Sheriff Joe Lombardo again expressed frustration with the pace of the investigation, but not with the investigators who have yet to pinpoint the motive behind the shooter's decision to fire from the 32nd floor of the Mandalay Bay hotel casino on a Las Vegas Strip concert crowd of 22,000 on October 1. "That looked straight out of a movie, you know?" In addition, Paddock brought them in 2015.
In addition to being an avid gambler and gun enthusiast, 64-year-old Stephen Paddock loved to travel and has been on 20 different cruises, investigators say, including to areas of Europe and the Middle East.
A lawyer for Paddock's Australian partner, Marilou Danley said she "continues to co-operate fully with the investigation". After Jesus Campos, a hotel security guard, took fire on the 32nd floor - Paddock blasted rounds through his door - officers headed up the stairs and found the barricaded stairwell door.
The city of Las Vegas honored the victims of the shooting Sunday night by darkening its famous Las Vegas Boulevard for 11 minutes, the length of time of the attack.
The gunman who killed 58 people in the deadliest mass shooting in modern USA history targeted aviation fuel tanks, stocked his auto with explosives and had personal protection gear as part of an escape plan, authorities said Monday.
McMahill said Campos provided critical information on the location of the suspect.
Saying they could find "no known nexus" to suggest Paddock was acting on behalf of Islamic State, Las Vegas police confirmed he was alone in room 32135 of the Mandalay Bay casino when he opened fire last Sunday night.
Investigators are speaking to Paddock's relatives and to his girlfriend, Marilou Danley, who returned to the country after the shooting and was interviewed by the Federal Bureau of Investigation.
"It's because this individual purposely hid his actions leading up to this event, and it is hard for us to find the answers to those actions", Lombardo said.
Publicly, investigators have said they are struggling to establish a motive for the massacre. "Nearby him that was on the ground consistent with him shooting himself" Joshua Bitsko added.
"I can assure we are aware of all aspects of this case to include the rumour, innuendo and suppositions by many in the public".
Praised by the interviewer for reaching Paddock in 12 minutes, the sherriff responded: "During a critical incident, 12 minutes is a long time". The officers explained to CBS that this appeared to be calculations of shooting trajectory to the crowd nearby.
In the CBS interview images of Paddock's body were shown and the officers described finding his body after blowing open the bullet-hole ridden doorway to his room.
Between laptops, phones, drills, drill bits, tools, electrical wiring and a note with numbers signifying altitude, distance from the crowd and bullet drop, the room painted one clear picture: Paddock had planned this for some time. "We want to figure out the why to this, and we'd like to know the motive".
"I wanted to make sure somebody wasn't hiding between the windows and the curtains".
