Gunmanâs girlfriend said she was unaware of the plan.
In her first public statement since the shooting, the gunmanâs girlfriend said on Wednesday that he had sent her on a trip to the Philippines and wired her money there, but that she did not know he had been planning to harm anyone.
The statement from the woman, Marilou Danley, which was read by her lawyer, Matthew Lombard, came after Ms. Danley went to the Los Angeles offices of the F.B.I. for questioning, according to a law enforcement official. It was released as the authorities sought her insight into what prompted a man with no evident criminal history to become a mass murderer.
She stressed that she returned to the United States voluntarily, âbecause I know that the F.B.I. and the Las Vegas police department wanted to talk to me, and I wanted to talk to them.â
âHe never said anything to me or took any action that I was aware of, that I understood in any way to be a warning that something horrible like this was going to happen,â she said.
The gunman booked accommodations near another festival.
The gunmanâs motive remains unknown, Sheriff Lombardo said. Despite the meticulous planning that went into the attack, the gunman left behind few obvious traces, with no social media footprint to examine or manifesto to be pored over, he said.
The sheriff indicated that Mr. Paddock may have blended in intentionally, hiding the urge to violence that drove him to one of the deadliest mass shootings in modern United States history.
âAnything that would indicate this individualâs trigger point, that would cause him to do such harm, we havenât understood it yet,â the sheriff said.
Mr. Lombardo said that a few days before the shooting, the gunman took another set of rooms in a high-rise building near another music festival. Through Airbnb, he rented a unit in the Ogden, a condominium building in downtown Las Vegas with a view of the Life is Beautiful festival, held from Sept. 22 to Sept. 25.
At least three of the rifles Mr. Paddock had in his luxury suite on the 32nd floor of the Mandalay Bay Resort and Casino were equipped with scopes. Twelve of the rifles were outfitted with bump stocks, devices that enable the weapon to be fired as rapidly as a machine gun, shooting hundreds of rounds per minute, which may explain how he was able to rain such devastation on the crowd below, law enforcement officials said.
The president met with victims of the attack.
President Trump spent four hours in Las Vegas on Wednesday, during which he paid tribute to the professionalism of the doctors who treated the shooting victims. He said that meeting with the patients at one hospital made him âproud to be an American.â
The president said he met with some âabsolutely terribly woundedâ patients and hailed their bravery during the horrific attack Sunday night. He said many of those he met had been wounded as they sought to help others amid the hail of bullets.
