Sublette County Sheriff Stephen Haskell said Friday that firearms and knives Flint Wayne Harrison and his son Dereck James "DJ" Harrison were believed to have had were unaccounted for.
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.
No connection has been established to the two Utah men held in the Sublette County Jail on kidnapping and assault charges back in Utah, but the man's pickup truck is missing, and the investigation continues.
Authorities are expected to ask 51-year-old Flint Wayne Harrison and his 22-year-old son Dereck James "DJ" Harrison to agree to be returned to Utah to face kidnapping, drug possession and other charges.
