(RNN) – The gunman who killed a psychiatric clinic employee and injured 7 others before being shot dead himself by police has been identified.
John Schick, 30, opened fire in a spray of bullets Thursday at University of Pittsburgh Medical Center's Western Psychiatric Institute.
At least one officer returned gunfire, killing Schick in an attempt to end the shooting spree, according to the Associated Press.
Meanwhile, the hospital is mourning the loss of therapist Michael Schaab, who worked at the institute since 2008.
"It was clear that Michael was truly a leader among our staff, and he was beloved by the geriatric patients whom he care for everyday," Claudia Roth, president of WPIC, said in a statement.
"This senseless act of violence has had a profound impact on all of us who knew and admired him. He will be greatly missed."
Five patients were still receiving care at the University of Pittsburgh Medical Center Friday afternoon. Two patients were listed in serious condition, two in fair condition and one listed in good condition.
On Thursday, Dr. Don Yealy, chief of emergency medicine at UPMC, said he expects all the victims to survive "and do well."
"This is a tragic day, a senseless day. Our empathy goes out to the victims and those involved," Ravenstahl said Thursday afternoon.
Among the injured is a Pittsburgh police officer who was grazed with a bullet, but wasn't seriously wounded.
"[Officers] quick response saved lives today, there's no doubt about it," Ravenstahl said. "We can't predict what would have happened if they hadn't acted so quickly, but there's no doubt their quick response saved lives."
Police believe Schick acted alone, rebutting earlier reports of a second gunman
The clinic is described as a top academic-based psychiatric care center on its website. The school's psychiatry department is part of the clinic.
