Authorities also found thousands of rounds of ammunition in Paddock's Mesquite home, and an ingredient used in explosives was discovered inside the killer's auto.
Paddock killed 59 people and wounded hundreds more at a country music festival near his hotel.
The Las Vegas gunman's girlfriend, back in the United States after a weeklong trip overseas, will be at the centre of the investigation into the shooting deaths of 59 people as authorities try to determine why Stephen Paddock, a man with no known record of violence or crime, would open fire on a concert crowd from a high-rise hotel.
A total of 47 guns have been recovered from three locations: Paddock's hotel room and his two Nevada homes in Verdi and Mesquite. Paddock killed himself in the 32nd floor hotel room he used as a vantage point to rain bullets down on people attending the Route 91 Harvest festival.
The previous weekend, Paddock had rented a high-rise condo in a building that overlooked the Life is handsome alternative music festival featuring Chance the Rapper, Muse, Lorde and Blink-182, said Lombardo, who offered no other details about what led Paddock there.
Sheriff Joseph Lombardo of the Las Vegas Metropolitan Police said at Wednesday night's press conference. But if someone wants to build up acache of rifles the way Paddock did, they could do so without anyone noticing.
"She probably was even more shocked than us, because she is closer to him than us", her sister said.
State Department Issues Cuba Travel Warning Over Sonic Attacks
In the meanwhile, the Department has ordered all USA nonemergency government employees and their families to leave the island. Today (Sept. 29), the Department of State released an official warning against travel to Cuba after several U.S.
Investigators say that the shooting rampage was meticulously planned and included specially modified weapons.
She says he wired her money while she was there to buy a house for herself and her family. "So unnecessary. Who can believe what happened to Las Vegas?".
"The woman said Danley is "a good person" who would've stopped Paddock had she been there".
Danley, 62, who travels on an Australian passport, arrived in the Philippines from Tokyo on September 15, then left for Hong Kong on September 22 and flew back to the Philippines on September 25, said Maria Antoinette Mangrobang, a spokeswoman for the Philippine Bureau of Immigration. "He never cared about any of that stuff", his brother, Eric Paddock, said outside his Florida home. She was overseas at the time and is not believed to be involved.
"Australia will support the United States authorities in their investigation in whatever way we can, but we have not had contact with Marilou Danley directly". When officers entered the hotel room, they found Paddock dead.
She said she was initially pleased when Paddock wired her money in the Philippines to buy a house for her family, but she later anxious it was a way to break up with her.
"She didn't know she was going to the Philippines until Steve said "Marilou I found you a cheap ticket to the Philippines", one of her emotional sisters said".
