In this preview video, Rick Heltebrake explains what happened when Christopher Dorner carjacked him before the gunman fled to a cabin in the woods on Tuesday.
"I realized it was Christopher Dorner and I saw a vehicle crashed in the snow behind him, and he came up to the window of my truck, my driver window, with his gun pointed at me and he said, 'I don't want to hurt you. Just get out, start walking and take your dog."
