Colorado City Police Chief John Bivins said his department has made three requests for an Amber Alert for Hailey Dunn, but all have been denied.
Colorado City is located about 70 miles west of Abilene and has a population of around 4,000.
Hailey, a student at Colorado City Middle School, was last seen on the afternoon of Dec. 27, when she reportedly told her mother's boyfriend, Shawn Adkins, that she was leaving to spend the night with a friend. Hailey never made it to her friend's house. Her mother, Billie Dunn, reported her missing the following morning, police said.
According to Abilene's KTXS News, the friend Hailey was to be staying with said she had not made any plans for Hailey to spend the night and was unaware she was coming over.
Colorado City Police, along with the Texas Rangers, the Mitchell County Sheriff's Office and other law enforcement departments in the region have conducted several searches for Hailey.
On Friday, a police bloodhound reportedly picked up Hailey's scent in the parking lot of a motel near the Dunn home. The scent led to the door of a ground-floor room, but the trail stopped there. A search of the motel's 24 rooms failed to produce any evidence in the case. A review of the motel's surveillance tapes also failed to produce any leads, the Abilene Reporter-News reported.
Meanwhile, Bivins said his department will continue to work toward getting an Amber Alert issued for Hailey.
"This community and, in particular, the family and friends of Hailey Dunn can be absolutely confident that we will continue to pursue the issuance of an Amber Alert with each additional piece of evidence we uncover until such a time as we meet the minimum standards established by the Amber Alert system in Texas," Bivins said.
