State environmental officials say there is no indication of disease, and that the fish, which normally produce in large numbers and consume a lot of oxygen, simply overproduced.

Belmar Mayor Matt Doherty says crews will be patrolling the beaches this weekend to clear any dead fish out of the way of beachgoers.

The first transformer exploded around 3 a.m. Friday at 15th and Market Streets in Center City.

• Worker Slips, Falls Into Manhole

As officers investigated the first blast, they saw the second one occur at 15th and Market. After the manhole cover blew off, smoke could be seen coming from the hole, according to officers on the scene.

Philadelphia Firefighters got the situation under control after about an hour. And PECO crews were on the scene since they own the two transformers that caught fire.

Luckily no one was hurt.

Police blocked off the intersection and surrounding roads and sidewalks as the investigation continued. SEPTA also detoured buses around the scene and the trolley lines were bypassing the 15th Street stop.

Those restrictions were slowly lifted and by 5:15 a.m. traffic was getting by on Market Street and some lanes along 15th Street near City Hall. The incident was mostly cleared by the morning rush.

The preliminary hearing for Francis Laurenzi scheduled for Friday morning however was postponed.

• Students Expelled Over Upskirt Video of Their Teacher

Laurenzi, 28, has remained in county jail since his May 7 arrest unable to post 10 percent of $100,000 bail, according to court records.

The dance teacher's accuser contacted Limerick Township Police to report a sexual relationship she said she had with Laurenzi from August 2012 until March 2014, according to police records.

• EARLIER COVERAGE: Dance Teacher, Teen Had 2-Year Relationship: Police

The victim told police the encounters occurred at the Urban Elegance Dance Club at 110 Fayette St., Conshohocken -- one of the two dance studios where Laurenzi taught, according to the police affidavit.

Official documents also show she emailed the suspect at least 25 nude photos of herself and the pair exchanged text messages.

One text Laurenzi sent the teen reads: "I felt an attraction between us...Are we going to do anything about it?"

Laurenzi faces multiple charges including statutory rape, indecent assault, possession of child pornography and manufacturing of child pornography.

The suspect also taught at the LeRoux School of Dance at 301 N. Lewis Rd., Limerick Township, according to police. Both schools offer classes to adults and children, some as young as 18 months old.

Laurenzi stopped working at LeRoux about a year ago, according to a statement from the studio's owner.

• Shore Town Makes Best Beaches for Swimming List

"While Mr. Laurenzi was a teacher at LeRoux School of Dance in the past, he taught group classes and did not have one on one lessons through our school," said Kelly Stento, owner and director, in a statement. "There was never anything in Mr. Laurenzi's background that would indicate a predilection to the type of alleged behavior. Again, we are deeply saddened and distressed by the reports received but the actions alleged were not related to this school."

Leaders with Urban Elegance did not return earlier calls requesting comment.

No new date was immediately set for Laurenzi's preliminary hearing.

Police ask anyone with information about other incidents involving Laurenzi to contact the Conshohocken Police Department at 610-8258-4032 or the Limerick Township Police Department at 610-495-7909.

"The rain is tapering off," said NBC10 First Alert Chief Meteorologist Glenn "Hurricane" Schwartz. "It is going to end from west to east over the next six to eight hours."

Even though the worst of the storm has ended, the light rainfall will continue to drive totals up, which means flooding remains a concern, Schwartz added.

An 8-year-old western Pennsylvania girl is recovering after a driver fleeing police sent a parked car careening into her as she rode her scooter, in a horrifying crash caught on surveillance video.

• Cops didn't have to go very far to make this DUI arrest

But even as Cassidy Wall recovers, that video still upsets her, she says.

"When I saw the video, every time I thought about it, I started crying," she said. "It hurted my feelings, and I didn’t like what I saw."

• This woman took "back to school" to a whole new level

"I fell and flew in the air, and I landed on my head," Cassidy told NBC affiliate WICU.

Cassidy and her 5-year-old sister Zmyiah were playing out front of their home near the corner of East 29th and German Streets in Erie, Pennsylvania, on May 9 when a police pursuit zoomed past.

The fleeing vehicle struck a parked car -- flinging it up onto the sidewalk, where the Cassidy was riding her scooter.

"The car crashed… then she (Cassidy) got hit," Zmyiah -- who was heading down the front steps at the time of the crash and was able to avoid being hit -- told WICU. "She flew all the way up in the sky and fell on her head."

• Woman in Wheelchair Fed Up Being Locked Out

Despite the violent impact, Cassidy only suffered a concussion and was back up  a few days later.

Police eventually caught up to the men they say were in the car at the time, arresting suspected driver Angello Moore and passenger Brandon Carlson.

Moore, 18, was sent to county jail, unable to post $125,000 bail. He faces 22 counts, including fleeing police, aggravated assault by vehicle, reckless endangerment, drug possession and related charges, according to court documents.

Carlson, 18, faces firearm and marijuana charges. He remains jailed, unable to post $20,000 bail, according to online court records.

Surveillance video released earlier this week shows Cassidy being rammed by the out-of-control car.

"I was terrified... I still [am] terrified," Cassidy's father Delorean Wall told WICU. "As a father, you don't want that to happen to your children. It's crazy."

• Police didn't have to go far to make this arrest...

A juvenile and a 32-year-old man, Jebreel Abdullah, were arrested Thursday night for their part in the shooting of a 9-year-old girl last Monday on the 200 block of Bellevue Avenue in Trenton.

The girl was shot three times, according to officials. One bullet struck the girl's shoulder, another grazed her leg and another, her ribs.

"I heard six shots," said Sadie Toney, the girl's neighbor. "This little girl came running up the streets crying. She was holding her arm. I saw blood trickling down her arm. Then she went into my neighbor's house."

• 9-Year-Old Girl Shot 3 Times

The man called 911 and the girl was transported to St. Christopher's Hospital.

Law enforcement sources say the girl was with her stepfather at the time of the shooting. They also say the stepfather, who has not yet been identified, was arrested for charges not related to the shooting.

It took police only a few days for police to arrest the teen and Abdullah for the shooting. Both were arrested at a house on Spring Street in Trenton.

Six others, who were also inside the Spring Street home, were arrested for unrelated outstanding warrants, according to police.

Officials also say they found a large amount of heroin in the home with ammunition, although no weapons were recovered.

A new incubator space at Philadelphia University is driving students, including two seniors set to graduate this weekend, to take the products developed through the school’s hands-on curriculum and leverage them into a business.

"Having a beautiful product is great for a project," said Zoe Selzer McKinley, director of the Blackstone LauchPad program at PhilaU’s Entrepreneurship Center. "But unless you build an entire business around it and understand your customers, it’ll just sit on the shelves."

• Company Targets Philly for High-End Sweatpants

The program began in January thanks to a $3 million grant from the Blackstone Charitable Foundation that established a partnership among Philadelphia University, Temple University and the University City Science Center. The goal is to introduce entrepreneurship as a viable career option and provide the schools’ students and alumni with the resources needed to transform ideas into companies.

Selzer McKinley helps PhilaU students develop a business plan and serves as a networking resource to connect the future entrepreneurs with investors, potential retailers and industry mentors. 

• Woman in Wheelchair Locked Out of Supermarket

“It is a coaching based model,” Selzer McKinley said. “Depending on the individual product and student, we see where they need to go and work with them to progress towards that goal.”

She acknowledges that not every venture will be successful, but students can still learn from failure.

"If they try and it doesn't work, they have done it quickly and efficiently and can move on to something else or pivot their business model," she said.

• Men Admit to Burying Missing NJ Mom Alive: Police

Selzer McKinley's advice – doled out weekly over the past five months – helped industrial design classmates, Colin Hansel of Babylon, N.Y. and Morgan Gaumann of Havertown, both 22, take the handcrafted surfboards and snowboards they refined throughout a year-long capstone class and create a board development company, RodeoBird SurfCraft.

“Industrial design students don’t really have a background in entrepreneurship,” Hansel said. “So it is up to the student to decide whether it is just a product for their portfolio or if it’s more.”

Incubators, like LaunchPad, are an ideal place for Hansel and Gaumann to evaluate if their board could sell since it forces new entrepreneurs to incorporate the business side while creating their product, said Patrick FitzGerald, managing director of DreamIt Philly, a business accelerator program that offers young entrepreneurs funding and guidance.

“Having a safety net in an educational environment certainly allows people to play in a sandbox,” FitzGerald said. “In the real world, that could sometimes be very painful.”

Hansel and Gaumann, who met freshman year, began developing their boards in summer 2013 after connecting over a love for similar sports –surfing and snowboarding.

• Philly Tourism Generates Billions

“We noticed both of the sports are the same in premise although they have kind of diverged from themselves a bit,” said Hansel, who explained many of the first snowboarders were surfers eager to test out their skills on a winter landscape. “We are trying to bring the sports back to center.”

The business partners spent the school year testing materials and rethinking the manufacturing process, eventually leading Hansel and Gaumann to use carbon, kevlar and Innegra in the surfboard’s formation.

“When you weave those together, you get the strength of carbon with the flexibility of Innegra, which is something that hasn’t really been done before,” said Hansel, who made his first surfboard nine years ago. “They give you the ability to engineer your flex patterns, the pattern in the board that allows it to have stability... that can provide you with grip.”

• Hotel, New Businesses Coming to 69th Street

Even though the students knew their board offered surfers another great option, they lacked the knowledge needed to turn their invention into dollars.

“From the start, Zoe broke it down,” Hansel said. “What does this mean to an investor, what does this mean to a customer, what is your cost analysis, and what is the value of the product to the industry?”

The goal-setting sessions pushed them to form RodeoBird SurfCraft and secure a retailer, Garden State Surf and Art, for their boards.  They go on sale at the Beach Haven Crest, N.J. shop Memorial Day weekend.

The partners are currently testing a snowboard prototype and expect to sell their boards online by the end of the summer.

“Ultimately Launchpad made the product and the company stronger,” Hansel said.

• PAST: Men Admit to Burying Missing NJ Mother Alive, Police Say

Speaking from South America, Fatima Perez’s mother-in-law, Birtha Justina Estrada, said she nearly fainted at her home in a rural Nicaraguan village after learning the mother of two had been murdered in such a gruesome way.

“I started yelling,” said Estrada, recalling the phone conversation with her son. “This girl didn’t deserve to die this way because she didn’t have any enemies.”

Perez, a 41-year-old mother of two from Camden, N.J., caught a ride a friend on Monday night to go purchase a car. But over the course of that ride, authorities say she got into an argument with the man, Carlos Alicea-Antonetti, and was injured from falling out of his landscaping van. The woman got back into the van and laid in the back while Alicea-Antonetti went to pick up his employee Ramon Ortiz, police said.

Ortiz allegedly told detectives the men then tied up Perez, covered her mouth with duct tape before they dug a shallow grave in a wooded area of Monroe Township, N.J. The men then covered her with lime and filled the hole. Ortiz said she was still alive when they buried her, according to prosecutors. Perez’s body was discovered two days later.

Estrada said she had last seen her daughter-in-law eight months ago when Perez came to visit and remains upset over her death.

Police have not yet released an official motive, but officials said she was carrying $8,000 when she left to purchase the car. Detectives said they found about $7,000 in cash on Alicea-Antonetti when he was taken into custody.

Alicea-Antonetti and Ortiz are being held on $5 million cash bail.
