Police are investigating a Sunday shooting inside a park in Brooklyn that left two teens dead and another wounded.

The NYPD says shots were fired around 6:30 p.m. inside George Walker Junior Park in Cypress Hills. 

Police 16-year-old Kleimer Mendez was shot in the head and died at the scene.

18-year-old Antonio Villa was also shot in the head, police say. He was transported to NYC Health and Hospitals/Kings County, where he later died.

A 17-year-old boy was shot in the leg. 

"I've been in the park all at like different hours and I mean it feels pretty safe. So I mean this, it's alarming," said one man who lives nearby and frequently plays basketball in the park.

NYPD Chief of Detectives Rodney Harrison on Monday evening tweeted surveillance video of the man who he says is the shooter. Harrison says the shooter fired while hanging out of the sunroof of the car he is in. (A man is seen hanging out of the sunroof of a car in the video.)
