The FBI says the shooter who killed 58 people and injured more than 500 others at a Las Vegas concert had no connection to an global terrorist group.
The woman said Danley is "a good person" who would've stopped Paddock had she been there.
Ms Danley was seen in a wheelchair after landing back in the US.
Travel records obtained by ABC News show Danley, who uses an Australian passport, traveled to her home country of the Philippines on September 15. She is an Australian citizen. Lombardo stated that Danley was out of the country when Paddock carried out his attack but that he anticipated she would provide information that would help investigators to determine the gunman's motivation.
"It never occurred to me in any way whatsoever that he was planning violence against anyone", Marilou Danley said.
Sources tell CBS News that it's unclear whether the money went to Danley or to her family in the Philippines. A law enforcement official says she arrived on a flight from Manila to Los Angeles where Federal Bureau of Investigation agents were waiting for her late Tuesday night.
The police chief also said a thorough search on related data on Mr. Paddock's affairs have shown no link with local or worldwide terrorists.
Police found Stephen Paddock to be a man with no criminal record, but he had about 40 rifles in his possession in several locations.
Swat officers then broke down the door and swarmed the room, where they found Paddock dead.
The Clark County Sheriff Joseph Lombardo said that he believed there was evidence Las Vegas mass murderer Stephen Paddock may have had additional plans after his gun rampage Sunday night.
Some 22,000 people were in the crowd when Paddock opened fire, sparking a panic in which some people trampled on others in their desperate bid to escape.
Some of the 59 victims of the shooting.
After the disgusting massacre at a Las Vegas music festival on Sunday night that killed 58 and wounded hundreds more, concerns emerged immediately about other sites that could be vulnerable to a similar attack. Dozens remain in critical condition. Authorities also want to know why Paddock wired $100,000 to an account under Danley's name in the Philippines the week before the massacre.
ABC News said that Paddock's financial history may provide a key to his motive.
He said there could be a genetic component to the slaughter: Paddock's father was a bank robber who was on the FBI's most-wanted list in the 1960s and was diagnosed as a psychopath.
