Illegal border crossings along the southern border are dropping.

President Donald Trump says it's thanks to his administration but the numbers show otherwise.

The apprehensions of undocumented immigrants has been declining for over a decade.

On Sunday, the President tweeted: "General Kelly is doing a great job at the border. Numbers are way down. Many are not even trying to come in anymore."

Stopping illegal immigration may have been a signature promise of President Trump, but experts said the decline in numbers is part of an ongoing trend that began years before Trump took office.

“Most immigrants aren't trying to cross the land border anyways,” said Ev Meade, Director of the Trans-border Institute at the University of San Diego (USD). “Usually what they do is overstay their visas.”

Illegal immigration peaked in the mid 80's and then again in the year 2000.

That's when roughly 1.6 million undocumented immigrants were detained.

The number of apprehensions has been in decline every since, according to data provided by the U.S. Customs and Border Protection (CBP).

In 2016, about 415,0000 undocumented immigrants were apprehended.

“There's been a lot of talk about hiring new border patrol agents, but nothing new has happened there yet,” said Meade. “There are no new boots on the ground, so this administration can't really take credit for the drop.”

Currently the majority of undocumented immigrants are from El Salvador, Honduras and Guatemala. Immigration from Mexico, has been declining for years.

“Mexican migrants are not coming in large numbers to the U.S anymore,” said Meade. “In fact, net migration is negative, meaning more Mexicans are returning to Mexico than are coming to the United Sates.”

It may be too soon to tell if the "Trump Effect" is having a real impact along the border, but downtown resident, Peter Jones said he appreciates that President Trump is unapologetic discussing the topic.

“The question is, are we a nation of laws and do we want to enforce the law,” Jones told NBC 7. “We can't selectively enforce laws or not enforce laws, that doesn't work. It's something that needs to be talked about.

Matthew Mendenhall worked in federal court for 25 years. The Clairemont resident said Trump's approach doesn't make sense.

“There is no reason to build a wall, immigration has been declining,” said Mendenhall. “It's a shameful disgrace.”

As the debate over immigration continues across the country, companies hoping to design or build the border wall are getting ready for the bidding process. On Wednesday the federal government will study prototypes of the new border wall, before it selects its finalists.

The estimated cost for the border wall is $20 billion.

Some Santee residents say sinkholes have opened up dangerously close to their homes while the city argues over who is responsible.

The collapse of old city drainage pipes running under private property is the problem.

On Monday, city crews covered up one sinkhole, 6-feet wide and 6-feet deep. Workers also shored up a larger hole between two homes on West Hartland Circle.

It's the first effort made to contain this growing problem, but the solution still seems a long way off.

Since January, Sergio Guerre, a father of three children, said he has watched the sinkhole grow five times its original size.

"The one I worry about is the 3 year old," Guerre said. "You can only control him so much."

On the other side of the fence is neighbor Vernon Gilmore. He told NBC 7, he cares for an aging mother-in-law and a 3-year-old grandchild.

“I thought this is where I was going to stay forever but like I said, if it's not safe, it's not worth staying around,” Gilmore said.

A 24-inch drain pipe between the homes used to channel water away from West Hartland Circle collapsed some time ago. Heavy rains washed away the soil, causing two sizable sink holes to form.

“I am out here at all hours of the night constantly waking up in the middle of the night and coming down," Guerre said.

While it's a City of Santee drain pipe, homeowners received letters saying it was their responsibility to fix it.

"They say they have been working on this problem for months but they haven't talked to us," Gilmore said.

Attorney Patrick Catalano filed two complaints on the homeowner's behalf. Catalano said four more clients have similar issues with the city.

Repairing the aging infrastructure and shoring up homes could cost hundreds of thousands of dollars.

"I'm cautious because there are band aid fixes and there are real fixes,” Catalano said.

"Is it going to stop or is it going to continue? At what point is my house in danger," Guerre asked.

The City Manager declined to comment for our story.

According to a Development Services report presented to the Santee City Council last week, there are 12 such drain systems on private property.

It's estimated replacing or repairing them all would cost the city more than $1 million.

The House of Representatives approved a measure on Tuesday that would keep the Federal Communications Commission from enforcing rules passed last year that would ban internet, cable and mobile providers from selling your data without your consent.

With strong opposition from Democrats, the measure narrowly passed in the House by a 215-205 vote. No Democrats voted for the bill, and 15 Republicans opposed it. A similar version squeaked through the Senate last Thursday on a party-line vote of 50-48.

As NBC News reports, the White House said in a statement on Tuesday that Trump "strongly supports" the repeal, while internet privacy advocates frame this as a battle between privacy and profits.

Kate Tummarello, a policy analyst at the San Francisco based Electronic Frontier Foundation, said the "commonsense rules" Congress voted to repeal were designed "to protect your data" and keep internet service providers from doing a "host of creepy things" without your consent.

Rachel Dolezal, the former head of an NAACP chapter who for years passed herself off as black, is giving some context about how her upbringing shaped her search for identity in her new memoir.

Now identifying as trans-black, Dolezal sat down with NBCBLK to discuss how her identity challenges white supremacy and why she just couldn't be a white ally.

"I said I tried the 'ally path' in my earlier young adulthood," Dolezal said. "I did a lot of work but it wasn't as much in harmony with me being seen and understood for who I am, and that just kind of all synchronizing, in my life."

She also wishes she had introduced herself and her identity, rather than have it come out when a reporter asked her, "Are you African American," and she was unable to answer.

Ajinomoto Windsor, Inc. is recalling more than 35,000 pounds of frozen "José Olé" taquito products that may be contaminated with rubber and plastic, according to the United States Department of Agriculture. 

The Lampasas-based company recalled 60-ounce packages of the frozen beef taquitos produced on Dec. 30, 2016. The recalled items include the case codes 3366365A, 3366365B, 3366365C and 3366365D and a "best by" date of Dec. 30, 2017.

The company initiated the recall after receiving two complaints of foreign material in its ready-to-eat beef products earlier this month. The foreign materials were pieces of rubber with white plastic that originated from the establishments processing equipment.

According to the USDA, there have been no confirmed reports of adverse reactions due to consumption of these products.

The items were shipped to retail locations in California, Florida, Illinois, Missouri, New York, Ohio, Pennsylvania, Wyoming and Texas.

Consumers who have purchased this product are urged to throw it away or return it to the place of purchase.

A former FedEx driver and the founder and chief investment officer of a local management firm was sentenced to more than two years in prison for stealing more than half a million dollars from local investors.

Joshua Knaup, 41, opened up an investment management fund, EquityPro Capital, in Downtown San Diego after he lost his job at FedEx.

In 2013, he claimed to have started "The F2 Fund" and duped victims into investing hundreds of thousands of dollars in the non-existent hedge fund.

In one instance, he convicted Bankers Hill couple, Lois and Henry Mathews to invest $240,000 during a celebration for the couple's wedding anniversary. 

Another victim from Coronado lost more than $130,000. 

According to court documents, a Border Patrol agent also became a victim of Knaup's after investing $10,000. When the agent asked Knaup to return his money, Knaup wrote him a check that bounced.

“Mr. Knaup perpetrated a scheme weaved with facades and lies to prey on trusting, hard-working people intending to make legitimate investments,” said Special Agent in Charge Eric S. Birnbaum. 

Knaup used the money from investors on personal expenses, including his office space in downtown. 

When investors began to realize Knaup had never invested their money in a hedge fund, he ran away to Mexico.

Knaup was sentenced Monday to 33 months in prison and order to pay $556, 639 in restitution. 

The wife of Khalid Masood, the terrorist who attacked Britain's parliament, said she is "saddened and shocked by what Khalid has done," NBC News reported.

In a statement given to London's Metropolitan Police, Rohey Hydara condemned her husband's actions and expressed her "condolences to the victims that have died." She also wished a "speedy recovery to all the injured."

"I would like to request privacy for our family, especially the children, at this difficult time," the statement said.

Masood killed four people in his attack on Parliament and the Westminster Bridge, including a police officer and three civilians, before being shot dead. Though ISIS claimed responsibility for the rampage, there is no evidence Masood acted in the name of the terror group.

New recommendations from the American College of Physicians (ACP) on the treatment of addiction will help physicians shift perspectives on how they treat the disease, a San Diego addiction specialist said. 

On Monday, the ACP issued comprehensive recommendations for doctors prescribing and treating addiction disorders. 

Some of the guidelines included asking physicians to become more familiar with appropriate guidelines related to pain management and controlled substances like prescription opioids and non-opioid drugs, becoming familiar with Prescription Drug Monitoring programs, learning more about naloxone, a drug used to reverse overdoses and learning more about medication-assisted treatment of opioid use disorders. 

The recommendations speak to something addiction specialists have known for years, said Clark Smith, M.D., an addiction specialist and director of Recovery Works in San Diego, a clinic offering help to those addicted to alcohol and drugs. 

“The big thing today is, you know, they're saying what people in the addiction field have been saying for 20, 30 years: addiction should be considered an illness, just like any other illness," Smith said. "It’s treatable, it responds to treatment and may need lifelong treatment."

To effectively treat those addicted to alcohol and drugs, Smith said, doctors need to shift their perspectives on the disease. Oftentimes, he said, when addicts go through a hospital detox, they do not get any kind of treatment when they finish - and they end up relapsing. 

One way to help patients looking for long term success is through proper prescribed addiction medication, Smith said. The first six to 12 months after detox and making the change to get sober are crucial, he added. 

That's why the ACP's recommendation asking physicians to improve their training in the treatment of substance use disorders, including with buprenorphine-based treatment, is so important, Smith said. 

Buprenorphine is the first medication to treat opioid addiction that can be prescribed in physician offices. The medication reduces cravings and withdrawal symptoms. 

The move to ask physicians to consider medication to treat addiction is important, Smith said, because patients "really benefit from getting medication treatment, not just rehab or 12 steps - that actual medicational treatment makes a difference and gives them better success."

“With these medication treatments – and there are a couple others, Vivitrol is the most effective – the rate of relapse will go way down," Smith said.

Research from the San Diego and North County drug courts, Smith said, showed that patients who took all six doses of Vivitrol in their allotted times stayed drug free over the next two years. 

But the reason many doctors have not been prescribing medication to treat addiction lies in the past, Smith said. In the past, medications with methadone, and others, have not been effective, Smith said. 

“You know, a lot of addiction specialists don’t prescribe these medications either," Smith explained.

Some doctors still stick with old school treatments: 12 step programs, Alcoholics Anonymous, and power of will. While those can be effective for some, Smith said, using proper and effective medication can help longevity.

“Frankly they haven’t been very effective, especially for opiate addiction. So now we have new treatments and they’re much more effective and American College of Physicians is recognizing that and basically getting the word out that addiction should be treated like diabetes is treated," Smith said, referencing the fact that diabetes patients need constant treatment.

"They’re saying they’ll need lifelong treatment," Smith added. "Addiction is a chronic illness, although once people get clean and sober and are back to their own rehabilitation, they don’t necessarily need a lot of medical appointments."

Smith hopes that with these new guidelines comes a shift, and with that, more help for addiction patients. 

"Addiction specialists have been advocating for this for a while," Smith said.

A San Diego State University student, diagnosed with a rare form of cancer, is getting help from family and friends as she continues working toward her degree.

Joana Da Cass has many passions in life, including hiking with her dog. These days, the 25-year-old SDSU student is unable to enjoy some of her hobbies.

Family members said after months of feeling pain in an ovary, in early March of this year, Da Cass was diagnosed with undifferentiated carcinoma with rhabdoid features.

Pictures show Da Cass flashing her signature smile during her chemotherapy treatments.

“Seeing her smile and seeing the way she acts and facing this gives me strength to look at my life in a different perspective,” explained friend Jaqueline Rizzatti.

Despite the smiles, family does have concerns.

"To not have my cousin around, that’s the concern,“ explained cousin Renata Berto. “But we are keeping positive we believe in miracles.”

Family and friends have set up an online fundraiser to help offset the cost of treatment.

According to the GoFundMe page, Da Cass will graduate with a degree in International Business this spring. 

Local artist Ezekiel Morphis is also lending his voice for a fundraiser April 13 at Thorn Street Brewery.

“We’re just hoping to keep her stress free during this time,” Berto said. “So finances are a way of helping her not to have to focus on that and have the energy to fight this.”

Family members are hoping she will be able to stay on track to graduate this May from SDSU.

They say any additional money they raise will be donated to cancer research.

Cameras positioned on parking meters in Hillcrest were removed overnight. NBC 7 has been reporting on the new so-called vehicle detection sensors that were temporarily installed to gather data on spot occupancy.

As of this morning, the San Diego City Treasurer's office has not explained how much the cameras cost. NBC 7 has also asked the city treasurer if the cameras could be a precursor to new Smart Meters.

We were told the cameras are gathering data on occupancy rates, which provide information on the how the meters are being used.

However, it was not clear on why the city has decided to gather that data.

In Coronado, they're still working through technical issues, but Smart Meters have been installed with the sole purpose of "Clearing" any unused time once a vehicle leaves.

The small cameras were attached to parking meter poles in Hillcrest on Fourth Avenue between University Avenue and Robinson Avenue.

In Coronado, the city hopes sensors will detect when a vehicle left a spot and recalibrate so that incoming cars won't be able to take advantage of any time left on the meter from a previously parked vehicle.

They would also discourage drivers from coming back and re-feeding the meter when the two-hour time allotment was up.

In a previous interview San Diego City Communications Department Director Katie Keach said the sensors had been in place in Hillcrest for a couple of months.

Keach said the sensors were designed to be installed on a temporary basis in one section of Fourth Avenue.

Ford on Tuesday outlined new details for a planned $9-billion investment in the United States.

The automaker's investment push was first announced in 2015, but President Donald Trump suggested on Twitter that the "big announcement" was related to his effort to grow jobs in the U.S., CNBC reported.

Ford said Tuesday it would invest $1.2 billion into three Michigan plants. General Motors and Fiat-Chrysler have also made U.S. jobs announcements since Trump won the presidential election, though many projects had already been in the works.

Britain's King Arthur is a 62-year-old former soldier and biker gang member who leads a religious order of warrior-druids, NBC News reported.

Thirty years ago, John Timothy Rothwell became convinced he was the king from the myth and changed his name to King Arthur Uther Pendragon. Now he wears a sword and preaches to fellow pagans.

"Every day, I wake up Arthur, I go to sleep Arthur. I wake up a druid, I go to sleep a druid," he said.

About 4,000 Britons identify as druids. NBC News visited Arthur at Stonehenge for a gathering marking the spring equinox last week, where he was declaring war — over parking.

Parents addressed concerns regarding school safety during the School Board meeting Monday evening at Fallbrook High School.

Many parents told NBC 7, two lockdowns in just the past few months is not acceptable and something needs to change.

The first lockdown was almost two months ago. During that incident, a loaded gun was found on campus.

Then, the high school was put on lockdown last Wednesday, after a report of a gun on campus. Authorities did not find a gun and the lockdown was lifted after a couple of hours.

NBC 7 spoke with a teacher at Fallbrook High School who explained the first lockdown prompted more training for teachers on what to do in emergency situations.

Those training sessions were originally supposed to happen in the middle of April, but were moved up to this week since the there have now been two such incidents in less than two months.

Teachers will be trained on Thursday and Friday.

The training is called Options Based Response Training, focusing on different scenarios; like when to run, hide or fight. They will then teach their students. 

Many parents said they want a Sheriff's deputy assigned to the school. The School Board instead decided to hire nine unarmed security guards.  Monday night members of the Board said they're looking into ways of possibly bringing an armed guard on campus during school hours.  One parent, Nora Maier applauded the District's efforts.  

"I wanted as a parent to thank you all for your diligence at putting our student's safety in an abundance of caution," she said.

Enrique Acosta, father of two students at the high school is still concerned.

"You're out there and the kids are here and when you're outside you don't know what's going on inside, right? You don't know if there's somebody with a gun trying to harm somebody," he said.

The school held an emergency meeting with parents last Wednesday to go over student safety.

Monday night Board President Sharon Koehler spoke regarding the new safety training and precautions.  "his is a step beyond anything most schools would ever have to know, but better to know it and not need it than to need it and not know it," she said.

Several people were detained Tuesday in connection to an "ambush-style attack" on two undercover police officers conducting surveillance outside an apartment complex in northwest Miami-Dade, officials said.

The shooting happened just before 10 p.m. near Northwest 62nd Street and 20th Avenue. 

Miami-Dade police said the two officers were investigating gang activity in the area as part of a multi-agency task force. The detectives were in an unmarked police vehicle when, according to officials, several suspects "ambushed" the car and opened fire.  The officers returned fire, Miami-Dade Police Maj. Hector Llevat said.

"They were ambushed in their vehicle, unprovoked," Llevat said.

The wounded officers were rushed to Jackson Memorial Hospital in the bed of a pickup truck and were being helped inside by their colleagues, NBC 6 video shows. 

The officers, Charles Woods, 37, and Terence White, 47, were reported in stable condition and in good spirits, police said. Woods was treated for his injury and released, police said.

Hialeah Police said a suspect in the shooting later showed up at Hialeah Hospital with a gunshot wound. It was not immediately clear if the suspect was in police custody.

Officials on Tuesday said they had detained several individuals and were interviewing them to determine their possible involvement in the shooting. One suspect was detained at the Hyatt Place on Northwest 35th Street across from Miami International Airport.

No arrests have been made, police said. An investigation in underway.

Miami-Dade Mayor Carlos Gimenez and Miami-Dade Police Director Juan Perez arrived at the hospital where the officers were being treated. They asked the public's help in finding the shooters.

Woods is an 11-year veteran of the department and White has been on the force for 26 years.

"Our prayers go out to the speedy recovery of our officers and their families that really had the scare of their life tonight," Perez said. 

Miami Beach Police Chief Daniel Oates offered support to the injured officers on social media, tweeting: "@MiamiDadePD prayers for our partners and ready to offer any needed support from @MiamiBeachPD."

"We need you to step up to the plate. If you know something, if you saw something then say something. Today is the day to step up," Perez told reporters in pleading for help finding whoever is involved.

Police asked that anyone with information is urged to call Miami-Dade Crime Stoppers at 305-471-TIPS.

Pre-trial motions began in Superior Court Monday for a case involving a boy who died after playing with a rat bought from a San Diego Petco store.

The case stems from the 2013 death of 10-year-old Aiden Pankey.

One day, Pankey was rushed to the hospital with severe stomach pains. He died hours later. The San Diego County Medical Examiner's office ruled the boy's cause of death was streptobacillus moniliformis, better known as rat bite fever.

His family had just bought the boy a pet rat from Petco, a San Diego-based company. The CDC later confirmed the rat was infected. 

“The boy's grandmother purchased the male rat because her only grandson wanted a mate for his female pet rat,” the family’s attorney, John Gomez, said to NBC 7 back in 2014.

In a statement, the retailer expressed their condolences about the death. 

"We are deeply saddened by the Pankey family's tragic loss," Petco said in a statement. "The health and safety of people and pets is always a top priority, and we take the family's concerns very seriously."

Ahead of opening statements, San Diego attorney Gene Iredale talked with NBC 7 about the case and what may happen going forward. Iredale is not involved with the case. 

He says Pankey's attorneys will try to drive home a particular narrative. 

“This is a rat that Petco sold. They sold it without apparently testing it to see if it suffered from rat bite fever," Iredale said. "And they sold it without giving a warning that rats sometimes develop rat bite fever."

Based off the facts of the case, Iredale said, he believes the attorneys can prove the pet company is guilty of strict liability and tort, as well as negligence. 

Petco's attorneys, he said, will likely dive into the window of time between the rat's purchase and Aiden becoming ill to see if it is at all possible the rat contracted this infection after being bought.

Either way, Iredale said, the case has potentially huge implications for the business and families with these pets.

“Almost 1.2 million households in the US have rats that they keep as pets,” he said.

Opening statements in this case are set to begin on Tuesday in Superior Court Judge Eddie Sturgeon's courtroom. 

The City of San Diego has paid a cyclist $4.85 million after he suffered serious injuries while riding his bike on a sidewalk with uneven pavement, the largest settlement ever paid by the City of San Diego for such a case. 

In an accident in 2014, Clifford Brown was riding his bike on College Avenue in Del Cerro when he hit a portion of uneven pavement raised seven inches high.

He was launched more than 20 feet in the air, crashed into a sidewalk, was thrown off his bike and skidded another 10 feet further.

Brown suffered spinal injuries and head injuries. A neurologist determined that Brown had also suffered a stroke in a deep part of his brain from the impact. Days after the crash, he went into respiratory decompensation and cardiac arrest. Several teeth were also knocked out.

Through an attorney, he filed a lawsuit against the City of San Diego.

The lawsuit claimed the City was responsible for the poorly maintained sidewalk in Del Cerro. The City has been made aware of the sidewalk prior to the crash and even sent a crew to inspect it, according to Brown's defense attorneys. 

Tuesday, the City of San Diego will ratify the settlement. 

In a statement through a spokesperson, the City of San Diego said: “the settlement isn’t about making someone rich, but about making sure Brown is able to pay for his medical expenses for the rest of his life."

Local cyclists say they still see dangerous cracks and uneven pavement on City streets. 

“Via Capari, the descent off of Mount Soledad has a lot of very unsafe rises in pavement, cracks,and potholes. You know there are a lot of areas like that around the city," said bicyclist Stephen Roehrs.

Roehrs, the owner of Adams Avenue Bicycles, said he has also seen more and more bicyclists riding dangerously. 

"People driving and using cell phones is a huge risk for bicyclists," he added.

A personal injury attorney not associated with this case said city officials' efforts to save money during the Great Recession are likely coming back to bite them in the wallet.

“When you slash the funding and you have more areas that are in disrepair, you're going to have more injuries," said Nathan Cowan.

The female high school student who was planning to bomb her school and shoot students and teachers referenced the Columbine and Newtown attacks in her diary and believed she would be the first female mass shooter, police say.

Frederick County Sheriff Charles A. Jenkins revealed new details on Tuesday about what investigators found in Nichole Cevario's diary. The 18-year-old was pulled out a classroom at Catoctin High School after her father read threats in the diary and contacted the school.

Cevario referenced the horrific school shootings in Columbine, Colorado, and Newtown, Connecticut, Jenkins said. She focused on mistakes those shooters made, the sheriff said.

Also, she said she believed she would be the first female mass shooter. 

A 16-year-old girl opened fire at an elementary school in San Diego in 1979, and a woman was one of the shooters in the San Bernardino attack in 2015, among other examples. 

Cevario stockpiled bomb-making materials and had a shotgun to attack Catoctin High on April 5, the Frederick County Sheriff's Office said Monday. 

Police believe her diary entries were not empty threats, Sheriff Charles A. Jenkins said at a news conference Monday. 

"We felt this was going to be carried out. There is no doubt in our minds that we diverted a disaster up there," he said. 

Cevario "had the means and equipment to have caused a significant life safety event” at the school, police said in a statement. 

How the Investigation Unfolded

Police learned of Cevario's plot after her father read her diary and called the school on Thursday. Earlier, he found shotgun shells in her backpack, Jenkins said. He had noticed a change in her behavior. She already was seeing a counselor outside school.

Within hours of the father's phone call, the honor student was pulled out of a classroom and involuntarily taken to a hospital for a psychological evaluation. 

Police searched Cevario's home in Thurmont, Maryland, and found weapons and the diary. In the home, police say they found a 12-gauge shotgun with ammunition and bomb-making materials including pipes with end caps, shrapnel, fireworks, magnesium tape and fuse material.

The gun and other items were purchased legally, police said. Cevario reportedly planned to saw off the shotgun.

What Cevario's Diary Said 

Cevario's diary "spelled out a detailed shooting event that she planned to execute on a specific date in April," police said. 

Officials later said that date was April 5. It was not immediately clear whether that date had any significance. 

The diary showed the high schooler, who had been taking college classes in criminal justice and working at a carryout restaurant, had been planning the attack for some time, police said. She expressed frustrations about her personal life and compiled information on the school's emergency procedures and the school resource deputy on duty. 

"The journal was very detailed, including a time line that revealed how she was going to execute the plot, and her expectations at each stage of the event," police said. 

The sheriff said in an update Tuesday that Cevario named one male classmate and two female classmates in the diary. All three people were friends. Police believe they were neither targets nor accomplices, but did not release additional information. 

Investigators believe she had a second diary they cannot find.

What's Next

Officials say Cevario acted alone and never took a weapon or explosive device to the school. It was clear she had mental health issues, the sheriff's office said. 

"Obviously, this was a student who needed some intervention and some help, and I think the silver lining is she's going to get the help she needs now," Frederick County Public Schools spokesman Michael Doerrer said.  

Once Cevario is released from the hospital, she will be charged with possession of explosive and incendiary material with intent to create a destructive device. 

Law enforcement and school officials said they had no sign Cevario had any problem.

Life at Catoctin High was returning to normal Tuesday.

"It's crazy to think that this could be happening in such a small community," one student said. "I feel like you know the people at your high school, but really you might not."

Anyone with information for police is asked to call 301-600-2583. 

How to Tell If Your Child Needs Help 

Dr. Mary Alvord, a psychologist, said parents should watch for dramatic changes in their children's behavior. Note if children or teens suddenly withdraw from friends, hole up in their rooms for hours or fail to come home, she said. Changes in sleep patterns and eating habits, or increased irritability also can be signs something is wrong. 

"We're really looking for patterns of change," Alvord said.

San Diego County officials are renewing their warnings for pregnant women, women who could be pregnant and those considering pregnancy to avoid traveling to known Zika transmission areas after a baby with severe birth defects connected to the virus was born in San Diego County. 

The infant marks the first born in San Diego County with microcephaly associated with the Zika virus. The mother contracted the Zika virus while traveling in a foreign country where the virus is common. 

Microcephaly stunts brain development in fetuses, causing babies to be born with abnormally small heads and brains. The children typically have other developmental and neurological health problems as well. Microcephaly has multiple causes. 

“Pregnant women who must travel to one of these areas should strictly follow steps to prevent mosquito bites and speak with a health care provider upon return,” said Wilma Wooten, M.D., M.P.H., County public health officer, in a statement.

Authorities are not releasing details on the case due to privacy concerns. 

The Zika virus can be transmitted through mosquito bites from an infected mosquito or through sexual activity. 

Eighty-seven travel-associated cases of Zika have been reported as of March 24, according to the HHSA. 

Four of five who contract Zika do not show symptoms. Those who do show symptoms report having a fever, rash, joint pain and conjunctivitis. In most cases, the illness is mild and symptoms last for several days to a week after being bitten by an infected mosquito. 

To avoid mosquito bites, the HHSA recommends doing the following:

• Use insect repellents that contain DEET, picaridin, IR3535, oil of lemon eucalyptus or para-menthane-diol for long last protection when traveled. Pregnant women and women who are breastfeeding should use an EPA-registered insect repellent. 
• Wear long-sleeved shirts and pants
• Use air conditioning and keep windows closed, if possible. 
• Reduce the number of mosquitoes outside by emptying standing water from containers like flowerpots.
