Nampa carjacking suspect Rodney Seiber was arrested Wednesday in Montana, Nampa police Sgt. Tim Randall said.
Randall said authorities in Big Horn County received a report of a stolen four-wheeler and located it at the end of a ravine. They suspected Seiber may have stolen it, and a search ensued.
A search team located the Nampa man in an old outbuilding behind a ranch, Randall said, and a cold, hungry Seiber gave up without incident.
Earlier, Little Big Horn College in Crow Agency was on lockdown after the 36-year-old Seiber was believed to have been spotted on the Crow Indian Reservation, The Billings Gazette reported. He was believed to be armed.
College President David Yarlott said he ordered the lockdown at 2 p.m., but was lifting it about an hour later after authorities said the suspect had moved south of town. The lockdown affected about 200 students.
Officials had been looking for Seiber since Sept. 18 when he was suspected of threatening a welding supply company employee with a knife in Nampa before taking a company van. Seiber disappeared into a cornfield after the van crashed.
He turned up in Montana on Monday, where he fled officers after a motel in Hardin called in a trespassing complaint.
His 18-year-old girlfriend, Brittany Robbins of Caldwell, was arrested for trespassing and obstructing.
Seiber has previous felony convictions, including grand theft, battery on a correctional officer and unlawful possession of a firearm, officials said.
Family members had told Nampa police that he knows this is his "third strike" and he "is not going back to prison." Nampa police Sgt. Tim Randall said Seiber has threatened suicide or suicide by police.
