Police in Las Vegas continue to investigate a possible motive behind the tragedy on the Vegas strip, in which 64-year old Stephen Paddock fired round after round on a crowd of concert goers, killing 59 and wounding more than 500 others.
Cops found 23 guns in the hotel room from where he fired those shots and another 19 inside his home about an hour away. There were also explosives and several thousand rounds of ammunition in Paddock's home.
Police are hoping to speak with Marilou Danley, Paddock's live-in girlfriend when she comes home from Tokyo, Japan. They aren't sure when she will be returning.
