PITTSBURGH — City and University of Pittsburgh police are trying to determine whether a student fell or jumped from a seventh-floor dormitory window.

Authorities aren’t identifying the student, though friends have said he is an 18-year-old freshman.

City police spokeswoman Sonya Toler said the student “fell or jumped” from the window.

The university said in a statement that the student was found injured by campus police early Saturday.

Among other things, police are trying to determine if drugs or alcohol contributed to the incident.

The student was being treated at UPMC Presbyterian hospital.
