A 21-year-old woman was getting ready to go to bed in her Southwest Philadelphia home last night when a bullet crashed through her window and struck her in the head, critically wounding her, police said.

The woman was about a block away from Daggett Street and Dicks Avenue in Elmwood, where police found two men suffering from gunshot wounds on the street about 9:20 p.m., said Lt. John Walker of Southwest Detectives. A few minutes later, cops were called to Buist Avenue near 65th Street, where they found the injured woman in a bedroom, Walker said.

All three were taken to the Hospital of the University of Pennsylvania. The woman was in critical condition about 10:30 p.m. One man, shot in the head, was also critical, and the second man, shot in the shoulder, was stable.

A few blocks away, at 61st Street and Elmwood Avenue, police found a fourth shooting victim they believe was also wounded on Daggett Street. That man, in his early 20s, was shot in the side and taken to HUP in critical condition, Walker said. Police said they also found a gun lying under the man.

At least 27 shots were fired at the scene, Walker said.

Police don't yet know of a motive but believe the three men were intended targets.

"We're trying to get some cooperation from the public. We need people to come forward," Walker said.

Anyone with information about the shooting is asked to call Southwest Detectives at 215-686-3183.
