A West Philadelphia man faces murder charges after police say they spent months tracking him down.

Joshua Raheem, 21, turned himself in Monday after detectives from the Homicide Unit issued a warrant at his home on Baltimore Avenue near 54th.

Raheem is a key suspect in a triple shooting June 6 that claimed the life of John Carrington, 21, and critically injured two other males.

In that incident, which took place on Thompson Street near 50th in the Parkside section of West Philadelphia, Carrington was shot multiple times and was pronounced dead shortly after being transported to the Hospital of the University of Pennsylvania. Another victim, 15, was shot once in the back, and a third, 22, was shot in both legs.

Raheem has been charged with murder, gun violations and related offenses in the incident, according to police.
