Two suspects are on the run after what police are calling a targeted attack in Emerald Hills. 

According to investigators, two gunmen walked up to a man working on his older model car in Emerald Hills Park and opened fire around 5 p.m. Sunday.

Witnesses described hearing four to eight shots.

One woman who didn’t want to be identified said she was walking to the park to meet some friends when the gunshots erupted.

"I was trying to figure out if they were those little fire crackers you throw on the ground and they pop. That’s what it sounded like at first," she told NBC 7. 

San Diego Police said the suspects ran southbound on Kelton Road and may have escaped in a gray colored car, possibly a Nissan.

According to investigators the two gunmen were described as 15 to 17 years old.

Friends drove the 46-year-old victim, who is not yet being identified, to the hospital where he later died.

"They seemed to just strike the victim, so we do believe he was the target of this attack and the motivation isn’t known at this time," said Lt. Manuel Del Toro.

Investigators said the suspects were wearing dark pants and hoodies.

The location of the park is on Bethune Court near Kelton Road, south of State Route 94.

Anyone with information related to this incident can call the San Diego Police Department’s Homicide Unit at 619-531-2293 or Crime Stoppers at 888-580-8477.

Friends and family of a former Encinitas resident are planning to install memorial benches in his honor after the news that he was killed on Maui over the weekend.

Michael Colby, 39, was found dead March 18 near Ka‘a Point, just west of Kanaha Beach.

On Friday, a 16-year-old boy was arrested in the case. The following day, Maui police arrested Healohaomakanaamekai Akahi Pua, 24. Pua faces charges of second-degree murder and is being held on $1 million bail.

Colby’s friends raised money to hold memorial tributes to Colby in Maui and Encinitas, where he lived five years ago before moving to Hawaii.

The artist had an Etsy profile that described his artwork as plain air, water color landscapes and life drawing.

So his friends and family are working to install benches in his name in Maui and at Orpheus Park in Encinitas.

The Maui bench dedication event will be on August 17. A date for an Encinitas ceremony was still to be determined.

National retail chain Sports Authority's future looks pretty bleak. 

The company announced in early March that it planned to close 140 of its 463 stores and filed for Chapter 11 bankruptcy protection in Delaware, using the store closings to attempt to save its finances.

But just last week, Sports Authority indicated that it's giving up on that plan and is choosing to auction itself off instead, according to Fortune. Despite media reports over the weekend, the company has not said whether it will shutter its entire fleet of stores, Fortune reported. 

There are a total of nine Sports Authority locations in San Diego County, and in March, the chain said it planned to shutter seven of them.

The full list of stores set to closed has not yet been announced.

The closures leave the sporting goods selection bleak for San Diego shoppers. Last month, the Sports Chalet, a longtime staple, announced plans to close three local locations.

Company lawyer Robert Klyman spoke on Sports Authority's future at a U.S. Bankruptcy Court hearing in Delaware last week.

"It has become apparent that the debtors will not reorganize under a plan but instead will pursue a sale," he said, according to The Wall Street Journal. 

A court supervised auction for the company's assets will be held on May 16, Fortune reported. The retail chain holds more than $1.1 billion in debt, and may be using the sale to help save its remaining stores.

NBC has reached out to Sports Authority for comment.

More than a dozen people had to leave their homes in the middle of the night after fire damaged an apartment complex in Ocean Beach.

San Diego Fire-Rescue crews were called to Del Monte Avenue at 12:30 a.m. for smoke pouring out of a wall.

Firefighters put out the small fire, but the structure was the main concern.

Officials say it appeared the garage was sagging.

Firefighters told 20 people to leave their homes while an engineer was called to make sure the building was OK.

After a couple hours, people were allowed back in.

Who knew that a dull grey concrete barrier along U.S. 101 in Burlingame, California near the San Francisco International Airport would become a tourist attraction?

But it has.

After Republican presidential candidate Donald Trump was forced to negotiate an unorthodox entrance – hopping a fence off the highway, essentially - into the California GOP Convention on Friday, looky-loos have started to visit there to snap selfies.

The political Calbuzz blog on Saturday captured one such family – a man and three children – taking pictures by the so-called “Trump Fence” to document the historical concrete barrier, where Caltrans has been working to widen the highway.

“They’re kind of liberal,” the unnamed father told Calbuzz of the kids. “It’s important for them to see this.”

For his part, Trump has capitalized on entering the Hyatt Regency via highway entrance because he was blocked by protesters who were carrying signs that read “Stop Hate,” and “Suck it, Trump.”

He got a lot of laughs when he kicked off his speech by joking: "I felt like I was crossing the border."

Protesters who surrounded San Diego State University's president as he left his office last week met Monday with administrators.

Students from SDSU’s Justice in Palestine and Muslim Student Association met with university leaders, including President Elliot Hirshman, to discuss signs that were posted throughout campus.

Last week, students swarmed President Hirshman after administrators did not openly condemn the posters, which identified specific individuals as terrorists or terrorist enthusiasts.

After Monday's meeting, a joint statement was released concluding the conference allowed both sides to express concerns as well as agree that protecting members of SDSU is a priority.

“We concluded by agreeing that in cases where racism, islamophobia, misogyny, homophobia and all forms of bigotry result, we abhor the content of such expressions, even as we recognize the protected status of these expressions,” read the university’s statement.

The signs were originally created by the David Horowitz Freedom Center, which describes themselves on their website as an organization that "combats the efforts of the radical left and its Islamist allies to destroy American values and disarm this country as it attempts to defend itself in a time of terror."

Moving forward, student organizations such as the Muslim Student Association, Associated Students and the University Senate will work together to review the school’s guidelines to allow freedom of expression while also protecting members of the community from harassment.

Your body doesn't want you to lose all that weight. 

A study that followed 14 of the 16 contestants from Season 8 of "The Biggest Loser" six years after the season ended has detailed just how the body fights against efforts to keep off the pounds. 

"The key point is that you can be on TV, you can lose enormous amounts of weight, you can go on for six years, but you can't get away from a basic biological reality," Michael Schwartz, an obesity and diabetes researcher, explained to The New York Times. "As long as you are below your initial weight, your body is going to try and get you back."

The study, published by the medical research journal "Obesity," focused on resting metabolic rate (RMR), which slows with weight loss, and whether or not slowing of RMR persisted over long periods of time.

The study hypothesized that the degree of that metabolic adaptation would be correlated with weight gain. Virtually all of the contestants put significant weight back on in the last six years, but the troubling part for the researchers was that their RMR remained quite low, not returning to their pre-"Biggest Loser" levels.

Danny Cahill, who won Season 8, dropped from 430 pounds down to 191 pounds during the show. He is now back up to 295. But his metabolism now burns 800 fewer calories per day than would be typical for a man of his size, making it more difficult to maintain or reduce weight.

Dina Mercado had a similar experience. She was 248 pounds before "The Biggest Loser" and 173.5 pounds at the finale. She is now back up to 205, but is, like Cahill, burning calories at a reduced rate relative to her size. She should be able to metabolize an additional 437.9 per day.

The study concluded that "long term weight loss requires vigilant combat against persistent metabolic adaptation that acts to proportionally counter ongoing efforts to reduce body weight."

Officials are still trying to identify the person connected with a leg bone found inside a boot that washed ashore in Carlsbad.

A black rubber boot with a leg and foot bones were found approximately 70 yards south of the beach access stairs off Carlsbad Village Drive and Ocean Street in March.

In a report released Monday by the San Diego County Medical Examiner’s Office, investigator say the bone comes from a mature man based on its size.

They are unable to identify the ethnicity of the deceased but say a feature often found in skeletons of Asian or Native American ancestry is not present in the tibia.

The leg bone was covered by a basic tube sock. The boot was not deteriorated but officials estimate the bones were dry so the person may have been dead for many months.

Using the measurement of the bone, the medical examiner estimated the deceased to be an estimated 6-foot, 1-inch tall give or take 2.5 inches.

The medical examiner believes the cause of death is likely drowning but the investigation is ongoing.

The victim's family has not yet been notified.

It was just two years ago that 20-year-old Morgan Hill learned she had been the subject of major news headlines across Chicago as an infant.

In October 1995, Hill, who was a newborn, was left for dead by her mother in a dumpster in suburban Hoffman Estates. She was rescued by a construction worker who was dropping off garbage. 

“He was dropping off the last load of trash from the construction area he was working on,” Hill said. “Before he dropped it in, he heard a whimper. He found a white kitchen bag that was double knotted.” 

Hill was taken to a nearby hospital, where nurses named her Mary Grace. She was later adopted and became Morgan Hill.

After learning the story of how she was saved, Hill set out to find the construction worker who saved her. 

“I have known I was adopted my entire life,” she said. “But two years ago I found the full story, and I have been trying to find that construction worker ever since.” 

NBC affiliate KHSB tracked down the construction worker, Gerald Rocky Hyatt, and on April 20 Hill was reunited with the man she now calls her “guardian angel.”

“I broke into tears and the first thing I said was, ‘Thank you,’” Hill said. “He said to me, ‘Baby girl, you are so loved.’" 

Then he gave Hill an angel pin he has had for more than 20 years.

"I've worn it every day since," Hill said. 

Hill’s adoptive mother, Sandi Hill, has kept many of the clippings about baby Mary Grace in a binder. This month, she added a picture given to her by the construction worker, whom she credits with giving her the daughter she always wanted.

“Rocky said God brought us together and he was so right,” she said. 

Morgan Hill said she’s not only grateful to Hyatt for saving her life, but she hopes her story will help save others. 

“I could not thank him enough,” Hill said. “He gave me a chance to live a second life. Because if he didn't find me, I would not be here to help others and show soon-to-be mothers that there are so many options out there and you don't have to throw your baby away.”

A worker suffered burns Monday after a fire sparked in a shop's paint booth and he attempted to put it out, officials said. 

The fire broke out around 4:27 p.m. Monday on the 100 block of N Glover Avenue at the site of a cabinet shop, fire officials said. It was put out shortly after. 

Chula Vista Fire Department (CVFD), San Diego Fire-Rescue (SDFD) and National City Fire Department (NCFD) officials responded to the fire, arriving to find the paint booth inside the shop engulfed in fire. 

As the man tried to put out the fire, he got burned. 

Smoke and fire could be seen from an attached shed.

The man was taken to the UC San Diego Burn Center, authorities said. It is unclear how severe the burn injuries are. 

No other information was immediately available.

Some residents in Del Mar say they are tired of hearing loud motorcycles in their community and want to find a solution to decrease the noise.

The issue goes up before the Del Mar City Council during Monday night’s meeting.

It was first brought up during a city council meeting on April 22nd. Members of the community say the noise has been getting worse over the years and it’s especially bad on the weekends.

Council members asked the Sheriff's Department to help enforce noise ordinances while they try to work out a solution to the issue.

Kris Nelson, owner of La Boutique on Camino del Mar says motorcyclists ride through by the dozens at times, setting off car alarms as they ride by.

Nelson says the glass display cases in her store rattle and if a large group rides by, she has to stop speaking with customers until it quiets down.

"The reason they have those engines is because they like the noise,” she said.

She says she doesn’t want to stop anyone from having fun but the noise does impact everyone. And she is glad to hear council has some solutions.

"It would be great if they would try something but I'm not sure necessarily what that solution is." 

Another man tells NBC 7 the loud noise is disturbing especially late at night and early in the morning.

Potential solutions would be to make certain north and southbound road quiet zones and add roundabouts to slow traffic.

But Nelson says speed isn’t necessarily what causes the loudness. It’s the riders revving their engines.

“When they come in groups, there is easily 25 plus at a time that will go through here,” she said.

Another woman who frequents Del Mar says she understands motorcyclists like be out enjoying the scenic drive through Del Mar and hopes a solution that makes everyone happy can be found.

One person was injured when a vehicle collided with a San Diego Police patrol car in Paradise Hills early Monday.

Two cars were involved in the crash near Potomac Street and Paradise Valley Road at 6:11 a.m.

SDPD and San Diego Fire-Rescue crews responded.

The driver of the civilian car was taken to a nearby hospital with what officials described as minor injuries.

The officer was not injured.

San Diego Police traffic officers are investigating the cause of the crash.

Consumer advocates are accusing San Diego public utility officials of tacking unnecessary fees and penalties onto late bills and shutting off customers' water with no warning.

The San Diego Union-Tribune reports that the Utility Consumers' Action Network says the city has been piling on fees and penalties, including years-old parking tickets and library fines, before agreeing to restore water service.

City officials say they try to accommodate customers who experience short-term financial problems, but that water service can't continue indefinitely without bills getting paid.

City spokeswoman Katie Keach says the City Council has recently approved a new program to help provide support to people who cannot keep up with utility costs.

Utility Consumers' Action Network officials say that isn't enough and that the city should stop shutting off water without notice.

Riders were stuck on the California Screamin' ride Monday at California Adventure, the sister park to Disneyland, after someone took out a selfie stick and the ride was halted, officials said.

The riders were escorted off the ride by 6 p.m. after waiting for 20 minutes, a Disneyland spokesperson said.

Disneyland officials said someone whipped out a selfie stick, which is banned from the park and rides. 

Disneyland officials said the ride is stopped any time a selfie stick is taken out as it poses a safety risk.

The ride was to resume shortly after evacuating riders. 

Selfie sticks were banned from Disneyland and California Adventure in 2015.

In a similar incident in June, California Screamin' was stopped because a rider pulled out a selfie stick.

Four 69-foot tall beer tanks arrived at the Port of San Diego Thursday for Ballast Point Brewing & Spirits.

The 24-ton fermentation and storage tanks will be used to brew all of the main production beers at its Miramar brewery, including Sculpin IPA and its flagship beer.

All four tanks were manufactured in Ludwigsburg, Germany.

The company had previously shipped most of its equipment through Long Beach before having it driven to San Diego, according to a Port of San Diego press release.

“We are fortunate to have experienced rapid growth recently, and with that we must keep up with increased distribution. We are constantly adding new tanks and equipment to expand production at our main Miramar brewery,” said Hilary Cocalis, Vice President of Marketing for Ballast Point.

Miramar is the company’s main production facility.

Ballast Point Brewing & Spirits also has locations in Little Italy, Scripps Ranch and Home Brew Mart and a tasting room in Temecula.

California is five weeks away from the state's presidential primary, but with the focus on the presidential race, it's easy to forget there are some often overlooked and interesting small contests among those jockeying to be delegates at the Democratic convention in Philadelphia.

On Sunday, dozens won places on the Clinton and Sanders tickets for the state’s June 7th balloting.

The Republican White House candidates file their own slates of proposed delegates in each congressional district, and 10 proposed statewide delegates.

The Democrats held caucuses that turned the wannabe delegates into candidates themselves, doing retail politicking.

One of the top vote-getters on the Clinton side was Poway resident Judy Ki, looking to go to the convention as a Clinton delegate from the 52nd Congressional District.

She sold herself, big-time, to about 300 voters in a Miramar District union hall.

"My margin of victory were my personal friends,” Ki said in an interview Monday. “My hairdresser came out. Some of my neighbors came out."

A long career as a middle school science teacher readied Ki for just the kind of research and presentations that serious politics demands.

“Doing any campaign is logical and sequential. It's like setting up a science experiment," she said. "You do step one, step two, step three, step four, right?"

Ki’s showing at the caucus would seem to make her a lock for Philadelphia in late July -- on her own dime, of course.

Or more accurately, somewhere in the neighborhood of $4,000 -- unless she can partner up for a hotel room.

"The (hotel) room is the most expensive. I don't eat a lot and the flights are fine -- I have lots of mileage,” Ki said with a hearty laugh. “But this is so exciting. This is on my bucket list, believe it or not.”

The second-place finisher at the 52nd District Clinton caucus was Jennifer Campbell, a retired physician who lives in Clairemont.

Her family is steeped in Democratic Party politics; her cousin is David Axelrod who served as President Obama’s campaign manager.

"My mother was a great politician in Colorado, and she was one of the first Democrats for (John F.) Kennedy,” Campbell told NBC 7. “And Kennedy used to call my house when I was a kid -- I talked to him on the phone. And it was just marvelous. And I got to go see his acceptance speech in 1960."

Campbell has met Hillary Clinton at Clinton's home in Washington when she was a senator.

She'd seem to be a no-brainer for delegate-picking by Clinton's team if the Democrats went by California GOP rules – but captured more than enough hearts and minds at Sunday’s Miramar District caucus.

“Well, I was thrilled and surprised, but we did work hard and campaigned,” she said. “There were four of us on the team -- two men, two women -- we worked together. And all of our friends and supporters, people who've known us for years in the Democratic Party came out to support us. And it was just wonderful, a wonderful day."

Campbell also appears to be likely to wind up in Philadelphia, and for the sake of her budget, she has relatives there who could spare her a hotel stay.

A motorcyclist was killed in a crash with a DUI suspect Friday in San Diego's North County.

The deadly collision happened on southbound Interstate 5, south of Poinsettia near Carlsbad, around 3:47 p.m., CHP confirmed.

A 27-year old woman believed to be driving under the influence was changing lanes when she and a motorcyclist collided.

The motorcyclist was thrown off his bike, officials said, landing in brush on the right shoulder of the freeway. The impact caused his helmet to fly off his head.

The motorcyclist was identified by the San Diego County Medical Examiner's office as Jaime Lopez-Martinez. 

CHP says a passerby stopped to help but the motocyclist did not have a pulse. He was pronounced dead at the scene a short time later.

The woman, a Los Angeles resident, was arrested for DUI and taken to Vista Detention Facility. She is scheduled to appear in court Tuesday.

The fatal crash is under investigation. CHP officials said the motorcyclist was splitting lanes at an unknown speed when the crash happened. It is unknown how fast he was traveling

An international team of astrophysicists have discovered three Earth-sized planets orbiting near the habitable zone of a dwarf star only 40 light years away from our Earth.

The nearby discovery, detailed in the latest edition of Nature, means astronomers will one day be able to study the composition of the planets and their atmospheres in search for chemical signs of life.

“The kind of planets we've found are very exciting from the perspective of searching for life in the universe beyond Earth,” said Adam Burgasser, a professor of physics at UC San Diego’s Center for Astrophysics and Space Sciences and a key participant of the international team, in a statement.

UC San Diego (UCSD) astrophysicists worked with team members from across the globe in Chile, tracking the star’s light moment-to-moment over the course of 62 nights last September to December. Scientists used a TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) at the La Silla Observatory is Chile.

When astrophysicists look another look using larger telescopes, they found the planets orbiting the ultracool dwarf star were similarly sized to Earth.

Two of the planets have orbital periods of approximately 1.5 days and 2.4 days respectively. The third planet has an orbital period between 4.5 and 73 days.

“With such short orbital periods, the planets are between 20 and 100 times closer to their star than the Earth to the Sun,” said Gillon in a statement. “The structure of this planetary system is much more similar in scale to the system of Jupiter’s moons than to that of the Solar System.”

The star in the system, TRAPPIST-1, is cool, red, dim and so small it is invisible to most telescopes. The star is a little larger than Jupiter in diameter and half the temperature of our sun.

"While such a ‘cold’ star might sound exotic, many, if not most, of the stars in our Milky Way Galaxy are of this cool, red, small and dim variety,” Burgasser said. “If Earth-like planets around these stars turn out to be common, there may be many more habitable planets out there than current estimates predict.”

The inner planets may have rocky surfaces and, because of their close orbit to their star, only receive four times and twice, respectively, the amount of radiation received by Earth. They lie just inside the habitable zone, an orbital distance where surface water and life is likely. The outer planet may still lie within the habitable zone, but scientists do not know enough about its orbit yet.

“Fortunately, we may be able to answer these questions in the near future, as the geometry of the system makes it likely that we will be able to detect the atmospheric gases of these planets in the next decade with the launch of the James Webb Space Telescope,” Burgasser said. “This facility will allow us to search for biogenic gases--oxygen or methane for example--that would firmly indicate the presence of life, or search for other gas species that would tell us about the planets' compositions, geothermal activity and evolutionary history.”

The team is led by Michael Gilleon of the University of Liege, Belgium. It involves researchers at UCSD, MIT, NASA’s Johnson Space Center in Houston, Cavendish Laboratory in Cambridge, England, and the Indian Institute of Astrophysics in Bangalore, India.

A Fantasy 5 ticket worth $543,579 has been sold at an Encinitas Vons store.

The ticket is the largest Fantasy 5 prize won so far this year in California, state lottery officials said.

The lucky ticket matched the winning numbers 19-23-32-35-36 and was sold at the Vons Grocery store at 453 Santa Fe Drive.

This is the largest Fantasy 5 prize won since the Oct. 2, 2015 prize worth $610,882 bestowed to a LA resident.

The winner has not yet come forward and has 180 days from the drawing, which was Feb. 2, to claim the money.

Lottery officials urge the winner to sign the back of their ticket in ink and contact the California Lottery or visit any of the nine Lottery district offices as soon as possible.

The military is launching tests on the world's largest unmanned surface vessel -- a self-driving, 132-foot ship designed to travel thousands of miles out at sea without a single crew member on board.

The so-called "Sea Hunter" has the potential to revolutionize not only the military's maritime service but commercial shipping -- marking the first step toward sending unmanned cargo vessels between countries, according to military officials, who showed off the ship in San Diego on Monday before it was put in the water.

The Pentagon's research arm, the Defense Advanced Research Projects Agency, or DARPA, developed the ship along with Virginia-based Leidos. DARPA will test it in conjunction with a team from the Space and Naval Warfare Systems Command (SPAWAR) over the next two years off California's coast. The tests will largely focus on its ability to react on its own to avoid collisions with seafaring traffic.

“I feel fantastic. I mean it’s really quite exciting to be able to be part of the showcasing event with the navy,” said Jerry Dejaco, a representative from SPAWAR.

During the testing phase, the ship will have human operators as a safety net, but once it proves to be reliable, the autonomous surface vessel will maneuver itself -- able to go out at sea for months at a time.

Program manager Scott Littlefield said there will be no "remote-controlled driving of the vessel," instead it will be given its mission-level commands telling it where to go and what to accomplish and then software will enable it to drive itself safely.

The military initially built the diesel-powered ship to detect stealthy electric submarines, but developers say they believe it has the capability to go beyond that, including doing mine sweeps. There are no plans at this point to arm it.

"There are a lot of advantages that we're still trying to learn about," Littlefield said.

Among them is the possibility that the full-size prototype could pave the way to developing crewless cargo vessels for the commercial shipping industry someday, he added.

The ship was built off the Oregon coast, and moved on a barge to San Diego's coastline to begin testing. The prototype can travel at a speed of up to 27 knots per hour, and is equipped with a variety of sensors and an advanced optical system to detect other ships, Littlefield said.

The program to develop the ship cost $120 million, though Littlefield said the vessels can now be produced for about $20 million.

During the collision tests, the ship will be programed to follow international traffic rules for boats of its size, Littlefield said. There are no standards for unmanned ships yet, but he believes that could change if vessels like this one make it out of the experimental stage.

“So we envision maybe several of these vessels going out with a carrier group and being able to run a perimeter and make sure that nothing dangerous gets through to our more valuable assets," said Jared Adams, Press Secretary of DARPA.

The Navy over the years has experimented with a number of unmanned systems -- from drone helicopters to small, remotely controlled boats launched from ships. The Pentagon's budget over the next five years calls for investing in more high-end Naval ships, including $600 million to be invested in unmanned undersea vehicles.
