Identity Crisis

A train with 184 passengers derailed and crashed high in the Colorado mountains on a cold December day in 2001. No one survived but one young man. He had been thrown across a ravine and landed on a flat rock, unconscious. When he regained consciousness, he discovered he had amnesia. He didn't know where he was, where he came from, or where he was going. He didn't know his name and had lost all of his identification and money during the wreck. During the next couple of days, he worked his way down the mountain until he found a small town. He tried to get work at different businesses in town but was unsuccessful. During the months that followed, as he struggled to survive and search for his identity, he encountered people of many different backgrounds. He punished some people, destroyed a drug ring, exposed the Mob, dealt with street thugs, and helped police catch a gang of thieves. He helped many other people: an old lady with little money, an abducted and abused girl, two mothers living in a homeless shelter, a destitute woman, and a distraught special-needs girl. He also saved one man's company and another man's ranch. All the people who met this unknown man were amazed at the deeds he preformed, the people he helped, and the crooks he destroyed, all while going through an identity crisis. Who was this man?
