A dazed man was found wearing only boxer shorts and a sock four days after being removed from an Amtrak train in Arizona for unruly behavior, authorities said. Roosevelt Sims, 65, was incoherent when he was found Thursday night in a forested area about a mile from the train stop. "I think he was really confused and disoriented about where he was," Lt. Mark Christian of the Coconino County Sheriff's Office said Friday. Sims, of St. Louis, reportedly was headed to Los Angeles to visit family. An Amtrak spokesman said Sims was escorted off the Southwest Chief train Sunday night after he began acting strangely and refused to calm down. "The person was reported by our conductors to be unruly, disruptive and unwilling to take direction from the conductor to bring his behavior to a level that was not disruptive," said Amtrak spokesman Marc Magliari, who added that the company followed standard procedure.
