The suspect was identified using fingerprints and an ID, according to the FBI, which is now asking the public for help in finding out more information about him. Alexis was apparently shot by police responding to the incident, the FBI said.
It is unclear whether another gunman was involved. At least 13 people, including Alexis, were killed, officials announced. Several others have been injured and are being treated at area hospitals.
