Authorities say one of two men charged in the kidnapping and murder of a Utah train worker has died after apparently hanging himself in a Utah jail.

The Davis County Sheriff's Office said 52-year-old Flint Wayne Harrison was found hanging in his cell early Monday morning at the jail in Farmington, about 20 miles (32 kilometers) north of Salt Lake City.

The sheriff's office says the State Medical Examiner is investigating.

Harrison and his son, 22-year-old Dereck James "DJ" Harrison, are accused of abducting 63-year-old Kay Ricks in Salt Lake City and killing him in May in southwestern Wyoming.

The two were being held in Utah where they were set to stand trial this year on 16 separate drug and kidnapping charges. They were then expected to be transferred to Wyoming to face charges in Ricks' death.
