Protesters angry over the death of an unarmed teen who was shot by police this week marched Friday for the third straight night down the streets of downtown Pittsburgh.
Four people were arrested as hundreds of demonstrators blocked streets, Allegheny County Police Superintendent Coleman McDonough said.
Police are looking for a black sedan that drove through the crowd late Friday, said Chris Togneri, the city spokesman. No injuries were reported, he said.
Protesters were near PNC Park, where fans were leaving a Pittsburgh Pirates baseball game, when the car drove through, CNN affiliate KDKA reported.
’How do you justify that?’
Antwon Rose, 17, was shot by an officer three times on Tuesday as he attempted to flee a car stopped by police. Rose was one of two passengers in the car, which matched the description of a vehicle that had been involved in an earlier shooting, Allegheny County Police said.
East Pittsburgh Police Officer Michael Rosfeld fired on Rose from behind, hitting him in three spots, police said.
The manner of Rose’s death was listed as homicide, the Allegheny County Medical Examiner’s Office said.
“Three shots in the back, how you justify that?” protesters chanted Friday.
Demonstrators carrying a sign that read, “Fire killer cops,” led hundreds of supporters to the Homestead Grays Bridge, halting traffic for a few hours.
Those arrested face charges for failure to disperse and, at least one, for resisting arrest, McDonough told KDKA.
’He wasn’t that boy’
Tia Taylor, who went to high school with Rose, addressed the crowd, offering a heartfelt testimony of him.
“He wasn’t the person to be out here doing anything he didn’t have no business doing. He wasn’t that boy,” Taylor, a student at Woodland Hills High School, said through tears.
Friday marked the third night of protests in Pittsburgh. Several groups since Wednesday have shut down highways and intersections across the city.
As it grew dark, police became more visible. Squad cars trailed the crowd, and officers in riot gear formed a tight line, holding batons and blocking protesters’ way.
Rosfeld, the officer who shot Rose, had been sworn in to the East Pittsburgh police force just hours before the shooting, though he’d worked with other local departments for seven years, CNN affiliate WPXI reported. He has been placed on administrative leave, police have said.
Allegheny County District Attorney Stephen Zappala does not plan to refer the case to the Pennsylvania attorney general, despite calls for him to do so. Zappala’s spokesman, Mike Manko, said in an emailed statement that “the major crimes investigative resources in Allegheny County are more than capable of handling any homicide case.”
