Among the dead was Lewis Katz, co-owner of The Philadelphia Inquirer, the Philadelphia Daily News and philly.com. He was 72.

He once owned the NBA's New Jersey Nets and the NHL's New Jersey Devils and is a major donor to Temple University, his alma mater,"philly.com reported. The crash came just a few days after Katz and H.F. "Gerry" Lenfest won control of the parent company that owns those news agencies with an $88 million bid at an auction, the Philadelphia Business Journal reported. "Words cannot express our sadness at this time regarding the sudden loss of Lewis Katz," the parent company, Interstate General Media, said in a statement. It expressed condolences to Katz's family and friends, "and to so many that his life and generosity touched through his countless acts of kindness." The names of the other victims have not been released. The plane apparently caught fire, according to the Federal Aviation Administration. Purported photos of the crash on social media showed flames and smoke. Fire department rescuers responded to the scene of the crash early Sunday.
