Authorities are searching for leads in the disappearance of a Montana teenager who has not been seen since New Year’s Day.

Selena Not Afraid, 16, was last seen on January 1 at a rest area between Billings and Hardin along Interstate 90 in Montana. According to the Billings Gazette, people who had been driving Selena home after a New Year’s Eve party told police that they left her at the rest stop after the van they were driving broke down, but reportedly later restarted.

Selena is a student at Hardin High school and a member of the Crow Nation. Her relationship to the people who were driving her on January 1 is not known.

According to USA Today, multiple agencies have joined in the search, including the FBI’s specially trained child abduction team.

When last seen, Selena was reportedly wearing a gray sweater, blue jeans, a black coat, and gray ankle boots.

Anyone with information about Selena’s disappearance is asked to call Big Horn County Sheriff’s Office at 406-665-9780 or call 911.
