The suspected gunmen in the Las Vegas shooting has been identified as 64-year-old Stephen Paddock of Mesquite, Nevada.
Las Vegas Metropolitan Police Department Sheriff Joseph Lombardo said that the shooter was found dead in a room on the 32nd floor of Mandalay Bay in an apparent suicide. Lombardo said Paddock opened fire from the room, and there were no other shooters. Police said he had no known connection to terrorism.
"We have no idea what his belief system was," Lombardo said.
At least 58 people were killed and more than 500 were sent to hospitals after the gunman opened fire on more than 22,000 concertgoers in Las Vegas late Sunday. It was the deadliest mass shooting in modern U.S. history.
Lombardo said the police department had located a number of firearms in the room he occupied in the hotel. Officers also carried out a search on Paddock's residence in Mesquite, 90 miles northeast of the hotel.
Paddock was not known to the federal authorities, but was known to local law enforcement, according to NBC News. Police confirmed Paddock was the son of bank robber Patrick Benjamin Paddock, who was on the FBI's Top 10 most wanted list for over a decade until 1977. The original FBI posting described the elder Paddock as "psychopathic ... with suicidal tendencies."
Several police officials and a casino executive told NBC News that Paddock had gambled more than $10,000 per day multiple times over the past several weeks. The reports do not reveal if, or how much, Paddock won or lost on those days.
