The FBI has concluded its investigation into the Oct. 1, 2017, massacre of country music festival attendees in Las Vegas without determining a motive for the killer.
Using a room on the 32nd floor of the nearby Mandalay Bay Hotel as a vantage point, the killer shot and killed 58 people and wounded more than 500 others. He died from a self-inflicted gunshot wound.
Here's what we know
The FBI said that it could not determine any grievances that the killer, Stephen Paddock, had that would have led to this tragedy.
Paddock, who was 64 years old at the time, was a retired postal worker and a high-stakes gambler. He was reportedly a loner and had no known religious or political affiliation.
The report was compiled by the Las Vegas Review Panel, a "diverse group of experts from within and outside the FBI."
The report concluded that:
The LVRP found no evidence that Paddock's attack was motivated by any ideological or political beliefs. The LVRP concludes that Paddock's attack was neither directed, inspired, nor enabled by ideologically-motivated persons or groups. Paddock was not seeking to further any religious, social, or political agenda through his actions. The LVRP further assesses that Paddock conspired with no one; he acted alone.
It also said that "there was no single or clear motivating factor behind Paddock's attack" and that they had not found "a manifesto, video, suicide note, other communication ... related to the planned attack or explaining his reason for attacking."
Nor did they find a reason that he attacked that specific venue, besides it being a "tactically-advantageous location" for an attack that was meant to kill as many people as possible.
The only clear thing the report stated about Paddock was that it was his "intention to die by suicide." It also concluded that Paddock was likely "influenced by the memory of his father," a bank robber who spent time on the FBI's Most Wanted list.
Didn't we already see a report on this massacre?
The local police had concluded its own investigation in August. The police also could not determine a motive for Paddock, but came to the conclusion that he had worked alone. Although it was not listed as a possible motive, he had also lost more than $1 million from gambling during the previous year.
