Two people were killed in a triple shooting overnight in North Philadelphia, including a 17-year-old who became the second teenager killed by gunfire in Philadelphia this week.

When officers arrived at the scene near 13th and Rush Streets shortly after 11 p.m. Wednesday, they found two men, ages 24 and 17, gunned down in the street, police said.

The older victim, identified Thursday as Dominique Gainey, of the city's Kensington section, suffered several gunshot wounds to his left side and right leg. He was taken to Temple University Hospital, where he was pronounced dead at 11:37 p.m.

The teen, identified as Irell Williams, of Nicetown, died at Temple at 2:02 a.m. He had been shot in his shoulder and back, police said.

A third victim, a 20-year-old man who was shot in his arm, was taken in a private vehicle to Temple University Hospital. He was listed in stable condition Thursday.

Officers found multiple shell casings just feet from the victims' bodies, indicating they were shot at close range, Chief Inspector Scott Small told reporters.

Investigators don't know the motive for the shooting or which of the three victims, if any, was the intended targeted.

No arrests have been made. Two suspects were seen fleeing from the scene on bicycles. Further descriptions of the assailants were not available.

The shooting marked the second time this week that a teenager was shot to death. On Monday night, a Kensington shooting left a 14-year-old boy dead and a 16-year-old wounded.
