Police are still investigating a shooting that occurred Wednesday night outside Washington High School that left a 19-year in the hospital [map].

The 19-year-old victim was standing outside the school when he was shot in the back just before 9 p.m. Wednesday. He then ran into the lobby of the school, where a fashion show was taking place with more than 300 people.

The victim was rushed to Aria Health-Torresdale, and is expected to make a full recovery. Though authorities don’t believe the shooting was connected to the school event, it’s not known yet if the uncooperative victim is a student at Washington, or if he knows the shooter.
