Clemente said a "psychological autopsy" may be necessary to try to establish the motive.
Investigators, at a loss to determine a motive for Sunday's bloodshed, have focused on Danley, who had shared Paddock's retirement community condo in Mesquite, Nevada, northeast of Las Vegas, before leaving the United States for the Philippines in mid-September. "Anything I can do to help ease suffering and help in any way, I will do".
A journalist in the press pool asked whether Paddock had planned to use the vehicle to escape, but Lombardo declined to answer. On Oct. 3, two days after the shooting, Danley returned to the U.S. met by federal agents.
Why did he continue firing with an arsenal of weapons for nine to 11 minutes? Still, the sister left open the possibility that the interview would be helpful to investigators.
"The fact that he had the type of weaponry and the amount of weaponry in that [hotel] room - it was preplanned extensively", Lombardo said.
The gunman's brother, Eric Paddock, said he was "completely befuddled" by his brother's actions. Investigators also learned Paddock accompanied Danley on a previous trip to her home country.
Some investigators turned their focus Tuesday from the shooter's perch to the festival grounds where his victims fell.
Praising the bravery of first responders and seeking to comfort the families of victims during his final address of the day, Mr Trump said: "We know that your sorrow feels endless".
Her sisters in Australia have since told 7 News they believed he "sent her away" to the Philippines prior to the shooting. There she met Paddock, a high-limit player. Social media and other reports say she is a mother and a grandmother who divorced from her previous husband in 2015. "He was a sick man, a demented man", US President Donald Trump said. "The wires are screwed up".
"I know she has to be devastated about what has happened", Dionne Waltrip said, adding that the family, which now lives in Arkansas, has been receiving death threats after her father was erroneously identified online as the shooter. "We're defined by our love, our caring, and our courage".
News reports said it was for her life insurance. "Americans dashed into a hail of bullets to rescue total strangers". He was likely monitoring foot traffic in the hallway.
Officials said Paddock purchased 33 weapons since October 2016 - most of them rifles.
"Our family, and all our extended family, the Danleys, have been getting death threats", his daughter said. Look for him to say that bad guys will always find a way to get guns, and, perhaps, that more guns are needed to prevent lawlessness. They'll show him pictures of those they've lost, and tell him, sobbing, about the hopes and dreams that have been snuffed out.
The gunman opened fire on 22,000 people attending a music festival in Las Vegas from a room on the 32nd floor of a nearby hotel. One camera looked out the peephole on the suite's door.
Paddock shot himself inside his Mandalay Bay hotel room when it was stormed by a SWAT team at around 11pm on Sunday (7am Monday UK time).
But Trump ran his campaign with a strong pro-Second Amendment message and the backing of the National Rifle Association. After escaping from a prison in Texas in 1968, he was captured 10 years later and has since died, law enforcement officials told NBC News. Hickey was uncertain if Campos was armed.
Sonny was declared dead at the hospital. He then shot and killed himself.
"Mars just fell into the Earth", he said. And authorities found two gun stocks that could have let him modify weapons to make them fully automatic.
