Online records suggest John Shick, 30, once lived near the Carleton College campus in Northfield, and college officials confirmed to the Associated Press that Shick was a chemistry major there. He graduated from the college in 2004.
Shick moved to Pittsburgh in August. No witnesses from the incident have reported that Shick said or did anything to explain his motives, and police said they found nothing on him to indicate a reason.
Shick shot seven people, including clinic geriatric therapist Michael Schaab, who was pronounced dead at the scene shortly after the shooting began, the medical examiner’s office said. The surviving victims are expected to recover.
