A man wanted in a triple shooting this year has turned himself in, Philadelphia police said Tuesday.

Joshua Raheem, 21, of West Philadelphia, has been charged with murder and other offenses in the June 6 shooting death of John Carrington, 21, of Parkside, and the wounding of a 15-year-old boy and a 22-year-old man.

Homicide detectives conducted an "intensive investigation," police said, and issued a warrant for Raheem, who surrendered to police Monday.
