UPDATE OCT 9 11 PM: Sheriff Joe Lombardo said a Mandalay Bay security officer was shot before the gunman opened fire on the concert crowd killing 58 people.
The sheriff called the change in the timeline a minute change, after originally indicating the security officer was shot during the rampage.
UPDATE OCT 9: After a second search of Paddock's home investigators are trying to piece together a motive for his fatal attack of innocent concertgoers on Oct. 1.
They believe Paddock had a severe mental illness that went undiagnosed. They also found information that alleges Paddock spent his final day gambling for multiple hours with an unidentified prostitute.
UPDATE OCT 8: The FBI and the Mesquite Police Department have executed a new search on the house where Stephen Paddock lived with his girlfriend, Marilou Danley.
The FBI wanted to take another pass at searching the house after they interviewed Danley, said Mesquite Police Chief Troy Tanner. Tanner says the feds are back in the house now, conducting searches, photographing and processing evidence.
ORIGINAL STORY: Officials still have no clear indication of what transpired in Stephen Paddock's life to lead to the massacre.
They remain hopeful that his longtime girlfriend Marilou Danley will fill in the missing parts of the story. Contact 13 has details on their contact with Danley since she returned to the U.S. Last night.
Marilou Danley flew to Los Angeles from the Philippines Tuesday night, and according to her attorney, she's been fully cooperating all day with the FBI and Metro Police investigators, telling them everything she knew about Stephen Paddock.
Her Los Angeles-based attorney, mMtthew Lombard, spoke for the first time on her behalf this afternoon saying, "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."
He said Danley knew Paddock as kind, caring and quiet and that he never did anything to indicate a warning. He recently sent her out of the country and wired about a $100,000 to her in the Philippines, which he said was for her to buy a house for herself and her family.
Lombard reading a statement from Danley said, "Honestly I was worried that at first, the unexpected trip home and 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."
Lombard did not answer any questions. Reporters tried to ask what Danley knew about all the guns authorities recovered from the couple's Mesquite home. And whether she's allowed to leave the country.
He ended his press conference with this statement from Danley: "I have been cooperating with the authorities and I voluntarily flew back to America because I know that the FBI and Las Vegas Police wanted to talk to me, and I want to talk to them. I will cooperate fully with their investigation."
Danley's brother told ABC News today in the Philippines that she assured her family she has a "clean conscience." Danley traveled with an Australian passport and Australia's Channel 7 interviewed her sisters today, who spoke on the condition of anonymity.
"I know that she don't know anything as well, like us. She was sent away. She was away so that she will be not there to interfere with what he's planning."
Another sister said, "No one can put the puzzles together, no one except Marilou, because Steve is not here to talk anymore, only Marilou can maybe help out."
The 62-year-old Danley was in a relationship with Paddock for a few years, reportedly meeting while she worked as a hostess at a Reno casino.
Former FBI agent Brig Barker says, "You're the average of the main five people that you spend time with, right? So that's part of building out those concentric circles around him. Looking at the individuals that he had most of his contact with. And that is critical."
One individual Paddock had contact with in the hours before the shooting rampage told ABC News she spent 16 hours serving him. Saturday into Sunday she watched him gamble for eight hours straight and he was still there when she left at 7:30 in the morning.
As Contact 13 reported earlier this week, he was playing high stakes video poker, which is in a separate "exclusive" section of the casino. The employee said Paddock seemed odd, but not that much odder than some others who stay up all night on those machines.
ABC News is also reporting that in the months before his deadly rampage, Stephen Paddock was "descending into madness." A deteriorating mental state that included significant weight loss, an increasingly slovenly physical appearance and an obsession with his girlfriend's ex-husband.
