Christopher Battle, 24, faces multiple murder charges stemming from a mass shooting in the Grays Ferry neighborhood last summer.
The gunfire broke out just before 1 a.m. July 7 on South Etting Street.
Three people were killed: 23-year-old Zahir Wylie, 19-year-old Jason Reese and 24-year-old Azir Harris. Nine others were wounded in the shooting.

Investigators said at least 13 different firearms were discharged during the incident. Battle is now the fifth person charged in connection with the mass shooting.
Officials said that there was no argument or opposing party at the gathering when the shots rang out. They believe there was one individual among the group who fired a gun, possibly into the air, which caused at least a dozen other people with firearms to begin "recklessly and, really, intentionally," firing their guns.
