A 23-year-old man identified by law enforcement as Dawson Maloney is dead after he allegedly rammed a power substation outside of Las Vegas around 10 a.m. on Thursday and then committed suicide.
Law enforcement recovered two shotguns, a pistol, ammunition, flamethrowers containing thermite, and a cell phone from the vehicle, according to a press conference.
Police shared video of the man driving a silver Nissan Sentra through a power station gate until he rammed into large industrial wire reels, Las Vegas Metro Police Sheriff Kevin McMahill said in a press conference.
“Given the location and the material discovered, this incident was treated as a terrorism-related event," McMahill said.
Law enforcement said that they recovered books that contained extremist ideologies, including left and right-wing extremist ideologies, environmental extremism, white supremacy, and anti-government ideology.
The New York man apparently rented a vehicle and drove cross-country to Boulder City, Nevada.

Maloney apparently referred to himself as a dead terrorist son.
