The enigma surrounding the Tesla Cybertruck explosion outside the Trump International Hotel in Las Vegas on New Year’s Day has only intensified, as the latest report from local authorities sheds little new light on the motive behind the incident.

The Las Vegas Metropolitan Police Department (LVMPD) released a comprehensive 78-page “after-action” report on Monday, confirming that Matthew Livelsberger, who took his own life before the explosion, had left behind a manifesto. This document was discovered on his phone during a forensic investigation.

According to the report, the Department of War has classified the manifesto, leading to the federal government taking over the investigation.

As detailed in the report, which was obtained by Fox News Digital, it was verified that the Green Beret was on leave from his Special Forces unit at the time and had rented the Tesla Cybertruck via the car-sharing service Turo.

He filled it with fireworks, gas cans and camping fuel, and drove it to the Trump International Hotel just after 8:40 a.m. on Jan. 1, 2025. There, the vehicle detonated, causing damage and injuring six people.

LVMPD and federal investigators described the incident as a premeditated vehicle-borne improvised explosive device (VBIED) attack “with the potential to cause mass casualties and extensive structural damage” but did not call it terrorism.

Investigators also reconstructed Livelsberger’s final days using phone data, bank records and surveillance footage.

Surveillance video showed Livelsberger pouring accelerant into the truck bed moments before detonation, an act LVMPD said reflected planning rather than impulse.

Counterterrorism investigators concluded he sought to make “a very big, very public statement,” suggesting the Las Vegas location was chosen for visibility and impact.

He also left behind a note claiming the attack was not terror-related, but a way for the soldier to “cleanse” his mind but criticized the “feckless leadership” of a U.S. that is “near collapse,” officials said.

“This was not a terrorist attack, it was a wake-up call,” Livelsberger wrote in the notes app on his phone.

“Americans only pay attention to spectacles and violence. What better way to get my point across than a stunt with fireworks and explosives,” Livelsberger wrote.

One of his messages was said to have gone to Shawn Ryan, an ex-Navy SEAL and CIA contractor.
