Philadelphia Mayor Cherelle Parker said Sunday (via CBS NEWS) that the number of injured victims increased from 20 to 22 individuals — five remain hospitalized, three of whom are in critical condition.

The National Transportation Safety Board said the medical jet departed from a base in Florida around noon and arrived in Northeast Philadelphia around 2:15 p.m., headed to Springfield, Mo.,with the final destination in Tijuana, Mexico. NTSB Chair Jennifer Homendy told reporters there was no indication of a problem radioed to air traffic control before the crash, which left debris scattered across four to five city blocks near Roosevelt Mall. The NTSB said investigators are still looking for the plane’s cockpit voice recorder.
