A spokesman for the investigation into a missing 13-year-old West Texas girl says dogs searching one of three landfills turned up evidence in the case even as hope remains for her safe return.
Abilene is 70 miles east of Colorado City, where the girl went missing last month.
Kampfer says searchers also used cadaver dogs in the Colorado City and Snyder landfills.
Hailey was reported missing Dec. 28 by her mother, Billie Dunn. The woman's boyfriend, Shawn Adkins, said he last saw Hailey a day earlier.
No one has been arrested. Adkins has been named a person of interest in the case.
