Marilou Danley, a woman who was wired $100,000 by Stephen Paddock before he fired on a country music concert in Las Vegas, remains a person of interest in the investigation into the shooting, the Las Vegas Police Department said Tuesday.
Paddock transferred $100,000 to the Philippines in the days before the shooting, a USA official briefed by law enforcement but not authorized to speak publicly because of the continuing investigation told the AP on condition of anonymity.
It's not clear at all what, if any, information she might be able to provide. Fifty-eight people were killed and more than 500 were wounded in the attack. Paddock reportedly killed himself as officers closed in on the hotel room he had chosen to carry out the attack.
She was expected to be questioned upon her arrival in Los Angeles, the New York Times reported.
"But obviously that investigation will continue", Clark County Sheriff Joe Lombardo said.
Danley described herself on her now-disabled Facebook as a "proud mom and grandma who lives life to the fullest".
The Australian Associated Press reported that Danley was born in the Philippines and moved to Queensland in eastern Australia in the early 1980s.
Law enforcement authorities are hoping to obtain some answers from Danley, who has been identified as Paddock's live-in companion.

I don't think it's a serious problem because he stopped before it will become a serious injury. He said he would prefer to stop and not risk a bad injury.
Marilou Danley has "questions to answer" when she returns to the United States, police say.
No motive has emerged yet for the deadly shooting spree by Paddock, a wealthy, 64-year-old retired accountant who liked to gamble for high stakes and owned a comfortable home at a golf course retirement community near Las Vegas.
Reynaldo Bustos, her brother, told ABC News that he spoke to his sister following the shooting.
Paddock had recently wired $100,000 to the Philippines, a USA law enforcement source confirmed to CNN.
The closest Paddock ever appeared to have come to a brush with the law was a traffic infraction, authorities said.
They lived together in Mr Paddock's property in Babbling Brook Court, a two-bedroom home worth $396,000 (£297,554).
Police are not aware whether the devices were transmitting - the FBI is investigating their use - but the Clark County sheriff told reporters he thinks the shooter might have used them to watch for people approaching his room.
"It just makes less sense the more we use any kind of reason to figure it out", Eric Paddock said in a text message on Tuesday. Police said they're investigating the source of the leaked photos.
Public records on Paddock point to an itinerant existence across the US West and Southeast, including stints as an apartment manager and aerospace industry worker.
