Las Vegas: The girlfriend of the Las Vegas gunman says she thought her "kind, caring, quiet" partner was trying to break up with her when he bought her a plane ticket to the Philippines two weeks ago and wired her $US100,000 ($127,000) to buy a house in her home country.
Marilou Danley, 62, arrived in the US from the Philippines on Wednesday night and has been with the FBI for more than 15 hours.
Her boyfriend Stephen Paddock, a retired accountant and multi-millionaire gambler, killed 58 people and injured more than 500 when he fired on a crowd at the Route 91 Harvest country music festival from his 32nd floor room at the Mandalay Bay hotel on Sunday night, local time. He shot himself dead shortly before police stormed into his hotel room.
He had 47 guns, 33 of which were accumulated over the last year, the Federal Bureau of Alcohol, Tobacco and Firearms said.
Ms Danley made her first public comments on Thursday via a statement read out by her lawyer, Matt Lombard, outside the FBI's offices in Los Angeles.
"I am devastated by the deaths and injuries that have occurred and my prayers go out to the victims and their families and all those who have been hurt by these awful events," the statement said.
"I have faith in God and I will continue to pray for everyone who has been harmed or hurt. I am a mother and a grandmother and my heart breaks for all who have lost loved ones.
"I knew Stephen Paddock as a kind, caring, quiet man. I loved him and hoped for a quiet future together with him. He never said anything to me or took any action that I was aware of that I understood in any way to be a warning that something horrible like this was going to happen.
"A little more than two weeks ago, Stephen told me that he found a cheap ticket for me to the Philippines and that he wanted me to take a trip home to see my family. Like all Filipinos abroad, I was excited to go home and see family and friends.
"While there, he wired me money which he said was for me to buy a house for me and my family. I was grateful but honestly I was worried that first the unexpected trip home and then the money was a way of breaking up with me. It never occurred to me in any way whatsoever that he was planning violence against anyone.
"I have not made a statement until now because I have been co-operating with authorities and I voluntarily flew back to America because I knew that the FBI and the Las Vegas Police Department wanted to talk to me and I wanted to talk to them. I will co-operate fully with their investigation. Anything that I can do to help ease the suffering, I will do."
Ms Danley, who lived with Paddock in an over-55s community in Mesquite, Nevada, was travelling on an Australian passport but moved away from Queensland more than 15 years ago.
In the immediate aftermath of the shooting, her image was broadcast around the world, sparking a global manhunt after it was revealed she had lived for years alongside Paddock. It's understood her casino playing card was located in Paddock's hotel room.
After three days, there is still no indication of why Paddock carried out the shooting and investigators have been hoping that Ms Danley may be able to shed light on a motive. Paddock has no known online footprint, left no notes, had no prior interactions with authorities and was not close with any friends or family.
He has been described as an anti-social and eccentric gambler who had upped his stakes in recent weeks, gambling more than $US10,000 a day.
After her questioning, FBI Special Agent in Charge Aaron Rouse said was no evidence at this point to indicate that the mass shooting in Las Vegas this week was terrorism.
