However, police found a cryptic note in Paddock’s room on the 32nd floor of the Mandalay Bay Resort and Casino. Las Vegas Metropolitan Police Department Undersheriff Kevin McMahill confirmed investigators found a piece of paper with a series of numbers written on it. He said Friday afternoon that police have yet to determine “what those numbers are or mean.” “In the past, terror attacks or mass murder motive was made very clear by a note that was left, by a social media post, by a telephone call that was made, by investigators mining computer data,” Undersheriff McMahill said. “Today, in our investigation, we don’t have any of that uncovered. I wish we did. We will and are continuing to investigate with great tenacity and hope to arrive at an answer,” he added.

As for if Paddock worked alone or had an accomplice, Undersheriff McMahill said he was “confident… there was not another shooter in that room. “What I cannot confirm to you today, and what we continue to investigate, is whether anybody else may have known about this incident before he carried it out.” RELATED GALLERY: Mourners Hold Emotional Vigil in Las Vegas to Remember Off-Duty Cop Who Was Killed in Mass Shooting Investigators have already interviewed Paddock’s girlfriend, Marilou Danley, after naming her a person of interest.
