Police presence was heavy on in the 7900 block of Rugby Street.
14th District Officers responded to a call of a fight between a man and his girlfriend.
The officers were able to calm the couple down and settle the domestic dispute, but moments later, the woman's brother, 39 year old Eric Crawley, showed up with a holstered gun.
"They tell the male not to remove the gun, he removes the gun. The officer fired one shot," explained Lt. Ray Evers.
Internal affairs spent the day on the scene investigating.
Police have not been able to release many details about the officer involved shooting or Crawley who was killed in the middle of the street.
Action News has learned that Crawley was a bus driver for SEPTA.
The officer's name has not been released. Officials say the officer only fired one shot, and no one else was injured.
"There was child involved. We are not sure whether that was the result of the dispute, but there was a child in the household," explained Lt. Evers.
Investigators also spent time searching a nearby school bus, but spokesman for the department would not comment on the search.
Earlier Friday, police shot and wounded a man following a brief chase. Investigators say that man was in a car that dropped off a gunshot victim at Frankford Hospital and sped away.
That man was wounded in the arm.
