The body of a missing Long Island teen was found floating in Brooklyn waters more than two months after he mysteriously vanished in New York City, police said.

Thomas Medlin’s body was positively identified Thursday, Suffolk County police announced, after it was recovered in the waters off of Red Hook on Saturday.

The 15-year-old was last seen on surveillance footage walking across the Manhattan Bridge in early January on the night he went missing, just moments before the cameras caught an ominous splash in the East River — with the boy never seen in the footage walking off the platform, officials previously said.

Medlin first vanished on the afternoon of Jan. 9 after leaving his prestigious Suffolk County private school unnoticed and catching a train to Grand Central Terminal, where he was first spotted on security cameras, police said.

Cameras then captured the teen on the pedestrian walkway on the Manhattan Bridge at 7:06 p.m. the same day — with his last mobile phone activity recorded at 7:09 p.m. as the splash in the water was caught at 7:10 p.m.

Medlin’s family had previously suspected foul play, and that their child may have fled to the city to meet with a stranger he met on Roblox, sparking a massive citywide search.

But police later debunked that theory, and have said “there is no indication of criminal activity.”
