LAS VEGAS • At first glance, it seemed Stephen Paddock, 64, was set for a quiet life in a desert retirement community near his beloved casinos where he bought a new home in 2015.
From there it was only an hour's drive to Las Vegas, where he would embark on the worst mass shooting in recent US history.
Public records point to an itinerant existence across the American West: a few years in coastal California, a few years in other parts of Nevada, Reuters reported.
Paddock had a hunting licence in Texas, where he lived for at least a few years. He obtained his pilot licence, and had at least one single-engine aircraft registered in his name.
In early 2015, he bought a modest two-storey home in a new housing development for retirees on the dusty edge of Mesquite, a small desert town popular with golfers and gamblers that straddles the Nevada border with Arizona.
"It's a nice, clean home and nothing out of the ordinary," Mr Quinn Averett, a Mesquite police department spokesman, told reporters yesterday. Some guns and ammunition were found inside, though this was nothing remarkable in a region where gun ownership is high.

An hour's drive south-west is Las Vegas, where Paddock would check into a 32nd-floor room last Thursday at the Mandalay Bay Resort and Casino with at least 10 rifles for a shooting spree that would kill at least 58 people and hurt over 400.
Mr Eric Paddock, the shooter's brother, said the family was "bewildered" as to what drove him to mass murder, saying in a telephone interview that the family would release a brief statement through the sheriff's office in Orlando, Florida, where some of the shooter's relatives live.
Mr Paddock said that there was "absolutely no indication he could do something like this", and that his brother had no political or religious affiliation.
Speaking from his home in Orlando, Mr Paddock said he and his brother, living on different coasts, did not speak that often.
He said his mother was "in shock" and struggling to cope with the news, the Daily Mail reported.
"Our family is okay, we are sitting in here in our house, hoping that everyone doesn't attack us," said Mr Paddock.
"My mother is 90 years old, lives down the street from me. We are just completely dumbfounded. You can imagine how this has affected her."
