A man who spent four days in a drainage tunnel in Utah after falling in and sustaining a compound fracture in his leg could lose the limb. Daniel Samuelsen fell 50 feet down the pipe while attempting to take a shortcut during a hike in the foothills east of Salt Lake City. After screaming for help for hours and waiting a further four days for rescue, Samuelsen splinted his leg with a piece of wood and managed to scoot out of the lower section of the tunnels, which deposited him by the side of a road. "I was near tears when someone finally stopped ... I was so happy to see somebody who cared about me to stop and realize I needed help," he said. Doctors at St. Mark's Hospital in Salt Lake City, where Samuelsen is being treated, said the broken leg is infected and may need to be amputated.
