NEW YORK (CBSNewYork) — One teenage boy is dead and one was left in critical condition after they fell from a roof in Bushwick, Brooklyn Friday.

As CBS2’s Jessica Layton reported, police said the teens fell 50 feet from an apartment building at 57 Grove St. in Brooklyn just before 6 p.m.

One of the boys, 13, was pronounced dead at NYC Health + Hospitals/Kings County. He suffered severe trauma to his head and body, police said.

Police have identified the deceased teenager as Rame Pierre-Louis of Brooklyn.

The other boy, 15, suffered injuries to his pelvis and was conscious and alert at the hospital late Friday, police said.

It is believed the teens were jumping from building to building and fell from the roof, sources said.

“I’ve never heard of someone trying to jump off my building,” said Nasir Brown.

Brown was feeling numb Friday night after learning the two teens – whom he frequently looks out — had fallen off the roof of his three-story apartment building into the back courtyard.

“I don’t know if they were play-fighting and one ended up tussling over, or if they were are actually trying play and like to dare each other to jump over,” Brown said. 

Anyone who heard the fall from the building described the same sound.

“I just came home from work, and we just heard this loud thud; like two thuds right after another,” said Albert Mathew.

“It sounded like a refrigerator hit the floor. When they hit the floor, we came out, thought it was my landlord pushing something out,” a man, who didn’t want to be identified, told 1010 WINS’ Andrew Falzone. The man used to work in the building as a superintendent and said neither of the boys lived there.

Tenants said the ambulance arrived in minutes to rush the boys to the hospital. But the New York City Medical Examiner’s office arrived on the scene soon afterward upon revelations that the boy did not survive.

“I just try to warn them, and they’re just kids,” Brown said. “I did not think they would take it to that level.”

Neighbor said the building has been the site of a lot of problems, specifically teens going to the roof to party and horse around. But they were heartbroken for the families of the teens involved.

“These kids don’t belong on this roof. They’re not from this block at all. They just go there to smoke, drink and mess around in the building,” one man said. “This is a problem that everybody in the building’s having.”

The teens’ names have not been released.
