Watch Chris and Jim recount their amazing escape.
Before he started running, Chris says he felt a moment of hesitation. "As I was lying on the floor, I just said: 'I am not ready to die. This is not the way I'm going to die. I have a lot more to do.' We counted down, and Jim looked at me and I looked back at the gunman and he looked down," he says. "I just turned and ran the fastest I think I've ever run."
While Chris made a dash to door, Jim thought his fellow hostages were executing a different plan. "When [Chris] takes off, I actually took off for cover behind one of those pillars for a second. A voice in my head said, 'Run.' By then, the gunman had come around the desk and I booked it."
After all three hostages made it to safety, a sniper shot and killed Lee.
