It is frustrating when an airline loses your luggage. NBC10 Responds Reporter Harry Hairston has tips on what to do if this ever happens to you.

A local police department is using a groundbreaking system that allows 911 callers to send live videos to dispatchers. The goal is to improve how emergency responses are handled.

As the opioid crisis continues to impact the nation, officials at the Camden County jail announced the expansion of a program that's helping inmates beat addiction.

A murder mystery is unfolding in a New Jersey neighborhood. A body was found on a backyard deck in an East Windsor home. Homicide investigators are trying to find out how and why this person was killed.

The jobs of Philadelphia EMS technicians and paramedics are among the busiest and most stressful in the city. Jeremiah Laster, a deputy chief with the Philadelphia Fire Department, gave NBC10 an insider's look at a day in the life saving lives in America's sixth-largest city.

At least 20 cars were involved in a wreck that closed busy Route 309 in Montgomery County for several hours Thursday morning. There appeared to be some ice on the roadway but police didn't say what caused the pileup.

The cars, many with the lights still on, backed up above the Susquehanna Road overpass of both the northbound and southbound lanes of Route 309 in Upper Dublin Township. The initial crash happened around 6 a.m. in the northbound lanes, Montgomery County dispatchers said.

At least six people were transported from the scene, dispatchers said. The extent of injuries isn’t clear and no fatalities were reported.

It’s possible that there was some ice on the highway as police appeared to be slipping while investigating the crash. Some light snow also moved through the area overnight. Salt trucks were brought in to treat the roadway.

Though both the southbound and northbound lanes reopened a little after 8 a.m., traffic was backed up for a long distance in both directions.

Avoid the area and seek alternate routes like Limekiln and Bethlehem pikes. The Northeast Extension of the Pennsylvania Turnpike can be used if you are going a longer distance.

Police have arrested a postal employee in New Jersey for allegedly running over two other postal workers in the parking lot after an argument. 

Kearny Police said they got a 911 call around noon for a report of a driver running over two people in the parking lot of the USPS office on Newark Turnpike. Responding officers found two women, ages 25 and 26, injured but conscious in the parking lot. 

The women told police that a third colleague hit them with her car -- one of them being run over and the other being hit by the car and knocked down, they said. The driver fled before police got there. 

Both victims were taken to University Hospital in Newark by EMS, and one was released. 

Police and U.S. postal inspectors located the suspect, 27-year-old Lashanda Johnson of East Orange, and arrested her on aggravated assault and other charges.

Attorney information for Johnson wasn't immediately available. In a statement, George Flood, a spokesman for the U.S. Postal Service Northeast Area said, "The Postal Service takes seriously the safety and security of its employees. Given the pending criminal charges, we do not discuss personnel actions." 

March is expected to come in like a lion at the worst time as snow hits early Friday, possibly causing for a slick morning commute.

A First Alert for periods of steady snow and slippery surfaces will be in effect for most neighborhoods from 4 to 11 a.m. Friday.

What to Expect:

This isn't expected to be a major winter storm but an inch or more of snow could fall across most neighborhoods causing a nuisance for the morning drive or ride. The snow is expected to move into the region after midnight and move out by late morning. Most of the snow should fall before daybreak.

It should be cold enough for the snow to accumulate, with 1 to 3 inches expected for many neighborhoods, including Philadelphia, northern Delaware, Berks County and most of South Jersey and the Pennsylvania suburbs. A coating to an inch is expected in the upper Pennsylvania suburbs, Lehigh Valley, Mercer County, southernmost New Jersey and southern Delaware.

Crews should be able to treat major roads ahead of the storm but side roads and sidewalks could be slippery. DelDOT was already brining roads under clear skies Thursday.

Plan to give yourself extra time to brush off your car or walk to your train or bus. It's possible schools could have delayed openings so be sure to be signed up for School Closings alerts.

Once the snow leaves, temps only warm slightly with highs expected in the low 40s.

Weekend Rain/Wintry Mix:

More wet weather is expected over the weekend but this time it should just be rain in some neighborhoods with a wintry mix and/or snow in colder areas.

Scattered showers are expected Friday night into Saturday morning with another chance of rain during the day.

More rain and a wintry mix or snow then moves in Sunday afternoon into evening. Neighborhoods to the north are more likely to get some wintry weather rather than rain.

Basketball's most energetic team (excluding the Sixers, of course) is making the most of their visit to Philadelphia.

The Harlem Globetrotters will play in Allentown Thursday night, at Temple University's Liacouras Center Friday and the Wells Fargo Center Sunday, as well as making stops in Trenton and Atlantic City.

Before that, Darnell "Speedy" Artis, a Philadelphia native, returned to the Lonnie Young Recreation Center in Germantown to shoot some hoops in his old neighborhood. 

"This is where I became a basketball player," Artis told NBC10. "To be here as a Harlem Globetrotter is just a dream come true."

Artis and Julian "Zeus" McClurkin also paid a joint visit to Radnor Elementary school, where they surprised 7-year-old Dylan Sari. Dylan is battling leukemia and is in chemotherapy.

The players said they were inspired to visit the school after Dylan's mother sent them a letter calling the first grader "a huge fan of the Globetrotters." He and his classmates were treated to a close look at some of the ballers' famous tricks.

McClurkin also visited the AtlantiCare Regional Medical Center Wednesday. During his visit, McClurkin met with pediatrics and adult patients, their families, and the facility's staff members. 

Some members of the team even found time to hop off the court and into the tank at Camden's Adventure Aquarium. Artis and McClurkin were joined by fellow teammate Briana "Hoops" Green as they braved the water for a swim with sharks and sting rays.

Superstar outfielder Bryce Harper has made his choice — and it's the Phillies.

NBC Sports Philadelphia reports that the former longtime Washington National is switching to the inter-division rival, Phillies.

Details of the deal are not yet known, but several Major League Baseball national reporters have tweeted that the deal is worth $330 million over 13 years. That price tag would make it the most expensive player contract in history.

Harper was the biggest catch of the baseball offseason. He spent the last few months trying to secure a mega-contract worth in excess of $300 million. He played for the Nationals his entire career, after being drafted first overall in 2010 as a five-tool prodigy.

• How Nolan Arenado's Mega-Deal Affects Bryce Harper Negotiations

— Jim Salisbury (@JSalisburyNBCS) February 28, 2019

The Nationals gave up on re-signing Harper in recent months, and the move to Philadelphia would reshape the power structure in the National League East. In recent years, the Nationals had won four of the last seven NL East division championships.

Harper Mania had enveloped Philadelphia's rabid sports fans in recent weeks. He joins a Phillies team expected to be much improved this upcoming season.

The All-Star slugger, who's been named everything from the National League's Most Valuable Player to the NL Rookie of the Year to the Silver Slugger, has a career .279 batting average with 184 home runs, with a .388 on-base percentage.

Phillies principal owner John Middleton had made it clear that the team was willing to pay what was needed to land Harper or the other big fish of baseball's free agency, Manny Machado.

Machado signed earlier in February with the San Diego Padres. His contract is reportedly $300 million over 10 years. Harper's reported contract is $5 million richer than Yankees slugger Giancarlo Stanton's $325 million contract that he signed three years ago with the Miami Marlins.

Harper's is the largest of three mega-deals signed this offseason. The Colorado Rockies re-signed their star third basemen Nolan Arenado to a $260 million deal.

Parents in a South Jersey community are reeling. They say their children’s small private school in Barrington shut its doors with less than 24-hours’ notice. Now they’re scrambling to figure out where their kids will find a new place to learn.

The man accused of raping several women in South Philadelphia is infected with HIV, NBC10 confirmed.

Safien Williams, a Philadelphia Streets Department employee, was charged Tuesday with three rapes and an indecent assault in the Point Breeze neighborhood.

The rapes occured on Mifflin and Bancroft streets and the assault on South 16th Street. In May 2018, another woman was raped on Morris Street. 

In each case, Williams, 37, followed the women during late-night or early-morning hours to their homes or places of business, investigators said.

Philadelphia Police Commissioner Richard Ross called Williams a "very violent predator who essentially terrorized an entire neighborhood."

Police fear additional victims have yet to come forward and encouraged people report assaults, regardless of their immigration status.

The Philadelphia Police Department, however, and the Philadelphia District Attorney's Office did not comment on Williams' health status. 

The city's health department also would not comment on Williams' status, but said in a statement that "all the victims who have come forward are being offered the appropriate counseling and medical care."

"We urge anyone who has been the victim of sexual assault to seek the proper medical care," a spokesman for the Philadelphia Department of Public Health said in an emailed statement.

HIV is spread through blood, semen, breast milk and other bodily fluids. Sharing needles or having unprotected anal sex puts people at especially high risk of infection.

About 19,000 people are currently living with HIV in Philadelphia, according to Dr. Sara Schultz, an infectious disease specialist at Drexel University College of Medicine. People who think they might have been exposed to the virus should seek medical attention immediately.

"After a sexual assault, it is unlikely but possible to transmit HIV depending on various factors ... including how much HIV [the attacker] had," Schultz said. 

If an HIV patient's status is undectable, then transmission is less likely, she added. But if someone with HIV is not on medication, has not been diagnosed or very recently contracted HIV, then the transmission risk increases. 

"Time is of the essence," Schultz said. 

Advances in medicine have made it possible for people exposed to the virus to drastically reduce their risk of transmission by taking a medication every day for 28 days. Nonoccupational postexposure prophylaxis, or nPEP, is most effective when taken within 72 hours. 

"The sooner this is started after an assault, the better," she said.

A suspect is in custody and three people are recovering after a DUI driver crashed into two vehicles, including a police car, investigators said.

The unidentified driver struck the two vehicles on Custer and Clearfield streets in Philadelphia's Kensington neighborhood shortly before 8 p.m. Thursday. No officers were hurt but three people suffered minor injuries.

The suspect was taken into custody for DUI. Officials have not yet revealed his or her identity.

Family members say the body of a Massachusetts woman who was last seen at a Boston nightclub on Saturday night has been found in the trunk of a car in Delaware, where her alleged kidnapper was captured on Thursday. 

"We received some devastating news today and Jassy is no longer with us," Kathia Depina, the cousin of Jassy Correia said on Thursday night. 

A Rhode Island man wanted in connection with the kidnapping of 23-year-old Jassy Correia of Lynn was taken into custody Thursday in Delaware, according to law enforcement sources. Boston Police said a body had been recovered and they were awaiting positive identification.

Thirty-two-year-old Providence resident Louis D. Coleman III had been wanted in connection with the kidnapping of Correia. Providence Police said that Coleman was apprehended in Delaware and that a body was found in the trunk of his vehicle.

Earlier in the day, Joel Correia told NBC10 Boston that his sister Jassy was dead.

Depina said she received news from police on Thursday that the body was identified as Correia.

"She was a mother, she was brave, she was strong. She did not deserve this. She went out to celebrate her birthday and never returned home. She did not deserve this," she said. "We want justice for her death."

"Women should have the right to go to any nightclub and wear what they want and not worry about being kidnapped and murdered at the end of their night," said family friend Joao Depina.

Family and friends say they've never heard of Coleman and don't think Correia knew him, either.

Authorities said Coleman had previously been seen in the Providence area on Thursday. A search warrant was conducted at his Chestnut Street apartment, but Providence Police Chief Hugh Clements said he could not give details on what was found.

Clements said the case was being treated as a homicide investigation. He said police in Providence and Boston are investigating in collaboration with the Rhode Island Attorney General's Office and the U.S. Attorney General's Office, as well as local offices of the FBI.

"We don't know right now whether it will be Boston, Providence or a federal agency who eventually takes the case," Clements said.

Correia, the mother of a 2-year-old girl, told her family she was going out on Saturday night and didn't respond to messages on Sunday, Monday or Tuesday, which is when her family began to fear the worst.

She was last seen leaving Venu Nightclub in Boston just after midnight on Sunday, getting into a red car with a man, believed to be Coleman, near Tremont Street and Herald Street. The family could not reach her on her birthday on Tuesday, and she was reported missing Wednesday.

You've probably seen the terrifying nightmare fuel: a woman's face elongated into a beak, with bug eyes and stringy black hair.

You might have seen it shared on Facebook with a warning from parents or local police, accompanied by the scary story that some kids have been sent the image with a challenge to take drugs, hurt or even kill themselves. And you've seen coverage of those police warnings on NBC10 and other local news stations.

But is the Momo Challenge real? And is it something you need to be concerned about?

Under all the hype, it's hard to find any proof that the "challenge" is more than an urban legend. But that image has gotten plenty of attention, and it has frightened some kids.

In the latest round of coverage, some parents claimed on social media that Momo messages were being inserted into children's videos on YouTube, including Peppa Pig and Fortnight videos.

This led Kim Kardashian West to take to her Instagram story Tuesday with a plea asking YouTube to help. "Parents please be aware and very cautious of what your child watches on YouTube and KIDS YOUTUBE," she said.

Kardashian West's Instagram has more than 129 million followers. It didn't take long for YouTube to issue a response. The company said they had seen no evidence of the challenge on its site.

YouTube also noted that anything that encourages self-harm violates the platform's policies and "would be removed immediately."

The Atlantic and fact-checking website Snopes have both looked into the Momo challenge. They found no evidence that Momo pops up in Peppa Pig and found no evidence the Momo challenge has led anyone to harm themselves or to kill themselves.

Despite reports of suicides, the Today show reported that so far, no law enforcement officials have reported any injuries or deaths related to the so-called challenge. 

But here's where things get complicated, especially for parents. Just as scary urban legends have spread at sleepovers long before the internet began (Bloody Mary, anyone?), the "Momo" image is something that many kids have heard about -- and may have seen.

NBC10 spoke to a young New Jersey boy who was sent the photo by a classmate. The Cape May Police Department had enough concerned parents reaching out that they posted a Facebook message to parents warning, "This 'game' is believed to be a way for people to hack accounts and is psychologically manipulative towards kids and teens."

Local police in Gloucester, Massachusetts posted a similar warning Tuesday. A mom in Lowell told the local NBC station that her 10-year-old had seen the image.

"I said, 'Evan, do you know who this is?'" the mom said. "And he said, 'Don’t show me. Don’t show me.' He knew exactly who it was. He had seen it before."

Just this week, Today interviewed a mom who said her three-year-old knew that Momo was the "scary lady" with "big eyes, long black hair and a white face."

The Momo image is actually a cropped photo of a sculpture created by the artist Keisuke Aisawa for Japanese special-effects company Link Factory, the Atlantic reported. It's called "Mother Bird" and was displayed at a Tokyo gallery that specializes in horror art in 2016.

Someone snapped photos for Instagram, a Reddit called "Creepy" picked them up -- and Momo was born, ready to alarm parents and get shared around by teens.

Even if Momo is more viral than vicious, the picture can be scary.

Meghan Walls, a pediatric psychologist, told NBC10 that parents should take preemptive action and gently ask their younger children if they know about the image.

"Say something like, 'There's some scary things that pop up on phones and tablets, and if you ever see something like that, come get me,'" Walls said.
