The sisters of Marilou Danley - Stephen Paddock's girlfriend - said they believe the Las Vegas shooter sent her out of the country so she wouldn't interfere with his plans to kill almost 60 people, Australian media reported Wednesday. She said she didn't hear or see anything while the event took place.
Danley's sisters maintained that she had no involvement in her boyfriend's murderous plot, which left 58 dead and more than 500 wounded.
The ATF said Paddock had 24 guns in his hotel room, and 12 of them had bump fire stocks, an attachment that helps a semi-automatic rifle mimic the shooting pace of a machine gun.
Investigators reached Marilou Danley early Monday but do not believe she was involved in the shooting at this time.
"It never occurred to me in any way whatsoever that he was planning violence against anyone", she said. "In that sense, I thank him for sparing my sister's life".
A police official in Manila, the Philippines capital, and a law enforcement official in the United States, both speaking on condition of anonymity, told Reuters that Danley was being met by Federal Bureau of Investigation agents in Los Angeles. It was not clear who or what exactly the money was for.
"I know that she don't know anything as well like us", one of the sisters said to 7 News.
She returned late on Tuesday from a family visit to the Philippines.
Ms Danley also explained why Paddock had wired her $100,000, an issue United States authorities had been open about investigating. She flew from Manila to Hong Kong on September 22 and returned to Manila on September 25 before flying to Los Angeles Tuesday.
At a live press conference on October 3, Clark County Sheriff Joe Lombardo announced the news.
On Sunday night, Stephen Paddock, 64, went on a shooting rampage, killing 59 people and wounding more than 400 in Las Vegas.
An official with Las Vegas' McCarran International Airport said "an airport perimeter fence near the concert venue was breached by people fleeing the scene of the incident", and airport staff "transported those people to the designated evacuation site".
