Colorado City teenager Hailey Dunn has been missing since Dec. 27. The story has gone through twists and turns ? from the Jan. 11 release of affidavits pointing toward suspect Shawn Adkins, to featured appearances on the ?Nancy Grace? show and images of law enforcement searching several landfills. Law enforcement and volunteers have been searching for weeks.

Through the first four weeks, no one has been arrested, and officials said more evidence is needed to determine a crime has been committed. Hailey's parents remain hopeful Hailey may be missing ? and not harmed.
