Stephen Paddock opened fire on a country music concert from his hotel room in Las Vegas, killing over 50 people and injuring hundreds more. Click through the gallery to find out more about the coldblooded Nevada killer who has carried out the worst mass shooting in United States history to date.
Paddock is a 64-year-old man who lived in a retirement community in Mesquite, Nevada, one hour north of Vegas.
Paddock lived in a newer but unremarkable home on a cul de sac in the 55-plus community.
He has been linked to a companion, a 62-year-old woman named Marilou Danley, who police now confirm was not involved in the shooting and is not a suspect.
Danley, who is currently out of the country, lived with Paddock in Mesquite.
According to NBC News, Paddock was in the middle of a divorce when he carried out the deadly attack on concertgoers.
According to Paddock's brother, Eric, the killer liked to go into Las Vegas so he could gamble.
Paddock's brother claimed his identity was determined after police stormed his room and went through his wallet, which was found on his body.
Paddock had no problems with police in Mesquite, noted officials. However, he sued the Cosmopolitan hotel in 2012 after he claimed he was injured after slipping. The suit was dropped two years later. He was also issued a minor citation several years ago.
"He was just a guy. Something happened, he snapped or something," said Paddock's brother Eric, who lives in Orlando, Fla. "We know absolutely nothing, this is just, we are dumbfounded."
Paddock was not known to be an avid gunman, said his brother, and "he has no military background."
