The family of the Filipina-Australian girlfriend of Las Vegas mass-murderer she had nothing to do with Stephen Paddock's shooting massacre.
They say Paddock sent her to the Philippines two weeks ago and wired her more than $US100,000 before he killed 58 people and wounded more than 500 as he fired from a 32nd floor casino hotel suite on Sunday night.
Marilou Danley has now returned to the US and is being questioned by FBI agents.
She was named a person of interest and her image flashed on media reports around the world in the immediate aftermath.
The 62-year-old former Queensland resident left Australia in 1989 and lived with Paddock in Nevada.

Her sister who lives in Queensland says she is a good person and knew nothing about Paddock's plot to slaughter dozens of revellers at a country music festival on the Vegas Strip.
"He sent her away so that he can plan what he is planning without interruptions," her sister, whose name was not revealed, told the Seven Network.
"In that sense, I thank him for sparing my sister's life. But that won't be to compensate the 59 peoples' lives.
"No one can put the puzzles together. No one except Marilou. Because Steve is not here to talk anymore, only Marilou can maybe help."
Ms Danley's sister said she would have stopped the massacre if she knew it was going to happen.
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.
"I called her up immediately and she said, 'Relax, we shouldn't worry about it. I'll fix it. Do not panic. I have a clean conscience'," Reynaldo Bustos told ABC in Manila.
Ms Danley was born in the Philippines and moved to Queensland in the early 1980s before moving 28 years ago to the US where she worked in casinos.
