While investigators continue to sift through the evidence from Sunday's massacre on the Las Vegas Strip, the big question remains unanswered: What motivated Stephen Paddock to commit mass murder?

Paddock’s room on the 32nd floor of Mandalay Bay was littered with firearms. Cameras were placed strategically in the hallway and peephole of the door to monitor the arrival of police.

Detectives say they used a closed circuit TV recording from the concert venue to determine that the shooting started at 10:05 p.m. Sunday, three minutes earlier than originally thought.

The last shots were fired at 10:15 p.m., likely when a hotel security officer interrupted Paddock, who responded by shooting thru the door of his hotel room, injuring the officer.

At 10:17 p.m. the guard reported the shooting to Metro, which led responding SWAT officers directly to Paddock’s room.

At 11:20 p.m. officers forced their way inside and discovered Paddock’s body.

Speaking to Australian media, the sisters of Marilou Danley — Paddock's live-in girlfriend — describe him as quiet and unsociable. But by all accounts, they say, living a normal life in Mesquite, Nevada.

“No one can put the puzzles together, no one except Marilou because Steve is not here to talk any more. Only Marilou can maybe help.”

Danley arrived in Los Angles Tuesday night from the Philippines and was taken to FBI headquarters in Westwood, Calif., on Wednesday morning for questioning.

Defense attorney Matthew Lombard said Wednesday that Danley plans to cooperate fully with the investigation.

Detectives already know paddock wired $100,000 to the Philippines last week. But whether it was for Danley or her family remains unknown.

Her sisters say Paddock sent Danley out of the country in mid-September, surprising her with an airline ticket.

“What he's done here is spare my sister's life,” a sister said. “He sent her away so he can plan what he's planning without interruption.”

Police have also learned paddock rented a room at The Ogden in downtown Las Vegas the weekend before the mass shooting, possibly scoping out the Life Is Beautiful music festival.

All of it part of an ever-widening investigation as to what led to the horror at the Route 91 Harvest Festival.

Paddock's brother, Eric, told reporters none of it makes sense, not from the brother he knew.

“I hope they find, when they do the autopsy, that there's a tumor in his head or something,” Eric Paddock said. “Because if they don't, were all in trouble.”

According to the Bureau of Alcohol, Tobacco, Firearms, and Explosives, Paddock began stockpiling weapons in 1982 but went on a buying spree about a year ago, purchasing 33 firearms in the past year.

Sheriff Lombardo credited that officer with ending the massacre, as Paddock still had more than 1,600 unused rounds of ammo in his hotel room.
