A second letter appeared to shed more light on Livelsberger’s thinking.
“We are the United States of America, the best country … to ever exist, but right now, we are terminally ill and headed towards collapse,” the letter said. “This was not a terrorist attack. It was a wake up call. Americans only pay attention to spectacles and violence. What better way to get my point across than a stunt with fireworks and explosives. … I need to cleanse my mind of the brothers I’ve lost, and relieve myself of the burden of the lives I took.”
Livelsberger expressed other grievances, including about conflicts elsewhere, domestic issues, societal issues and personal challenges, Koren said. He noted investigators continue to go through evidence found on the cellphone, and Las Vegas Sheriff Kevin McMahill said investigators have been unable to access a second phone found in the Cybertruck.
Spencer Evans, special agent in charge of the Las Vegas FBI, said Friday at the media briefing authorities have not established any firm connections between the Cybertruck explosion and the alleged terrorist attack that occurred in New Orleans only hours earlier that killed 14 people on Bourbon Street.
The only links investigators have established appeared incidental and coincidental, Evan said, adding that the suspects in both cases rented their vehicles from the same company.
Evans added that the investigation determained along with consultation with the Army that Livelsberger likely suffered from PTSD, and that investigators are aware that there were potential “family issues or personal grievances in his own life that may have been contributing factors.”
Livelsberger on Thursday was definitively identified as the suspect behind the blast, Las Vegas police said. The Clark County Coroner determined that he died from a self-infliced gunshot wound, police said.
Authorities said they were able to identify Livelsberger’s badly burned body through various methods, including family DNA and tattoos.
