Police say a Texas woman whose 13-year-old daughter is missing lied about the whereabouts of her boyfriend, who was previously named a person of interest in Hailey Darlene Dunn's disappearance.

Billie Jean Dunn was in court in Colorado City Friday on charges of misdemeanor hindering prosecution, possession of a dangerous drug and giving a false report to an officer.

Officers arrested Dunn Thursday night when officers found Shawn Adkins at her home after she denied he was there.

Dunn reported Hailey as missing Dec 28.

Mitchell County Sheriff Patrick Toombs says officers did not arrest Adkins and declined to explain why they were looking for him.

Dunn is being held on $6,500 bond and has declined to have an attorney appointed.

Both Adkins and Billie Dunn have denied having any involvement in the girl's disappearance. Adkins has no listed telephone number, but he previously told The Associated Press that he would "never ever do anything to harm Hailey."

Hailey's disappearance brought anguish to Colorado City, a town of 4,500 people about 240 miles west of Dallas. More than 100 billboards featuring her picture, information about the case and a law enforcement phone number have been set up along interstates in West Texas and other states. Investigators and volunteers conducted extensive searches in surrounding fields and landfills.

Volunteers trekked through fields covered with shrubs and small trees, searching landfills and retracing steps already taken by police. Candlelight vigils have been held and fliers with Hailey's photo have been taped across the city.

Friends and family told investigators it was out of character for Hailey to leave for an extended time without checking in with her mother. If she had planned to stay overnight at a friend's house, Hailey left without her toothbrush, hairbrush and contact lens solution. Cash, a new iPod, and a jacket that friends said she would not leave home without were still in her room.

The girl is described as white, standing 5-foot-1, weighing 120 pounds, with hazel eyes and brown hair with blondish streaks. There is a $15,000 reward for information leading to the teen.
