An unauthorized street party at a city recreation center near 33rd and Diamond streets, in Strawberry Mansion, erupted in gunfire last night, and a young man in his 20s was killed, police said.
Three others - including a 6-year-old girl, a 10-year-old girl and a 15-year-old girl - were also wounded in the melee. Authorities said that all were in critical but stable condition at Temple University Hospital.
As recounted by police, about 200 people gathered in front of the recreation center for the illegal party, and alcohol was served.
At some point, a group of boys attacked another boy, who then went home, got a gun and came back and fired into the crowd, police said.
