… Law enforcement sources told CBS News that the Cybertruck was rented to Matthew Alan Livelsberger, an active duty U.S. Army servicemember who was serving in Germany but was on leave in Colorado at the time of the incident. CBS News spoke to two relatives of Livelsberger who were unaware of any involvement in the incident, but who confirmed he had rented a Cybertruck. One relative told CBS News that Livelsberger’s wife had not heard from him in several days.

McMahill said gasoline canisters, camp fuel canisters and large firework mortars were found in the back of the vehicle after the explosion, which occurred about 15 seconds after the vehicle pulled in front of the building. It’s still unclear how the explosives were ignited, he said.
