Man who exploded Tesla Cybertruck outside Trump hotel in Las Vegas used generative AI, police say

The highly decorated soldier who exploded a Tesla Cybertruck outside the Trump hotel in Las Vegas used generative AI including ChatGPT to help plan the attack, Las Vegas police said Tuesday.

Nearly a week after 37-year-old Matthew Livelsberger fatally shot himself, officials said according to writings, he didn’t intend to kill anyone else.

An investigation of Livelsberger’s searches through ChatGPT indicate he was looking for information on explosive targets, the speed at which certain rounds of ammunition would travel and whether fireworks were legal in Arizona.

Kevin McMahill, sheriff of the Las Vegas Metropolitan Police Department, called the use of generative AI a “game-changer” and said the department was sharing information with other law enforcement agencies.

“This is the first incident that I’m aware of on U.S. soil where ChatGPT is utilized to help an individual build a particular device,” he said. “It’s a concerning moment.”

In an emailed statement, OpenAI said it was committed to seeing its tools used “responsibly” and that they’re designed to refuse harmful instructions.

“In this case, ChatGPT responded with information already publicly available on the internet and provided warnings against harmful or illegal activities. We’re working with law enforcement to support their investigation,” the emailed statement said.

Launched in 2022, ChatGPT is part of a broader set of technologies developed by the San Francisco-based startup OpenAI. Unlike previous iterations of so-called “large language models,” the ChatGPT tool is available for free to anyone with an internet connection and designed to be more user-friendly.

During a roughly half-hour-long news conference, Las Vegas police and federal law enforcement officials unveiled new details about the New Year’s Day explosion.

Among the specifics law enforcement disclosed: Livelsberger stopped during the drive to Las Vegas to pour racing-grade fuel into the Cybertruck, which then dripped the substance. The vehicle was loaded with 60 pounds (27 kilograms) of pyrotechnic material as well as 70 pounds (32 kilograms) of birdshot but officials are still uncertain exactly what detonated the explosion. They said Tuesday it could have been the flash from the firearm that Livelsberger used to fatally shoot himself.

Authorities also said they uncovered a six-page document that they have not yet released because they’re working with Defense Department officials since some of the material could be classified. They added that they still have to review contents on a laptop, mobile phone and smartwatch.

Among the items released was a journal Livelsberger kept titled “surveillance” or “surveil” log. It showed that he believed he was being tracked by law enforcement, but he had no criminal record and was not on the police department’s of FBI’s “radar,” the sheriff said Tuesday.

The log showed that he considered carrying out his plans in Arizona at the Grand Canyon’s glass skywalk, a tourist attraction on tribal land that towers high above the canyon floor. Assistant Sheriff Dori Koren said police don’t know why he changed his plans. The writings also showed he worried he would be labeled a terrorist and that people would think he intended to kill others besides himself, officials said.

Once stopped outside the hotel, video showed a flash in the vehicle that they said they believed was from the muzzle of the firearm Livelsberger used to shoot himself. Soon after that flash, video showed fire engulfing the truck’s cabin and even escaping the seam of the door, the result of considerable fuel vapor, officials said. An explosion followed.

Livelsberger, an Army Green Beret who deployed twice to Afghanistan and lived in Colorado Springs, Colorado, left notes saying the explosion was a stunt meant to be a “ wake up call ” for the nation’s troubles, officials said last week.

He left cellphone notes saying he needed to “cleanse” his mind “of the brothers I’ve lost and relieve myself of the burden of the lives I took.”

The explosion caused minor injuries to seven people but virtually no damage to the Trump International Hotel. Authorities said that Livelsberger acted alone.

Livelsberger’s letters touched on political grievances, societal problems and domestic and international issues, including the war in Ukraine. He wrote that the U.S. was “terminally ill and headed toward collapse.”

Investigators had been trying to determine if Livelsberger wanted to make a political point, given the Tesla and the hotel bearing the president-elect’s name.

Livelsberger harbored no ill will toward President-elect Donald Trump, law enforcement officials said. In one of the notes he left, he said the country needed to “rally around” him and Tesla CEO Elon Musk.

On New Year’s Eve 2024, journalist Jacob Soboroff was sitting around a campfire with a friend when he made an offhand comment that would come back to haunt him: The last thing he wanted to do in the new year, Soboroff said, was cover a story that would require donning a fire-safe yellow suit.

Just one week later, Soboroff was dressed in the yellow suit, reporting live from a street corner in Los Angeles as fire tore through the Pacific Palisades, the community where he was raised.

“This was a place that I could navigate with my eyes closed,” Soboroff says of the neighborhood. “Every hallmark of my childhood I was watching carbonize in front of me. … There were firefighters there and first responders and other journalists there, but it was an extremely lonely, isolating experience to be standing there as everything I knew burned down around me in real time.”

In his new book, Firestorm: The Great Los Angeles Fires and America’s New Age of Disaster, Soboroff offers a minute-by-minute account of the catastrophe, told through the voices of firefighters, evacuees, scientists and political leaders. He says covering the wildfires was the most important assignment he’s ever undertaken.

“The experience of doing this is something that I don’t wish on anybody, but in a way I wish everybody could experience,” he says. “It’s given me insane reverence for our colleagues in the local news community here, who, I think, definitionally were exercising a public service in the street-level journalism that they were doing and are still doing. … It was actually beautiful to watch because they are as much a first responder on a frontline as anybody else.”

Interview highlights

Firestorm, by Ben Soboroff

On the experience of reporting from the fires

You’re choking with the smoke. And I almost feel guilty describing it from my vantage point because the firefighters would say things to me like: “My eyeballs were burning. We were laying flat on our stomach in the middle of the concrete street because it was so hot, it was the only way that we could open the hoses full bore and try to save anything that we could.” …

I could feel the heat on the back of my neck as we stood in front of these houses that I remember as the houses that cars and people would line up in front of for the annual Fourth of July parade or the road race that we would run through town. Trees were on fire behind us — we were at risk of structures falling at any given minute. It was pretty surreal because this is a place I had spent so much time as a child and going back to as an adult. … I had no choice but to just open my mouth and say what I saw to the millions of people that were watching us around the country.

On undocumented immigrants being central to rebuilding the city

These types of massive both humanitarian and natural disasters give us X-ray vision for a time into sort of the fissures that are underneath the surface in our society. And Los Angeles, in addition to being one of the most unequal cities between the rich and the poor, has more undocumented people than virtually any other city in the United States of America. Governor Newsom knew that with the policies of the incoming administration, some of the very people that would be responsible for the cleanup and the rebuilding of Los Angeles may end up in the crosshairs of national immigration policy. And I think that that was an understatement. …

Pablo Alvarado in the National Day Laborer Organizing Network said to me that often the first people into a disaster — the second responders after the first — are the day laborers. They went to Florida after Hurricane Andrew, to New Orleans after Katrina, and they’d be ready to go in Los Angeles. And I went out and I cleaned up Altadena and Pasadena with some of them in real time.

And only months later did this wide-scale immigration enforcement campaign begin … on the streets of LA as sort of the Petri dish, the guinea pig for expanding this across the country. And it’s not an exaggeration to say that the parking lots of Home Depots, where workers [were] looking to get involved in the rebuilding of Los Angeles, has been ground zero for that enforcement campaign.

The pace is slow and it’s sort of a hopscotch of development. And I think for people who do come back, for people who can afford to come back, it’s going to be a long road ahead. You’re going to have half the houses on your street under construction for years to come. And for people that do inhabit those homes, it’s going to an isolating experience. But there’s an effort underway to rebuild. …

There’s also a lot of for-sale signs. And that’s the sad reality of this, is that there are people who, whether it’s that they can’t afford to come back … or that they just can’t stomach it, I think, sadly, a lot people are not going to be returning to their homes.

On what the Palisades and Altadena look like today

They both look like very big construction sites in a way. There are still some facades, some ruins of the more historic buildings in the Palisades. … But mostly it’s just empty lots. And in Altadena, the same thing. If you drive by the hardware store, the outside is still there. But it’s a patchwork of empty lots. Homes now under construction. And lots and lots of workers. … There are still a handful of people who are living in both the Palisades and in Altadena, but for the most part, these are communities where you’ve got workers going in during the day and coming out at night. …

We have designed this community to be one that’s in the crosshairs of a fire just like the one we experienced and that we will certainly, certainly experience again, because nobody’s packing it up and leaving Los Angeles. People may not return to their communities after they’ve lost their homes, but the ship has sailed on living in the wildland urban interface in the second largest city in the country.

I don’t think I realized at the time how badly I needed the connections that I made in the wake of the fire, both with the people who have lost homes and the firefighters, first responders who were out there, but also honestly with my own family, my immediate family, my wife and my kids, my mom and my dad and my siblings and myself. I think that this was a really hard year in LA, and I think in the wake of the fire, I was experiencing some level of despair as well. Then the ICE raids happened here and sort of turned our city upside down. And this book for me was just this amazing cathartic blessing of an opportunity to find community with people I don’t think I ever would have otherwise spent time with, and to reconnect with people who I hadn’t seen or heard from in forever.
