Update 10:28 p.m.
The search for Big Horn County teen Selina Not Afraid was suspended at dark on Thursday night.
Family, friends, search and rescue teams and volunteers took to the air, horseback and on foot in a three-to-five mile radius at the rest stop on I-90.
Not Afraid, 16, was riding in a van from Billings to Hardin on New Year’s Day.
The driver of the van fixed a mechanical problem, according to Big Horn County Sheriff Pete Big Hair.
The driver took off with three passengers, leaving Not Afraid and another woman behind because he was concerned the van would stall again.
That driver called his mother to pick up the woman and Not Afraid, who was not there.
“There’s about two or three different stories from these people in the vehicle,” Big Hair said. “They’re not all in one story. There’s different stories from a couple of them. We kind of don’t know if they’re telling the truth or not. So that’s why we want to verify.”
He said the Big Horn County investigators want to hear from the two men and three women that were in the van with Not Afraid.
Three are from Billings, so the FBI and the Billings police will help with interviews.
Big Hair also said investigators searched the van and found “nothing suspicious.”
Update 8:38 p.m. The Missing Endangered Person Advisory has expired, but Not Afraid has not been found.
Searchers are continuing to look for her.
