Marilou Danley, who returned to the United States late Tuesday from a family visit in the Philippines and is regarded by investigators as a "person of interest", said the carnage unleashed by Stephen Paddock while she was overseas caught her completely unaware.
On 4 October, 2017, Paddock's girlfriend issued the statement via her attorney, Matt Lombard: "It never occurred to me in any way whatsoever that he was planning violence against anyone".
The unarmed security guard who approached Paddock's room, Jesus Campos, is being hailed a hero.
Stephen Paddock, the white terrorist who opened fire at a country music festival in Las Vegas that left 58 dead and over 515 injured, reportedly booked two hotel rooms overlooking Grant Park where Lollapalooza takes places.
Paddock had 1,600 rounds of ammunition in his vehicle, along with fertilizer that can be used to make explosives and 22.5kg of Tannerite, a substance used in explosive rifle targets.More news: Don't Worry About the Seattle Seahawks Early Season Struggles
"We don't have any immediately accessible thumb prints that would indicate the shooter's ideology or motivation", said FBI Deputy Director Andrew McCabe.
"I'm also confident that there were no other people in the room leading up to this event", said McMahill.
The officers were the first to see the body of Stephen Paddock, who had taken his own life, and an arsenal of at least 23 semi-automatic rifles - 12 of which were equipped with bump-stocks, or rapid fire devices - found inside his hotel room.
"We have been down each and every single one of these paths, trying to determine why", Undersheriff McMahill said. I wish we did.
MSNBC reported on Friday a mobile phone charger that did not match Paddock's phone was found in his Mandalay Bay suite and it appears the keycard for his room was used to open the door when his auto had left the casino vehicle park.
"You gotta make the assumption he had to have help at some point, and we want to ensure that's the answer".
