The driver of the Tesla Cybertruck that exploded outside the Trump International Hotel in Las Vegas on Wednesday has been identified as Matthew Alan Livelsberger, an active-duty US Army Green Beret, according to a law enforcement source familiar with the investigation.

The 42-year-old Texas man showed no signs of radicalization. “It’s a complete surprise, a shock, to everyone,” his half-brother said in an interview.

Fox News initially reported the New Orleans attacker's truck passed across the border into Texas two days before but later issued a correction.

A man "hellbent" on creating carnage drove around barricades and hurtled down Bourbon Street in New Orleans' French Quarter, police said.
