What we know about the police shooting death of Antwon Rose Jr.

Community members in East Pittsburgh, Pennsylvania, continue to protest the police shooting this week of an unarmed black teen whose fatal encounter with an officer Tuesday was captured on video by a bystander’s cell phone.

A Pittsburgh-area police officer shot 17-year-old Antwon Rose Jr. three timesTuesday as he fled the scene of a traffic stop, authorities said.

The black teen was the passenger of a car suspected by police to be involved with a shooting earlier that day, the Allegheny County Police Department said in a statement, adding that Rose was unarmed when an officer fatally shot him.

Here’s what we know about what happened and what police and the community will do next.

What police say

Allegheny County police received multiple 911 calls of a shooting around 8:20 p.m. ET Tuesday, the department said in its initial statement on Facebook. Responding officers found a wounded 22-year-old male who was subsequently transported to a nearby hospital for treatment.

Witnesses who reported the incident provided a description of a car that was seen fleeing the scene of the shooting: a silver Chevrolet Cruze that also had “ballistics damage to the rear window.” About 13 minutes later, an East Pittsburgh officer flagged a vehicle that matched the description of the car and stopped it.

The officer handcuffed the driver, while two passengers who were also in the vehicle ran away, police said. That’s when an officer shot and killed the teen who was later identified as Rose. He was declared dead at a local hospital. On Friday, Allegheny County District Attorney Stephen Zappala confirmed that police found an empty gun clip on Rose.

The driver, 20, was released by authorities after he was questioned. The third suspect has yet to be located by authorities.

In a news conference the following day, Allegheny County Police Superintendent Coleman McDonough confirmed that Rose was unarmed when he “bolted” from the scene. Two firearms were recovered from the floor of the car, McDonough said.

“I’m very confident that that was the vehicle involved in the shooting,” McDonough told reporters.

The superintendent also said the officers involved were not wearing body cameras, nor was the vehicle equipped with any cameras. The officer who fatally shot Rose — identified as Michael Rosfeld — has been placed on administrative leave while the shooting is being investigated, McDonough said. He would not answer other questions about the officer, including on Rosfeld’s race.

East Pittsburgh Mayor Louis Payne said Rosfeld, who has eight years of police experience at other departments, was formally sworn in hours before the shooting, the Pittsburgh Post-Gazette reported.

When asked about the “groundswell” of outrage from the community over the police shooting, McDonough said, “I understand in today’s atmosphere anytime a young man is killed there’s cause for outrage in some areas … however, I would urge people to give us time to conduct an objective investigation, to gather facts.”

What can you see in the bystander video?

A bystander filmed the deadly encounter on video and posted it to Facebook.

In the 17-second video, a second police vehicle arrives at the scene as two people are seen running away from the parked police vehicle in the middle of the street. Then, three gunshots ring out.

“Why are they shooting at him?” the person recording the shooting is heard saying. “All they did was run, and they’re shooting at them.”

Upon seeing the video of the shooting, Antwon’s aunt Mica Tinsley is quoted by the Post-Gazette as saying, “They’re not even saying stop … They just started shooting, and he fell. He didn’t make it far.”

“Any loss of life is tragic, and especially the loss of life of a child. This is a devastating situation and I am saddened for Antwon Rose and his family,” Pittsburgh Mayor William Peduto said in a statement.

What’s next?

The shooting death of Rose comes amid continuing national scrutiny of police use of force, particularly against black Americans. Protests have swelled this week with hundreds of peaceful protesters marching on a major interstate Thursday, shouting “No justice! No peace!” and carrying “Justice4Antwon” signs.

Pennsylvania state and Allegheny County police, among other law enforcement agencies, are investigating the shooting. The district attorney has yet to decide on whether criminal charges would be brought against the officer.
