Just finished watching 12:00 noon WPVI (on air) news; the report detailed "unspecified injuries", and "police and airport officials are continuing to investigate" and left it at that. It was a slow news day, today...
Take what you may from this:
Penn-Presbyterian Medical Center is not the closest receiving facility with a trauma center to PHL (Crozer-Chester, a Level II trauma center/burn unit in the City of Chester, Delaware County, is). Presby is a Level I trauma center, and is a hospital which is well known for providing (both) excellent medical care and surgical trauma intervention. Advanced trauma would have been transported to The Hospital of the University of Pennsylvania; neurological trauma/emergencies would have gone to Thomas Jefferson University Hospital (another Level I trauma center). All three Philadelphia facilities are approximately equidistant from the main terminals at PHL.
Sounds as if the news organizations in Philly are not going to be issuing anymore updates;
Philly.Com, the website of Philadelphia Newspapers, Inc., doesn't even refer to the incident.
