There are new details tonight about the man believed responsible for exploding a Tesla

cyber truck last week in front of the Trump Hotel in Las Vegas. Police and military officials

now believe Matt Livelysberger suffered post-traumatic stress disorder, and we now have some

of the final words that he wrote that might help explain the end of the life of a decorated special forces soldier.

Here's Nick Schifrin.

Matthew Livalzberger was a warrior, a career special forces soldier known as a Green Beret.

In 13 years, he deployed nine times, including five times to Afghanistan,

and rose to become an intelligence, then team sergeant with the rank

of a master sergeant. But his final days were spent on leave, stopping at Tesla charging stations

on a circuitous route from Colorado to Las Vegas, where he died by suicide before exploding his

rented Tesla cyber truck in front of Trump Tower. In notes on his phone released by Las Vegas police, he called out, quote, military and vets,

be prepared to fight to get the Dems out of the Fed government.

But he also wrote, why did I personally do it now?

I needed to cleanse my mind of the brothers I've lost and relieve myself of the burden of the lives I took.

U.S. officials confirm Livalzberger, like so many other warriors, suffered trauma from service,

including a reported traumatic brain injury. He also suffered moral injury.

You want to read the email?

Yep.

That he detailed Army intelligence officer Sam Shumate who read a Livelylisberger email

on the Sean Ryan podcast. In the email, Livalzberger admitted he participated in a 2019

strike in Afghanistan that he said killed hundreds of civilians and a subsequent cover-up.

Livalzberger was also in touch with an ex after splitting up from his second wife.
