17-year-old Antwon Rose was killed by a rookie officer who responded to a shots fired call in North Braddock.
Police observed a car speeding from the scene with what appeared to be bullet holes in the rear window.
A traffic stop was made and police detained the driver. Two passengers, including Rose, jumped from the car and fled.
The cop opened fire and Rose was struck multiple times in the back. A witness recorded the shooting with her cell phone.
Police recovered 2 firearms from the car, but Rose was unarmed.
The unidentified cop has been placed on paid administrative leave pending an investigation.
Protestors marched in an impromptu rally outside the East Pittsburgh Police station on Wednesday. Demonstrators called for the officer to be fired.
Rose is the latest in a string of students from Woodland Hills to be shot.
School officials and teachers spoke highly of the teen.
