Four teens are recovering from gunshot wounds they suffered when someone opened fire during a Saturday-night vigil in Southwest Philadelphia for a boy who was killed in an accident with a private trash truck Friday.

Police said the injured teens - three boys and a girl - were treated at Children's Hospital. Two were released Saturday night, and two on Sunday.

Police spokesman Sgt. Ray Evers said the 15-year-old girl was wounded in the buttocks; a 14-year-old youth was shot in the right leg; a 15-year-old youth also was shot in the right leg; and another 15-year-old youth was shot in the right hand.

Investigators say they believe the gunfire that erupted about 9 p.m. at 58th Street and Elmwood Avenue was in retaliation for an incident that occurred in the neighborhood earlier in the week. Police do not believe the teens who were shot were the intended targets.

Evers said police have recovered a .40-caliber handgun and have identified several people of interest but have made no arrests. - Martha Woodall
