An ex-girlfriend of the Las Vegas explosion suspect recently shared text messages with the FBI that shed light on his behavior leading up to the tragic event. The suspect, Matthew Livelsberger, had reached out to Alicia Arritt just days before the New Year's Day explosion outside President-elect Trump's Las Vegas hotel. Arritt and Livelsberger had dated from 2018 to 2021, but had since moved on from their relationship.
Arritt described Livelsberger as a kind and generous man who had supported her during a difficult time, even buying her a house when her mother fell ill. However, she was unaware of Livelsberger's alleged plans to take his own life inside a rented Tesla Cybertruck loaded with explosives.
