After 36 hours of searching by more than 100 members of law enforcement and with the assistance of local FBI agents, authorities found a missing Atlantic County teenager with autism, huddled next to a tree in the cold.

Joel Medina, a 17-year-old with autism, first went missing on Friday afternoon after he left his home in Egg Harbor Township.

It took more than 100 officers from about a dozen agencies and the FBI to find the teenager in a marshy wooded area shivering from the cold temperatures.

Egg Harbor Township police initially issued a call for any information about Medina’s whereabouts on Friday at 3:38 p.m. in a social media post after he left his home in the area of 4th Avenue behind the Shore Mall, authorities said.

Later Friday night, authorities asked the public to submit home surveillance and doorbell recordings that may have recorded Medina walking by to help track down leads.

Officials from the Egg Harbor Township Police Department, neighboring police departments, EMS personnel, county sheriff departments, state and county offices of emergency management, rescue teams from Camden, Gloucester and Cumberland Counties and helicopters from the Coast Guard searched for Medina, officials said.

By Saturday morning at about 10 a.m., authorities had still not located Medina and were searching the wooded areas around his home, officials said.

The search included drones, infrared technology, water searches and the use of bloodhounds, officials said.

Residents in the area were asked to stay out of the woods Saturday night as authorities continued searching for Medina using Forward Looking Infrared technology attached to a plane flown by the FBI, officials said.

Medina was located in the woods early Sunday morning at about 1:30 a.m., officials said.

Body-worn camera footage from responding officers showed rescuers crawling through thick and dense brush to reach Medina who asked for his mom and dad after authorities reached him. The FBI’s Newark office also released footage taken as rescuers found Medina.

At least one officer gave Medina his coat and sweatshirt before the rescue team guided him out of the woods, according to the recordings.

Medina was taken to an area hospital to be medically evaluated, Egg Harbor Township Police Chief Frederick Spano said.

The FBI’s aircraft was a crucial piece of equipment in locating Medina, but the cooperation among more than 100 personnel from different agencies — who scanned the woods for almost two days and never gave up — deserved the gratitude, Spano said.

“Thank you to everyone that never quit, never lost hope and assisted with this happy ending,” a post from the police department said on Sunday morning.

A spokesperson for the FBI did not respond to a request for comment.
