Rebecca Wright: We may never know Vegas gunman's motives

Marilou Danley wasn't in the United States when her partner Stephen Paddock opened fire on a Las Vegas crowd, killing almost 60 people.

"I know that she don't know anything as well like us".

"She was sent away".

Baristas told the paper they would wince when Paddock came in with Marilou Danley, because he regularly belittled and berated her in front of customers and staff.

"I can't comment at the moment, I can't say anything", her sister Liza Werner told the Sydney Daily Telegraph, which said she was a grandmother.

The official said U.S. authorities were eager to question Danley, who described herself on social media websites as a "casino professional", mother and grandmother, about whether Paddock encouraged her to leave the United States before he went on his rampage. Paddock was using Danley's slot-machine card which investigators used to find her name. "Only Marilou can maybe help".

Authorities appeared to rule her out on Monday as it emerged that she was not in Las Vegas at the time of the killing.

She was met by Federal Bureau of Investigation agents at the airport in Los Angeles late last night.

It is not clear if the interrogation will take place in Los Angeles or Las Vegas.

The official, who has been briefed regularly on the probe but spoke on condition of anonymity, said the working assumption of investigators was that the money was intended as a form of life insurance payment for Danley.

"We have had a conversation with her and we believe her at this time not to be involved., Obviously that investigation will continue".

Ms Danley, 62, is expected to arrive in Las Vegas from the Philippines as early as Wednesday local time.

But police have also said that she is not a suspect, and only want to question her about Paddock.

She was in the Philippines when Paddock opened fire with high-power rifles from a 32nd floor hotel room Sunday night at a sea of concertgoers below on the famed Las Vegas strip.

Paddock's girlfriend has since touched down in the U.S. after flying from the Philippines to be interviewed by the FBI as part of the ongoing investigation.

He added: "We don't have authority over her [Danley] because the crime was committed in the USA".

Paddock's brother, Eric, has said he was mystified by the attack. "He escaped and (left) us here putting the puzzles together".

So far, police believe Paddock acted alone - which could make his motive harder to determine.

Police found another 19 firearms, explosives, and thousands of rounds of ammunition at Paddock's home in Mesquite, 82 miles northeast of Las Vegas.

Stephen Paddock's live-in gal pal Marilou Danley was married to two men simultaneously - and used two Social Security numbers, according to a report.
