SALT LAKE CITY (AP) — The Latest on the death of a Utah worker who disappeared during a manhunt for a father and son accused of kidnapping.

Police say they've found the truck that a slain rail line worker was driving when he disappeared during a manhunt for a father and son accused of a Utah kidnapping.

The Sublette County Sheriff's Office in Wyoming says an FBI agent spotted the pickup from the air Thursday as crews searched near the suspects' remote hideout in that state.

The discovery comes after the body of 63-year-old Kay Porter Ricks was found Tuesday night along the route Flint Wayne Harrison and son Dereck James "DJ" Harrison likely took as they fled to Wyoming.

Ricks vanished a few miles from where police believe the Harrisons were lying low after tying up a woman and her four teenage daughters in a Utah basement. The women escaped.

The Harrisons have been arrested, and police are investigating if they were involved in Ricks' death.
