The concierge told her to give them her ring, which was on the table. The robbers then dragged her out to hallway at the top of the stairs and that's when Kim realized they were armed.
"I was looking at the gun, looking down back at the stairs," she recalled. "I have a split second in my mind to make this quick decision. Am I going to run down the stairs and either be shot in the back—it makes me so upset to think about it—but either they're going to shoot me in the back or if I make it and they don't, if the elevator doesn't open in time or the stairs are locked, then I'm f--ked! There's no way out."
Afterward, they took her back inside the room. All the while, Kim was looking at the concierge and pleading with him to ask them to spare her life. "I have babies. Please, they can't understand me, but tell them I have babies at home," she begged. "Please, I have a family. Let me live!"
