A person of interest is in custody Tuesday in connection to a shooting that struck and injured a 16-year-old in Queens the day before, police sources say.

According to the sources, the girl was not the intended target in a shooting they believe is tied to another during the weekend that killed a 14-year-old boy.

Law enforcement sources tell News 4 detectives are talking to a person who turned himself in and claims to have shot the 16-year-old girl in the shoulder just before 4 p.m. Monday outside the New Dawn Charter High School in Jaimaica. They say his story must be vetted before moving on with the investigation.

The girl was leaving school when the stray bullet struck her in the arm. She is expected to be OK.

Overnight, police released surveillance video of three individuals they wanted to talk to in connection to the shooting. One of those three is believed to have  turned themselves in.

On Monday sources told News 4 that they believe the shooting that left the girl injured could be connected to another shooting that took place over the weekend that claimed the life of 14-year-old Amir Griffin, who was playing basketball when a stray bullet hit him in the neck around 8 p.m. Saturday.

Griffin's death sparked outrage in the community. 

Both shootings are just two miles apart. Police sources say they could be gang related.
