The injured SEPTA officer is 28 years old. He has been on the force for three years.
Philadelphia Police Commissioner Danielle Outlaw released this statement on the incident:
"The decision to utilize deadly force is the most serious action a police officer can undertake. During this incident, four innocent people were shot. The fact that this occurred in the area of a busy transportation hub and neighborhood makes it even more harrowing. I hope for the full recovery of these four victims, and remain grateful that there were not additional injuries to civilians and responding officers. As with all officer involved shootings, we will ensure that a thorough, complete and objective investigation takes place."
