Marilou Danley, who was in the Philippines since September, was living with Stephen Paddock and authorities were hoping before her arrival that she would agree to be interviewed. Both the police and Danley's sister have helped piece together the circumstances that led to her being overseas when Paddock killed at least 59 people and injured more than 500 more.
"It never occurred to me in any way whatsoever that he was planning violence against anyone", she said in the statement. They believe Paddock sent her away so she wouldn't interfere with his plans.
Danley was met by Federal Bureau of Investigation agents at the Los Angeles airport late Tuesday, according to a law enforcement official who spoke to The Associated Press on condition of anonymity. They expressed gratitude that she is alive but said that doesn't make up for what happened.
Snyder said the bump stocks "simulate automatic fire", though she didn't identify which firearms from Paddock's arsenal of rifles, shotguns and handguns were used in the shooting. The FBI said it had found "no connection" between the shooter and an extremist group.
"Maybe he's a super guy that was working this all out on his own, but it would be hard for me to believe that", the sheriff said.
Ms Danley assured her family she has a "clean conscience" following Sunday night's rampage, her brother told the US's ABC News in the Philippines.More news: Simona Halep secures long-awaited win over Maria Sharapova
"She was sent away".
"Assuming she had no role in his actions, the most important thing is any light she can shed on Paddock's motive", said one official, who spoke about the continuing investigation only on condition of anonymity. "In that sense, I thank him for sparing my sister's life but that won't be to compensate the 59 people's lives".
Using an Australian passport, Danley travelled to her home country Sept. 15, then flew from Manila to Hong Kong Sept. 22, where she stayed for three days before returning to Manila Sept. 25.
Sometime prior to the shooting - an exact date is not yet known - Paddock wired $100,000 to the Philippines.
As fresh details of the meticulous planning of the massacre were revealed by investigators, Sheriff Joseph Lombardo of Clark County, told a press conference that detectives were in contact with Marilou Danley, who had been travelling in the Philippines at the time of the shooting.
