No motive yet in the Las Vegas massacre, but it doesn't mean investigators aren't learning more about the man responsible.
Police are poring over the Las Vegas gunman’s actions leading up to Sunday’s shooting, hoping to find some kind of clue that could explain what happened. Officials now say Stephen Paddock previously rented another room in Vegas during another music festival in mid-September. Paddock had also specifically requested an upper floor for his suite at the Mandala Bay hotel. He brought nearly two dozen firearms, plus thousands of rounds of ammunition and his possession of so many guns in the room and at his two properties, as well as the transport of such a large amount of equipment is troubling authorities. Paddock’s girlfriend was interviewed for hours upon her reentry to the United States, denying any involvement in the planning of the massacre. Investigators admit they haven’t gotten much closer to a motive.
