Stephen Paddock lived in a tidy Nevada retirement community where the amenities include golf, tennis and bocce. He was a wealthy real-estate investor, recently shipped his 90-year-old mother a walker and liked to play high-stakes video poker in Las Vegas.

Nothing in his background suggests why he would have been on the 32nd floor of the Mandalay Bay Hotel and Casino with at least 17 guns on Sunday night, raining an unparalleled slaughter upon an outdoor country music festival below.

Law enforcement and family members could not explain what would motivate a one-time accountant with no known criminal record to inflict so much carnage. Paddock had apparently planned the attack in great detail, including showing up at the hotel with at least 10 suitcases.

"I can't even make something up," his bewildered brother, Eric Paddock, told reporters Monday. "There's just nothing."

At least 59 people were killed and nearly 530 injured in Paddock's attack on the Route 91 Harvest Festival, where country music star Jason Aldean was performing for more than 22,000 fans. It was the worst mass shooting in modern US history. The 64-year-old gunman killed himself in the hotel room before authorities arrived.

The Daesh group claimed responsibility, without offering evidence, but Aaron Rouse, the FBI agent in charge in Las Vegas, said investigators saw no connection to international terrorism.
