The then 13-year-old vanished from the small town in December 2010. Since that time, authorities and searchers have been trying to track her down.
Her mother and her boyfriend, the only named suspect in the case, have since moved out of the area.
Despite months of investigating, law enforcement appears to be no closer to finding the missing teen.
The following photos were recently released by Hailey's father Clint Dunn.
