His girlfriend was with him once.
I don't get the significance. According to the article: "The worker said Paddock's girlfriend, Marilou Danley, who police named a person of interest in the case, also came in to the shop once. 'The only time we saw Marilou, Stephen was in the store looking around, talking to Chris and I guess she was in the car and she opens the door and says, "Are you done?" 'And he says, "Yeah, I'll just be a second," that was the only time we saw her. He was totally pleasant to her, just said "I'll be a second, no problem."'"
