The gunman responsible for the worst mass shooting in modern US history is believed to be a grandfather who lived in a remote desert home.
Stephen Paddock, 64, was named by police as the perpetrator of last night's mass shooting.
The Nevada native left 58 people dead after opening fire on the Route 91 Harvest Festival from a hotel window on the Las Vegas Strip.
US records show he lived in a three-year-old, $396,000 (€337,000) two-bedroom home in the tiny desert community of Mesquite, 120km northeast of Las Vegas, near the Arizona state border.
Paddock was a former accountant and a licensed pilot with no criminal record, according to ABC News.
He had bought the new home in the quiet retirement community in 2015 in order to be near casinos, according to his brother, Eric Paddock.
From there, it was only an hour's drive to Las Vegas, where he embarked yesterday on the worst mass shooting in recent US history before taking his own life.
His brother, Eric Paddock, said he was a peaceful man who moved back to Nevada, where gambling is legal, partly because of his fondness for video poker.
"He's never drawn his gun, it makes no sense," Mr Paddock said from his doorstep in Orlando, Florida. His brother had a couple of handguns he kept in a safe, perhaps a long rifle, "but no automatic weapons."
Eric Paddock said he had helped his brother move away from Central Florida's humidity to Nevada. The two were last in touch last month, texting about power outages after Hurricane Irma slammed into Florida.
Their father was Patrick Benjamin Paddock, a violent bankrobber who was on the Federal Bureau of Investigation's Most Wanted list in the 1960s, NBC News reported.
The gunman himself had no criminal record apart from a traffic violation, police in Las Vegas said.
A former neighbour named Sharon Judy in Viera, Florida, told the Orlando Sentinel that Stephen Paddock was a friendly man who said he was a professional gambler. He had shown her a picture of him after he won a $20,000 slot-machine jackpot, she said.
In recent weeks, Paddock made gambling transactions worth tens of thousands of dollars, though it was unclear whether they were wins or losses, NBC News reported, citing unnamed law enforcement officials.
Local media said he had also previously lived in Reno, Nevada, California and Florida.
Public records point to an itinerant existence across the American West and Southeast: A few years in California, a few years in other parts of Nevada.
Paddock had a hunting licence in Texas, where he lived for a while. He got his pilot licence, and had at least one single-engine aircraft registered in his name.
He also had a hunting licence for Alaska, where hunting for big game like elk and bear is popular.
In early 2015, he bought the modest two-storey home in the new housing development of Babbling Brook Court for retirees on the dusty edge of Mesquite.
He lived in the property with Marilou Danley, 62, records show.
US media reported that she was travelling outside the country and had no connection with the attack.
"It's a nice, clean home and nothing out of the ordinary,"Quinn Averett, a Mesquite police department spokesman, told reporters yesterday. Some guns and ammunition were found inside, though nothing remarkable in a region where gun ownership is high.
An hour's drive southwest is Las Vegas, where Paddock checked into a 32nd-floor room at the Mandalay Bay Resort and Casino last Thursday with at least 10 rifles for a shooting spree that would kill least 58 people and hurt more than 500.
The FBI said he had no connection with international militant groups.
Paddock took his own life before police entered the hotel room.
Security officials earlier said Paddock appeared to have been working alone, and his brother told US media he had no known religious affiliation.
"Nothing. No religious affiliation, no political affiliation, he just hung out," Eric Paddock told CBS.
Eric Paddock told media the family was shocked by the shooting.
"It's like an asteroid just fell on top of our family," he told the Las Vegas Review-Journal. "We have no idea how this happened."
