The Las Vegas shooter's girlfriend says she had no knowledge of any plans by him to commit a massacre - and says he was a "kind, caring, quiet man".
Marilou Danley's lawyer read out a statement from her after she met with FBI officers.
"I knew Stephen Paddock as a kind, caring, quiet man," Danley's statement said.
"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."
Danley said that she left the country because Paddock bought her a ticket to visit her family in the Philippines.
While there, she said, Paddock wired her money that he explained was meant to help her purchase a home for Danley and her 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," she said.
"It never occurred to me in any way whatsoever that he was planning violence against anyone."
Danley, who pledged to cooperate with authorities, is viewed by officials as a key part the investigation into the deadliest mass shooting in modern American history.
Paddock brought a small arsenal into a two-room suite on the 32nd floor of the Mandalay Bay Resort and Casino and began raining bullets on the thousands of concertgoers far below.
Authorities have described a chilling level of preparation but have been unable to discern a motive for the shooting.
Paddock, who had set up cameras so he could monitor the approach by police, turned a gun on himself as a SWAT team closed in.
Danley's lawyer Matthew Lombard said she plans to cooperate fully with the investigation.
He spoke in Los Angeles after Danley met with FBI agents to discuss Sunday's carnage on the Las Vegas strip.
She returned to the U.S. Tuesday night from the Philippines, where she was visiting family.
Marilou Danley's statement in full
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.
I have faith in God and I will continue to pray for everyone who has been harmed or hurt. I am a mother and 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 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 cooperating with the authorities. I voluntarily flew back to America because I know that the FBI and the Las Vegas Police Department wanted to talk to me and I wanted to talk to them.
I will cooperate fully with their investigation. Anything I can do to help ease suffering and help in any way, I will do. Please respect my privacy and my family's privacy.
