A shooter opened fire in the psychiatric unit of Mercy Fitzgerald Hospital in Darby, Pennsylvania on Thursday, killing one female employee and injuring a doctor, authorities said.
The suspected shooter was also shot and is in critical condition, Delaware County District Attorney Jack Whelan said in a press conference Thursday afternoon. Whelan said the suspects’ injuries were not believed to be self-inflicted, but it’s still unclear who shot him.
Whelan added that the shooter had “psychiatric issues,” though police are still investigating the motive for the attack.
Mercy-Fitzgerald Hospital, a teaching hospital, is part of a regional Catholic healthcare network, Mercy Health System. It’s located several miles south of downtown Philadelphia.
