The staffer also told the newspaper that Paddock showed no signs of suspicious behavior, and speculated that the gunman may have carried the weapons into his room in one of his many suitcases during several trips at different times during the days before the deadliest shooting in USA history.
Marilou Danley's sisters say Paddock sent her to the Philippines two weeks ago and wired her more than $US100,000 ($A127,280) before he killed 59 people and wounded more than 500 as he fired from a 32nd floor casino hotel suite on Sunday night.
Clark County Sheriff Joe Lombardo, who has called her a "person of interest" in the attack, has said detectives "anticipate some information" from Ms Danley shortly.
As of midday Wednesday, there was no indication she was aware of Paddock's plans, the officials said. Atlantis said in a statement this week that she has not worked there for several years. NBC says that Danley traveled to the Philippines on September 25 via Hong Kong. Only Marilou can maybe help, ' a sister said. "She was away so that she will be not there to interfere with what he's planning", one of her sisters in Australia told local reporters. Reports say Paddock lived as a retired accountant and country music fan who possessed a fondness for gambling - an activity he enjoyed often.
"He manipulated her to be completely as far away from this and safe when he did this", Eric said. "In that sense, I thank him for sparing my sister's life but that won't be to compensate the 59 people's lives".More news: Yusuf Says Super Eagles Of Victory
"Danley arrived in the Philippines last month, and then there was a wire transfer to her account for $100,000 from Stephen", NBI spokesman Nick Suarez said.
"Here's the reason why: Put two and two together".
"She probably was even shocked than us because she was more closer to him than us", one sister said. A federal official said that she was supposed to be questioned about her arrival in the United States.
He toured the Las Vegas Police Department Command Center and the city's University Medical Center, where he met, among others, officer Tyler Peterson who was injured while responding to the shooting.
Lombardo said the investigation is proceeding cautiously in case criminal charges are warranted against someone else.
