Authorities believe Livelsberger died from a self-inflicted gunshot wound before the vehicle detonated. He was identified through tattoos, credit cards, and military identification found at the scene. Livelsberger, on leave from his station in Germany with the 10th Special Forces Group, had multiple addresses associated with him.
