The Pennsylvania officer who opened fire and killed a 17-year-old as he was running away from a traffic stop had been sworn in to his job only hours earlier, according to a report.
Antwon Rose was killed Tuesday night in East Pittsburgh, where he and another boy fled a car they were passengers in as the driver was detained.
Facebook video shows him leaving the car as shots ring out and he falls.
Detectives from Allegheny County are investigating the shooting, which the officer has not yet explained why he fired at the fleeing teen.
Sources told KDKA that the unidentified officer involved had only been working for the department for three weeks, and was sworn into duty only around 90 minutes before the shooting.
East Pittsburgh’s mayor had said that the officer had previously worked several years for another police department.
The car had been stopped after it matched the description of the vehicle seen in another nearby shooting where a 22-year-old was injured.
Police found two guns in the car, but none on Rose as he was shot and the attorney for his family, Lee Merritt, said he was not armed and that there was no substantiated connection to the other shooting.
The driver of the car was released after being questioned by police.
Pennsylvania law allows officers to shoot at those fleeing only if they have a gun or there is an immediate danger of them causing death or serious injury.
Investigators said that Rose was hit three times.
The death of the high school senior, expected to soon graduate, sparked protests in the city east of Pittsburgh.
“From all accounts, he was a generous, hard-working and highly promising student. Affirmations of his generosity of spirit and genuine good heartedness have begun pouring in from all corners of the East Pittsburgh community where he lives,” Merritt said in a statement.
