The Ada County Sheriff's Office says Rodney Seiber, 36, ran away when the transport company's vehicle stopped to let him use the restroom Thursday night around 6:22 p.m on the Orchard Access Road along Interstate 84.
Officials say Seiber, who was shackled and handcuffed, was then last seen along Mayfield Road near exit 71 north of the Interstate.
At one point, Ada County Prosecutors say, Seiber brandished a knife and tried to get inside a vehicle. It's unclear how he managed to get a hold of a knife.
Police say they set up a perimeter, shut down traffic on the interstate, and began searching the area. They also sent a geocast message to homes in the area warning them that Seiber could be nearby.
Officials say that a few minutes after 7 p.m., Seiber walked out out from a brushy area and gave himself up to officers.
Police say he was taken to the Ada County Jail to be interviewed and booked on escape charges.
Seiber was arrested on Sept. 28 in an outbuilding near Garryowen on Montana's Crow Indian Reservation after fleeing Montana law enforcement officers for three days.
Officials had been looking for Seiber since Sept. 18, when he was suspected of threatening a welding supply company employee in Nampa before taking a company van. He fled into a corn field after the van crashed.
His whereabouts were unknown until a clerk at a Hardin motel reported trespassers on Sept. 23.
More information will be reported as it develops.
