as “exclusionary practices to hinder its competitors and maintain its monopoly position in the market.” 

The FTC has been asked to investigate what effect, if any, this requirement had on schools and competing companies.

NBC 7 Investigates reached out to Mylan, asking if the company had any comment in regards to lawmakers asking the FTC to investigate antitrust claims. While the company did not directly respond to the inquiry, Mylan noted the program has always and will continue to adhere to all applicable laws and regulations.

Mylan’s CEO Heather Bresch told CNBC’s “Squawk Box” the company is responsible for passing legislation in 48 states, allowing undesignated EpiPens to be in schools. 

“In one year alone, 2015, there were 1,000 anaphylactic events in schools and 25% of the time, people had no idea they had a known allergy,” Bresch told CNBC. 

In San Diego County, children having to go to the emergency room for anaphylaxis increased greatly from 2006 to 2014 according to the most recent data from the San Diego County Health Department. 

According to the Health Department data, there was a 265% increase in the number of emergency room visits where anaphylactic shock was the diagnosis.  The data says that increase was highest among 10 to 14 year olds, with a 783% increase and 15 to 19 year olds with a 600% increase in that time period.

NBC 7 Investigates reached out to every school district in San Diego County but only a handful responded to our request. 

A representative from San Diego Unified School District told NBC 7 Investigates, in 2012-2013 the district began providing EpiPens to all schools, approximately 180 sites, through the EpiPen4Schools program.

Because the applications for the EpiPen4Schools program are submitted online, an SDUSD representative said it did not have a copy of the application SDUSD submitted for the program.

Taking another step in the fight against climate change, Gov. Jerry Brown signed a bill with new restrictions on super pollutants Monday in Long Beach.

Super pollutants like black carbon and methane trap more heat than carbon dioxide but stay in the atmosphere for a shorter time. Reducing super pollutant levels can have a more immediate impact on climate change, he said during the signing event in Long Beach.

"Cutting black carbon and other super pollutants is the critical next step in our program to combat climate change," Brown said. "This bill curbs dangerous pollutants and thereby protects public health and slows climate change."

The new legislation establishes the country’s toughest restrictions on these pollutants. The law mandates a 50 percent reduction in black carbon and 40 percent reduction in methane and hydrofluorocarbon from 2013 levels by 2030.

The pollutants are generated by by sources including waste-disposal, petroleum-based fuel, agriculture and synthetic gases used in refrigeration, air conditioning and aerosol products.

The National Federation of Independent Business criticized the legislation, with the organization's state director Tom Scott saying it creates an inconsistent policy that will "further increase the cost of doing business in California," particularly for the agricultural industry.

The mandated reductions represent "a direct assault on California's dairy industry and will hurt manufacturing by creating an arbitrary limit on natural gases which dissipate quickly," he said.

The signing comes just weeks after Brown extended by 10 years another climate change law which aims to reduce greenhouse gas emissions. The expanded law set a new target for 2030.

The bill signing also coincides with the start of Climate Week in New York City and the first meeting of the United Nations General Assembly since the Climate Change Conference in Paris last December.

Tijuana Police have arrested a man who allegedly admitted to dumping his girlfriend's dead baby in an empty lot in Tijuana.

Luis Espinoza was arrested Monday morning in Tijuana, a source with Procuraduría General de Justicia del Estado de México (PGE) told NBC 7. Specific charges are unknown at this point.

Seven-month old Elliot Villalobos was found dead on Sept. 2 in the Lomas de la Presa neighborhood, about 12 miles south of the San Ysidro Port of Entry. The baby’s mother, 20-year-old Jasmine Villalobos, led Chula Vista police to the body after officers found her living with her boyfriend, Espinoza in San Diego.

The FBI was involved in the investigation into the death of Elliot, a U.S. citizen.

Law enforcement officials in San Diego and in Tijuana believe the baby was killed in Mexico. But, the FBI was considering whether it can bring charges based on a federal statute that says a U.S. citizen cannot kill another U.S. citizen in foreign lands.

Villalobos’ relatives had reported her missing on August 31, concerned after they did not hear from her since the end of June.

According to authorities, Villalobos and Espinoza told officers that baby Elliot had suffered a fatal fall. They didn’t know what to do so they wrapped up the baby in blankets and left him in the empty lot in Tijuana.

Espinoza is the not the baby’s biological father.

After unruly crowds prompted a police response at the KAABOO Musical Festival in Del Mar this weekend, some festival goers say they plan to stay away from the festival next year. 

As many as four people were arrested by San Diego County Sheriff’s Deputies Saturday when at least one fight erupted between ticket holders turned away from seeing rapper Ludacris and DJ Steve Aoki at the ENCORE stage.

"I thought I was going to get trampled to death," one festivalgoer wrote on Facebook. 

"...Realizing how unsafe this festival was, we left early ... Never going back to KAABOO," another wrote on Facebook.

A San Diego County Sheriff's Lieutenant told NBC 7 San Diego the venue filled up as people from other venues were trying to leave, and the crowd became unruly. There were several fights, the Lieutenant said. 

A KAABOO spokesperson siad they understood some people were disappointed they could not get into the venue, but the matter was an issue of safety. The spokesperson said they do not release specific numbers for venues. 

Though Tim Fennell, CEO/General Manager of the Del mar Fairgrounds, where the festival was held, says more than 75,000 people attended the three day festival.

Fennell says there’s a simple fix to the issue that sparked the chaos Saturday night.

“You want to make sure the programming is correct, so traffic flow is better. So from a programming standpoint, we'll sit with KAABOO and work out what shows are on what stage. When do stages let out, so you can increase traffic flow," said Fennell.

Despite the incident, officials say no one was injured. Sheriff's officials formed a skirmish line and people eventually dispersed into the parking lot to end the incident.

However, festivalgoer David Lopez, a Chula Vista resident, said the incident was a beyond-hectic experience. 

"It turned into a big chaos riot," Lopez recalled. "People throwing stuff, fights breaking out and cops tackling people with pepper spray and tasers." 

Fennell says they are in the process of reviewing complaints left on a hotline setup to field concerns.

A member of the City Manager's office says they will get reports from the Fairgrounds and relay them to City Council members, most likely at their October meeting.

“The most we can do is if we perceive there's a gap in security, we can point it out and say hey next time maybe you want to do it better. But I suspect they did it right,” said Del Mar City Councilman Dwight Worden.

KAABOO has a five-year-contract with the Fairgrounds.

If safety or other issues aren’t addressed accordingly, that contract could be revoked.

But officials say KAABOO has been diligent about being a good neighbor and has actively tried to remedy noise concerns.

Festival organizers are now working with Fairgrounds officials to fix any safety issues.

A 102-year old hotel in the East Village opened its doors to dozens of homeless veterans and at-risk youth in San Diego on Monday.

Hotel Churchill was renovated into a housing building with affordable rental studios that include a kitchen and a bathroom. There will be 72 units inside the hotel that will house 56 homeless veterans and at-risk youth.

The project is part of San Diego Mayor Kevin Faulconer’s Housing Our Heroes Campaign, which began in March.

"We've restored this historic building, breathing new life into it so it can provide quality affordable housing for men and women who served our country. Now they have housing and the support to turn their lives around," said Mayor Faulconer in a statement.

On Monday, he joined other local leaders and community members at the reopening ceremony. He said this is a very important step for San Diego in helping get homeless veterans off the streets.

“The good news is that we are a third of our way to our goal. We've already secured housing for more than 320 veterans and the list is growing every week,” he said.

Hotel Churchill also includes on-site social services and case management for qualifying residents who meet the Housing First model implemented by the City of San Diego and the San Diego Housing Commission (SDHC).

Luis Milan, a Navy veteran and new resident of Hotel Churchill, says he found himself on the streets one day and after his unemployment ran out, things just went downhill for him. He spent most of his time in La Mesa or Lemon Grove, carrying all of his things with him.

But he says now he feels safe.

“I don’t have to worry about being chased off by police or being attacked by anybody so I really feel safe there,” Milan said. “I have my privacy that I need. I can cook my own food, which makes me happy.”

The Navy veteran also thanked everyone involved in the program on behalf of all of the 56 veterans.

Interest never sleeps. That's good if you're an investor but bad if you're in debt.

"People struggle with debt at all income levels," said UBS Wealth Management Adviser Andy Galewski.

He says today it is easier than ever to get into debt. Credit cards and online shopping means you can rack up your credit cards in no time.  

"I think what happens a lot of times is that people just don't pay attention to the debt that they accumulate," said Galewski.  

But that changes when those payments become more than they can pay off. Falling behind in your payments and piling up consumer debt can impact your credit score and credit worthiness. That can mean higher interest rates on everything from credit cards to home loans.

"All to often they don't understand the consequences of building that debt and how quickly it can accumulate," said Galewski, and how hard it is to pay that down once you've built that up to a big number."

The key is to make paying off higher interest loans a priority.  It means cutting back on expenses, making a payment plan and avoiding further debt.

Some experts say you need to start paying high interest loans before making other financial commitments.  At the same time, you need to start putting away money for the future, an emergency or reserve fund to soften unexpected expenses.

Galewski admits there is good and bad debt. Bad debt are things like credit cards, electronics and appliances. Good debt is more like a house payment where interest rates are lower and you often have tax benefits.
