The suspected gunman, 40-year-old Kimbrady Carriker, is in police custody, the Philadelphia Inquirer reported Tuesday morning.
"Our officers were able to apprehend the male in the rear alley of 1600 Frazier Street and when they did, this male was wearing a bulletproof vest with multiple magazines. He also had a (police) scanner, an AR-style rifle and a handgun underneath his body," Philadelphia Police Commissioner Danielle Outlaw said in a press conference following the mass shooting in Kingsessing.
