CNN) — The pilot of a small plane that slammed into a building Thursday morning in Austin, Texas, set his house on fire beforehand and then intentionally crashed the aircraft, a federal official told CNN.
Federal officials told CNN the plane was a Piper Cherokee PA-28 they believe belonged to Joseph Andrew Stack.
Two F-16 fighter jets were sent from Houston as a precaution, but federal authorities said preliminary information did not indicate any terrorist connection to the crash.
“We do not yet know the cause of the plane crash,” the Department of Homeland Security said in a release. “At this time, we have no reason to believe there is a nexus to terrorist activity. We continue to gather more information, and are aware there is additional information about the pilot’s history.
“At this time, we are referring further questions to local authorities and the FAA.”
Two people were transported to University Medical Center Brackenridge, said hospital spokeswoman Matilda Sanchez. She could not provide additional information.
