The suspected gunman who wounded an innocent teen bystander outside a Queens school turned himself in on Tuesday — and cops believe the shooting is linked to another just two days earlier, sources said.

The identity of the alleged shooter was not immediately released, but a high-ranking police source said he surrendered at the 113th Precinct station house in connection to the incident outside New Dawn Charter School II in Jamaica on Monday.
Law enforcement sources said the intended target in that shooting — a 16-year-old boy — is believed to have been targeted in a separate incident on Saturday at Baisley Park Houses about two miles away.
Aamir “Buddy” Griffin, 14, was struck and killed by a stray bullet fired from more than 100 yards away at the NYCHA housing complex.
Meanwhile, a 16-year-old girl was hit in the left shoulder after a group of teens jumped a 16-year-old boy just before 4 p.m. at the charter school.

She was transported to Long Island Jewish Medical Center in stable condition. No firearm was recovered from the scene.
Police plan to transfer the suspect to the 103rd Precinct station house, which is the precinct where the school shooting occurred, according to the source.
