Matthew Livelsberger, the Green Beret who died in the Las Vegas Cybertruck explosion, left behind a note describing the incident as a “stunt” to serve as a “wake up call” for the country.
Authorities are still combing through the veteran’s electronic devices as they piece together a motive behind the blast outside of the Trump International Hotel on New Year’s Day that left Livelsberger dead and injured seven others. Police have labeled the incident a suicide.
