Officials said a black vehicle was seen fleeing the area that may have been involved in the shooting.

The vehicle was stopped three blocks from the scene in Ann Alley.

Officials said the 20-year-old driver fled the vehicle and ran through yards before running at a police officer, who fired his weapon.

The man was grazed by the officer’s bullet behind one of the homes on Rosamond Street.

The 21-year-old is now in custody, and the lockdown has been lifted.

“The driver of that vehicle refused to cooperate with the officer, would not follow his instructions,” Allegheny County Police Inspector Andrew Schurman said. “He exited the vehicle and fled on foot. As he was fleeing, the other officers who were backing him up saw him running through the backyards of the neighborhoods. He ran at one of the officers, who discharged his weapon in the direction of the young man, struck him, it was a grazing wound. He was treated and released.”

The suspect has been identified as Kason Murphy, who got into a fight with a bounty hunter in November at a convenience store in Kennedy Township.

Another vehicle, a black Chevrolet Spark with a Missouri plate VD9L6S, was also involved.

It will have heavy bullet damage to the front windshield and possibly be missing the driver’s side window.

Officials said to call 911 if you see the vehicle.
