The gunman opened fire on the officers, and all four fired back, the commissioner said. Two officers were struck – one suffered an elbow wound that will require surgery while the other was grazed on the nose.
It was unclear what sparked the shooting and investigators were looking into the histories of both men, Outlaw said. Police believe the shooting was targeted.
The shooter was described as a man in blue scrubs and a mask with a black backpack. The clothes and U-Haul truck he allegedly fled the scene in was later recovered by officers.
Investigators have not released any further details on the suspect or victim and it remains unclear what led to the gunfire.
The suspect opened fire on the ninth floor of the Thomas Jefferson University Hospital in Center City, according to 6 ABC
