Meanwhile, another person who claims to be the niece of Stephen Paddock posted to Facebook a short time ago.

The poster, who is identified as Nicole Paddock, says that Stephen Paddock is her uncle whom she didn't see often.

The woman who lives in Orlando claims that, "Sometimes I would see him in Las Vegas when I was there vising other family, but these encounters were casual and infrequent. I cannot speak to what possibility motivates someone to do something like this nor what his specific motivations may have been. He never came across as religious or political."
