The East Pittsburgh police officer who shot and killed unarmed 17-year-old Antwon Rose has been charged with criminal homicide after prosecutors determined that he was never threatened during the incident, NBC News reports.

Michael Rosfeld, 30, turned himself in on Wednesday and was charged with one count of homicide.

Rose was shot three times on June 19 by Rosfeld as he and another teen ran from the car during a traffic stop.

The vehicle he was in matched the description of a car that was linked to a drive-by shooting earlier that night, per reports.

District Attorney Stephen Zappala Jr. told reporters at a news conference that he has enough evidence to pursue a case for third-degree murder, which could land Rosfeld in prison for 20-40 years, adding that prosecutors could argue first-degree murder, which carries a life sentence.

“You can’t take somebody’s life under these circumstances,” Zappala said.

Video of the shooting was posted on Facebook and shows Rose and Zaijuan Hester, 17, seen exiting a light-colored Chevy Cruze from the passenger side and run away before gunshots ring out.

Surveillance cameras show someone sitting the rear passenger window of a light-colored Chevy Cruze shooting a handgun with .40 caliber bullets. The bullet casings found at the scene as confirmed to have come from a .40 caliber Glock that was found under the back portion of the passenger seat, per NBC News.

Rose was sitting in the front passenger seat and did not fire any of the shots, according to a complaint that was filed.

“Antwon Rose didn’t do anything except be in that vehicle,” Zappala said.

Rosfeld was sworn in as an East Pittsburgh Police officer hours before. He was arraigned on Wednesday and his bail was set to $250,000.
