Barona Resort and Casino security guards alerted San Diego County Sheriff's Department (SDSO) deputies to an international counterfeiting operation.

Deputies arrested Lien Do, Hao Nguyen, and Ben Ven Pham on Christmas Day last year.

They found $300,000 worth of counterfeit chips in the suspects' car.

"It appears that what they were seeking to do was convert those chips into cash and to walk out the casino with the cash," said Prosecutor Daniel Shim.

The defendants were charged with multiple felonies, including grand theft, burglary, forgery and possession of counterfeit marks.

"When the sheriff's department searched their home in Garden Grove, they found about $2 million in casino labels," Shim said. "During Mr. Pham's interview, he indicated he received those chips from Vietnam."

Two of the defendants plead guilty to lesser charges and are serving one-year jail terms. Charges against a third defendant were dropped and he returned to Vietnam.

"The Sheriff's department did a great job in investigating this case. They did a very thorough investigation," Shim said.

The criminal investigation expanded to at least six other casinos in Southern California, several of which are located in San Diego.

It remains unclear if any of the fake chips were actually used in any of those casinos.

"It is still unknown if the operation had any ties to organized crimes," Shim said.

More San Diegans with chronic pain are managing that pain, without powerful and addictive prescription drugs, according to a data analysis completed by NBC 7 Investigates.

Orville Dalager of Carlsbad is one of them.

He experienced chronic -- and at times -- excruciating pain in his fingers, hands, and wrists, caused by chemotherapy treatment for prostate cancer. Dalager said he couldn’t even open a car door without pain, so he turned to the prescription opioids tramadol, hydrocodone, and oxycodone for help; the tramadol gave him quick and significant pain relief.

“It’s like they went in with WD 40, and lubed the joints,” Dalager told NBC 7 Investigates. "Made it so I could do what I usually do, which is work with my hands."

But that pain relief came with some serious side effects.

“I felt groggier, a lot more forgetful,” Dalager explained. “Just no energy. And I got constipated. Yeah, that was no fun.”

Those side effects and concerns about addiction led Dalager to work with his doctor to find alternative solutions for his constant pain.

He began walking several miles a day, two or three times a week, on the beach in Carlsbad. On days when the tide is high, Dalager said he walks on the rocks at the top of the beach, which he said helps with his balance. He’s also doing yoga, a practice he said he once dismissed as “a bunch of creepy crap”, but now acknowledges it “stretches me out, helps with my balance, and helps with my attitude.”

Perhaps most importantly, Orville changed his diet.

“I lived on junk food,” he admits. "Fat, fried, and greasy food. Red fatty meat. White bread. Candy bars every day."

Now, Orville said he fills his plate with fresh fruit and vegetables. He drinks acai shakes and carrot juice and eats tomatoes and kale.

“I've got so that I really like kale, which is something I thought I'd never say in my life."

Orville said those lifestyle changes -- especially his diet revolution -- improved his physical and mental health and reduced his pain, allowing him to cut back on tramadol, and use it sparingly, for only the worst pain.

Data reviewed by NBC 7 Investigates shows thousands of other San Diegans are also kicking the opioid habit.

According to DEA statistics:

• Oxycodone sales in San Diego have declined every year, since their peak in 2012.
• Hydrocodone use has trended down slowly since 2011, with a significant drop in 2016.

Dr. Roneet Lev, an emergency room physician and pain medication expert at Scripps Mercy hospital, said those stats represent a significant improvement.

“Hydrocodone was the number one prescribed medication in the entire United States,” she said. “More than blood pressure medicines, cholesterol medications, diabetes medications. More than anything by far was hydrocodone."

According to Dr. Lev, prescription opioid use spiked ten years ago, in response to well-funded campaigns by pharmaceutical companies, a lack of knowledge about the potential for abuse, and misguided medical education. She said medical students were taught if “somebody cut their thumb and they had a little boo-boo, (aspiring doctors) are not there to judge their pain. If they say they're in pain, they deserve prescriptions."

Data from the San Diego County Medical Examiner shows from 2006 to 2011, overdose deaths from prescription opiates climbed steadily in San Diego, from 180 deaths in 2006 to 273 deaths in 2011.

Details about those deaths are available on the state of California’s Opioid Overdose Surveillance Dashboard. 

According to the interactive website, in San Diego County:

• Whites and Native Americans have the highest rates of deadly overdoses, while Asians are consistently the least impacted.
• Prescription opioid users ages 55 to 59 are the most likely to overdose.
• Women get more opiate prescriptions than men, but men are much more likely to die of opiate abuse.

“What turned it around was the huge number of people that were dying,” Dr. Lev said of the impetus to reduce the use of prescription opioids.

That effort includes educating doctors and dentists about the importance of limiting the number of pills they give patients, and the use of a statewide database, called “C.U.R.E.S”., to help stop patients from “doctor shopping”.

The DEA also requires doctors to write opioid prescriptions on forgery-resistant forms. In addition, no refills are allowed for the most powerful opioids, so patients must visit their doctor every time they want more pills and doctors’ offices can not phone in prescriptions to pharmacies like they do for other prescription medications.

“If you work in a doctor’s office, maybe at the front desk, you might know what to say to a pharmacy to call in a prescription,” said DEA agent Amy Roderick. “And this will stop that kind of fraud."

Despite these attempts to reduce prescription opioid abuse, Dr. Lev said some patients push back, and even threaten to get their drugs somewhere else.

“They’ll say, ‘I need these medications. I need them to survive, and if you do not give me my pain prescriptions and my medications, then I'll go on to be a heroin addict, and it will be your fault!'"

Data reviewed by NBC 7 Investigates shows as opioids have become harder to get, heroin overdose deaths have increased. Dr. Lev and the county medical examiner's both said the increase in heroin deaths is due more to the cost, potency, and supply of that illegal and powerful narcotic, than to the crackdown on opioid prescribing.

This series of line charts shows the overall overdoses as well as breaks it down by types of drugs.

Sales of hydrocodone, the opioid in Vicodin, have fallen sharply in much of the Northeast, the upper Midwest and Texas in the past five years – a result, perhaps, of the concerted effort by health care workers and regulators to prevent addiction and overdoses. At the same time, however, sales of the drug have risen in broad V stretching from Michigan to Louisiana back north to the Dakota oil fields. Parts of the West are also seeing a spike in sales.

Retail sales of oxycodone, the opioid in OxyContin and Percocet, rose in the past five years in the Plains and much of the South and Rocky Mountain West while declining elsewhere in the U.S. Public health authorities have tried to discourage use of the drug to prevent fatal overdoses. After rising rapidly for a decade, the death toll for natural and semisynthetic opioids such as oxycodone and hydrocodone has stabilized in the past five years while deaths from heroin and synthetic opioids such as fentanyl have soared.

Construction started Wednesday at the San Diego International Airport to expand the Federal Inspection Station at Terminal 2.

The expansion is to accommodate the growing number of international passengers, according to April Boling, San Diego Diego International Airport Authority Board Chairman.

In 1990, the airport only saw around 50,000 international passengers.

Now, there are about 300,000 international passengers coming to San Diego a year, Boling told NBC 7. 

She said that's expected to increase in the next 10 years.

The number of international flights at the airport will be directly impacted by the new inspection station, as it will be more efficient, Boling added.

“Because how rapidly you can move people through it is going to have an impact on the demand for the use of their air carrier,” she said.

The airport also added non-stop flights to Germany this month, and is planning to add direct flights to Switzerland next month.

“It could become a lot busier and it will depend, in part, on how much the community, internationally and locally, supports the existing flights that we have," Boling added. "But we could well double amount of international travelers that have within the next 10 years.”

International flights also generate about $432 million a year for our local economy.

“International travelers, as they come in to San Diego, spend far more than domestic travelers do," Boling told NBC 7. "And so they are really feeding the economy and feeding jobs here. And the flip side of that is that, it makes it easier for residents of the County of San Diego to actually see loved ones and visit other places.”

Boling added that the new inspection station would also add permanent, good paying jobs in San Diego.

A jury on Wednesday acquitted the white Tulsa, Oklahoma, police officer who was charged with manslaughter in the shooting death of an unarmed black man last year, NBC News reported.

Officer Betty Shelby fatally shot Terence Crutcher in Sept. 2016 during an encounter that began with a stalled vehicle in the road.

Shelby's attorney, who had called attention to the fact that Crutcher was on hallucinogenic drugs during the encounter, said the officer is "elated" by the jury's decision.

Crutcher's family, who had stressed that he had his hands up and was not aggressive in the encounter, expressed disappointment after the verdict.

There have certainly been far more exciting games at Petco Park. Wednesday night the Padres dropped game three against the Milwaukee Brewers 3-1. The Brewers lead the four game set 2-1.

There were some bright spots for the Friars. Jhoulys Chacin got the start on the mound for the Padres and had solid game. The righty allowed only two hits and one run in seven innings of work. He finished the night with eight strikeouts. In the fifth inning left fielder Allen Cordoba hit his first career triple.

Milwaukee got on the board early off an RBI single to center field by third baseman Travis Shaw which scored Eric Sogard. San Diego tied it up in the sixth inning when infielder Yangervis Solarte double to center and brought in Wil Myers. That concludes the Padres scoring for the evening.

The Brewers scored twice in the ninth to secure the victory. The final game in this series set is Thursday May 18 at 12:40 p.m. at Petco Park.

A suspected serial thief was caught in Escondido, thanks to the help of a brave bystander. 

San Diego County Sheriff's deputies said 18-year-old Jalen Johnson tried to break in to a home on Corte Merano in Escondido.

Right after, Johnson took off down the street but he was tackled and held down by a Good Samaritan until deputies arrived.

Detectives told NBC 7, Johnson is linked to several burglaries, including one in Vista, another in Escondido and four in San Marcos.

Surveillance cameras at Pedro Flores' home captured the break-in next door in San Marcos on January 23. 

"The first window--it was cracked open and everything, papers everywhere," said Sujey Hernandez, who lives in that home. "I saw all the papers and everything on the floor, and the window was cracked too and I was just like ‘what is this, what is happening?'"

After calling police, Hernandez's mother checked with Flores, and was stunned at what the cameras caught.

Flores and Hernandez found out Wednesday from NBC 7 that the suspect has been arrested with the help of a Good Samaritan.

"I mean, I would've done the same thing if I was home. That kind of people, we don't need in our neighborhood," said Flores. 

"I'm glad they caught him though," Hernandez added. "It makes me feel better now, for other people as well, not just for me."

Investigators told NBC 7, Johnson is from Los Angeles.

It’s unclear why he was targeting homes in North County. 

A San Diego mom’s life was lost in a tragic turn of events after dinner with family in the Central Valley.

Ana Zuniga turned 27-years-old on May 6. Just one week later, on May 13, her family and friends’ happiness turned to heartache.

“Family is everything to me and my family has been torn apart," said Roger Flores, a close family friend of Zuniga.

Zuniga, a single mother of five children, was killed in a drunk driving crash after leaving dinner with her family in Tulare County. Her family left the restaurant in one car--Zuniga ended up riding with Jose Suazo.

According to the California Highway Patrol (CHP), Suazo was driving under the influence on Highway 99 when he veered off the road and slammed into some farm equipment.

Zuniga died after she was ejected from the car.

“She left behind five beautiful angels,” Flores said through tears.

Flores and his fiancé Yvette Magana have taken in Zuniga's children, all between the ages two to 11-year-old.

They say it’s been tough explaining to the children what happened to their mom.

“When they see a picture of her, they say 'Mommy! Mommy!' And it’s  hard for us to stay strong," Flores said.

Flores and his fiancé said they are vowing to keep Zuniga's spirit alive for her children.

Magana told NBC 7, it was Zuniga's kindness that helped them become friends two years ago.

“Everything about her made me feel completely at home,” she said.

But it's the love Zuniga had for her kids and the compassion she had for others that Magana said she will never forget.

“ I was having a hard time that day and I told her 'Thanks for taking care of me,'" Magana told NBC 7. "She said 'That’s what I do for the people I love.' And I’ll never forget the words she told me.”

An GoFundMe page has been set up to help her children.

Companies are stockpiling bitcoins in preparation of future "ransomware" attacks, which have grown exponentially over the past few years, NBC News reported. 

According to cybersecurity experts and firms, about a third of British companies in 2016 retained a cache of digital monies as part of a strategy to "regain access to important intellectual property or business critical data." 

They keep Bitcoin on hand — which currently exchanges for about $1,800 per unit — because government agencies don't necessarily have a fix for institutions once hackers have taken hold of their files, and its cybercriminals' preferred payment method.

The most recent cyberattack, known as "WannaCry," took hundreds of thousands of computers' data files hostage unless users paid a $300 to $600 ransom via Bitcoin.

A woman was arrested after a late night police chase ended in City Heights.

Vice President Mike Pence is launching a fundraising PAC of his own, the "Great America Committee," to advance his political interests, like helping Republican candidates ahead of the 2018 midterm elections, NBC News reported.

It is the first time a sitting vice president has formed such a separate political arm. The paperwork was filed with the FEC Wednesday.

The PAC will be used to cover the costs of Pence's travel aboard Air Force Two to campaign for his party's candidates around the country.

A source close to the vice president dismissed the notion that the PAC is laying the groundwork for Pence to run for president in 2020: "Don't read into 2020 as anything other than his running for re-election as vice president in 2020 and supporting other candidates."

An Illinois man who fell over a railing at Wrigley Field Tuesday, hitting his head, died a day later at the hospital, authorities said. 

Richard E. Garrity, of Wheaton, was pronounced dead at 3:33 p.m. at Advocate Illinois Masonic Medical Center.

The 48-year-old attended the Chicago Cubs game against the Cincinnati Reds with his wife and colleagues Tuesday night, according to his father, Richard Garrity Sr, the Chicago Tribune reported. Police said Garrity was leaving the ballpark when he fell over the railing at about 11 p.m. and suffered head trauma.

"The thoughts and prayers of our entire organization are with his family during this difficult time," the statement read.

His father told the Tribune Garrity was a lifelong Cubs fan.

An autopsy is scheduled for Thursday.

San Diego’s Sharp Mary Birch Hospital for Women & Newborns is about to hit a milestone: the facility is expecting to soon help deliver its 200,000th baby.

The hospital, located at 3003 Health Center Dr., opened in 1992. Back then, it had 169 beds and was used as a traditional nursery for newborns. Twenty-five years later, it’s considered the largest and most extensive center for women’s health in Southern California.

Each year, the hospital welcomes around 9,400 babies into the world, making the facility the leader in newborn deliveries in San Diego County and in the state of California. The hospital also specializes in neonatal intensive care of little ones, featuring 84 beds in that unit.

Carmen Colombo, chief nursing officer for Sharp Mary Birch, said that despite the hospital’s high volume of births, the staff there strives to make each and every delivery special.

“Every birth is an exciting, special event. So, we do what we do best, which is to make their experience here at Sharp Mary Birch one that’s memorable,” she said.

Over time, Colombo said the hospital traded in the traditional nursery set-up for care that involves a newborn staying close to his or her mother from the very start.

"Really, babies belong with their mom and their families," she said.

If mom and dad need a little bit of rest, the hospital offers an area where babies can go for a short time.

While there have been some changes to the hospital over the past 25 years, the focus has remained the same. From day one, Colombo – who’s been with Sharp since 1997 – said the vision of this hospital was to give families that individualized care.

She said walking the halls of the hospital and catching a glimpse of the excitement in the faces of families who have just welcomed a new baby -- from parents and grandparents, to big brothers and sisters -- is always a wonderful feeling.

“It’s special to that family, and when you know that it's special to that family, and you can see that spark in their eyes and their excitement, it doesn't get old,” she explained. “That’ll never get old.”

She said the hospital expects the 200,000th birth to happen either this Friday or Saturday. No word yet on how that milestone baby will be celebrated.

Facebook has been fined 110 million euros ($122 million) by European regulators for providing "misleading information" about its acquisition of instant messaging service WhatsApp.

The social media giant bought WhatsApp in 2014 for $19 billion. The European Commission, the European Union's executive arm, said that Facebook told it that there was no possibility to establish "reliable automated matching between Facebook users' accounts and WhatsApp users' accounts" that year.

The Commission's issue centers around the U.S. social networking giant linking Facebook accounts to WhatsApp user identities.

But last year, Facebook released an update to its terms of service that raised the possibility of linking accounts from both platforms.

Surveillance video shows an SUV that police say was stolen, crashing through a Philadelphia deli and nearly striking a pregnant clerk. 

In the video, 19-year-old Genesis Dejada Torres, who is 5-months pregnant, and a co-worker are seen sitting behind the counter of the Frankford Deli at Frankford Avenue and Tioga Street around 7:30 p.m. Tuesday. Suddenly, a 2017 Nissan Pathfinder crashed through the wall, causing shelves of merchandise to rain on top of them.

[[422870814, C]]

Miraculously, Torres and three other people in the store escaped serious injury. Torres told NBC10 her unborn baby was not harmed. 

"Really crazy though," she said. "I was so nervous yesterday. Like what the heck happened here?"

Torres said she had sat up at just the right time and avoided a more serious injury.

"If she had been sitting down closer [to the counter] it could have pushed her onto the register," co-worker Israel Maldonado told NBC10.

[[422870894, C]]

Police say an 18-year-old man was behind the wheel of the Pathfinder, which was reported stolen in Philadelphia Monday. The suspect was allegedly driving about 100 mph northbound on Frankford Avenue when he lost control of the vehicle and crashed into several other cars before slamming into the deli.

The driver was arrested at the scene, but police are still searching for other suspects who may have also been inside the stolen vehicle.

As police continue to investigate, Torres is thankful both she and her baby are okay.

"It's like I won the lottery," she said.

Workers say the deli will likely be closed for several more days as they continue to make repairs.

Former President George W. Bush took in a Texas Rangers game in Arlington Wednesday night.

And he had a little fun with a TV camera during the game.

Fox Sports reporter Emily Jones was reporting on Mike Napoli during the game against the Philadelphia Phillies when Bush — once a part owner of the Rangers — slid onscreen behind her to say "Hey."

"My most favorite photo bomb ever!" Jones tweeted afterward.

Equipped with helmets and water bottles, thousands of bicyclists put pedal to pavement Thursday for the annual Bike to Work Day in San Diego.

From Oceanside in San Diego’s North County to San Ysidro in the south, locals left their cars at home and instead rode their bikes to work. All morning, volunteers manning 100 pit stops throughout the county helped provide water, snacks, free T-shirts, encouragement and a little break for bicyclists.

One popular pit stop was in the Morena area, led by Rob Tavakoli, vice president of SportRX, a business specializing in eyewear for bicyclists and athletes. For Tavakoli’s company, Bike to Work Day is the ultimate celebration.

“It’s our Super Bowl, birthday, Christmas, Hanukah – everything put together,” he told NBC 7.

In that area, cyclists were coming through as early as 5 a.m.

Tavakoli said there are many reasons to ride to work not just on Bike to Work Day, but every day.

“It feels good, being one less car out there contributing less carbon emissions, a little bit less dependent on gas – just makes the world a lot better of a place,” he said.

Plus, San Diego’s great weather makes it a prime place to pedal.

“If there was ever a town meant for biking to work, it’s San Diego,” said Tavakoli.

Tavakoli said bicyclists can drop into SportRX’s little pit stop area not just on Bike to Work Day, but seven days a week. The stop is always stocked with water and granola bars.

“We really believe that if you get somewhere on two wheels, it’s better for the world, it’s better for our city,” added Tavakoli. “We want to support it as much as possible. We don’t just talk the talk, we pedal the pedal.”

Other pit stops for riders Thursday offered free bike repairs and tune-ups, as well as live music, photo booths and even complimentary massages.

One of the biggest stops was hosted by the University of California San Diego at Town Square near Gilman Drive and the university’s Price Center. The San Diego Zoo and the City of San Diego Parks and Recreation also hosted their annual pit stop near the carousel at Balboa Park of Park Boulevard.

Bike to Work Day is organized by the San Diego Association of Goverments’ (SANDAG) iCommute program.

At least one person has died and nearly two dozen were hurt when a wrong-way driver slammed into a crowd of pedestrians in Times Square Thursday, senior officials familiar with the investigation tell NBC 4 New York.  

The driver, 26-year-old Richard Rojas of the Bronx, according to multiple law enforcement sources, was taken into custody after barreling into the lunch-hour crowd near 43rd Street and Seventh Avenue shortly before noon. The sources say Rojas, who has a history of DWI arrests and license suspensions, made a wrong turn on Seventh Avenue and started careening down the sidewalk.  

[[422991054, C]]

Fire officials say a total of 20 people, including the person who died, were hit by the vehicle. Four of the survivors were taken to hospitals in critical or serious condition. Sources say the number of victims is expected to rise as law enforcement agencies coordinate their rescue efforts.

A cause of the crash is under investigation, but authorities say it's believed to be an "isolated incident" with no nexus to terror. Law enforcement sources say tests are being conducted to determine if the driver was under the influence of drugs or alcohol at the time of the crash. Sources close to the probe say at this time, that's investigators' leading theory given his history.

In one of his two previous DWI arrests, the suspect was driving faster than 99 mph in a 50 mph zone, sources familiar with his record say.

[[422990554, C]]

Social media erupted with concern as witnesses described screaming and abject chaos in the Crossroads of the World. Someone tweeted a photo of a maroon-looking sedan halfway on its side after appearing to crash into a traffic pole. Smoke emanated from the hood as pedestrians stood by in horror.

Police radio captured the urgency of the response.

"Times Square, we got a car running people over on 42-7, going northbound on 7th ave, running people over," one NYPD dispatcher said, according to audio clips from Broadcastify. "Multiple people injured. Notify everyone."   

[[238427591, C]]

Witnesses said the vehicle was speeding -- one said up to 80 mph -- at the time of the crash. Live traffic cameras showed a gigantic emergency response in the area; at least five fire trucks cordoned off the intersection immediately near the scene and a line of police cruises, alarms and lights blaring, blocked off traffic near the TKTS booth.

Mayor de Blasio and Gov. Cuomo both tweeted they were headed to the scene.

Police arrested a man accused of filming a teen girl and then attacking and tying her up at knifepoint inside the bathroom of a Barnes and Noble store in Berks County, Pennsylvania. 

The 14-year-old girl told police she was visiting the Barnes and Noble in the Broadcasting Square shopping center in Wyomissing with her boyfriend and his mother around 8 p.m. Tuesday. The girl said she entered the women’s restroom inside the store and noticed a man holding a cellphone over the top of the bathroom stall she was in. The girl told investigators she believed the man was using it to photograph or record her.

Police say the man then attacked the girl as she walked out of the stall. He allegedly forced her at knifepoint into another stall, threatened her and bound her with zip ties. The girl struggled with the suspect, causing him to cut himself with the knife and bleed, police said.

The girl told investigators the man continued to hold her inside the stall while he bled on the floor, but eventually agreed to cut the ties from her wrists. The girl said her boyfriend’s mother then went into the bathroom to check on her and she broke free from his hold. The suspect then fled out of the bathroom, police said.

Responding officers apprehended the suspect who they identified as Dustin Cornelius, 19, of Richland, Pennsylvania. Police found him in possession of the knife and they also recovered his cellphone and zip ties. Cornelius was treated for a cut at a local hospital and committed to the Berks County Prison after failing to post bail.

Cornelius was charged with unlawful restraint, false imprisonment, simple assault and harassment. 

The girl told police she had never seen or met Cornelius prior to the incident.

Rolls Royce Corp. will perform up to $4.7 million worth of work at Marine Corps Air Station Miramar for its other business — aircraft engines.

The company will provide engineering and logistics support for the engines on the KC-130J aircraft flown by the U.S. Marine Corps under a recently awarded U.S. Navy contract.

The deal is for five years.

The military has several uses for Lockheed Martin Corp.’s C-130 Hercules transport aircraft, which dates from the 1950s. The U.S. Marine Corps uses its KC-130J aircraft as aerial refueling tankers.

The propeller-driven aircraft has four Rolls Royce AE2100D3 engines.

The $4.7 million makes up 6 percent of a wider, $78.7 million contract. The bulk of the work — 75 percent — will be done at Rolls Royce’s facility in Indianapolis.

Rolls Royce must now wait for the Navy to issue task orders under the indefinite-delivery, indefinite-quantity deal.

The Naval Air Systems Command at Patuxent River, Md. awarded the contract, which the Pentagon announced on May 9. The contract was not competitively procured.
