Las Vegas shooting: Gunman fired for 9 to 11 minutes

Multiple People Shot on Las Vegas Strip

Authorities say Paddock opened fire from the windows of his 32nd floor hotel room late Sunday, killing 59 people and wounding hundreds more at a country music festival. Police reportedly found him dead in a room on the 32nd floor of the hotel. She said experts who analyzed it said you can hear 90 gunshots in just 10 seconds.

Marilou Danley, the Filipina-Australian girlfriend of Las Vegas mass-murderer Stephen Paddock, is being interviewed by Federal Bureau of Investigation agents in Los Angeles.

Las Vegas police officially named Danley a "person of interest" at a Tuesday afternoon press conference.

"In that sense, I thank him for sparing my sister's life", she said, adding her sister was "really in love with Steve".

"She was sent away", one sister said.

Marilou Danley broke her silence on Thursday, a day after being flown from her holiday in the Philippines to Los Angeles for questioning.

Authorities reportedly found 23 weapons in 64-year-old shooter Stephen Paddock's Mandalay Bay hotel suite, to which he'd arrived by vehicle.

"The fact that he had the type of weaponry and the amount of weaponry in that room, it was pre-planned extensively, and I'm pretty sure he evaluated everything he did in his actions, which is troublesome", Sheriff Joseph Lombardo of the Las Vegas Metropolitan Police Department told reporters Tuesday.

Australian Foreign Minister Julie Bishop said her government was working with U.S. authorities but told CNN affiliate Sky News on Monday that Australia had had no contact with Danley directly.

No one knows why Paddock morphed from a retired accountant to the deadliest mass shooter in modern United States history.

Law enforcement sources tell ABC News that Paddock had wired tens of thousands of dollars to someone in the Philippines over the past few months.

"What we know is once we arrived up there, we had isolated this individual to the two rooms".

A gun shop owner in Mesquite, Nevada, confirmed to ABC News that he sold guns to Paddock, but he did not specify how many and whether they were the ones used in the shooting. "We are going to pay our respects and to see the police who have done really a fantastic job in a very short time", Trump said before leaving the White House.
