COLORADO CITY, Texas -

Billie Dunn, the mother of missing teenager Hailey Dunn, was sentenced Wednesday to one year probation, and she has moved ? about 250 miles away from Colorado City.

Billie Dunn appeared in a Mitchell County courtroom and was sentenced to a year?s probation stemming from her arrest on March 17.

Billie Dunn pleaded no contest Wednesday to a charge of making a false report to authorities and was initially sentenced to 90 days in jail. However, the sentence was probated to one year as part of a plea agreement.

Other charges against her ? lying to police, hindering an investigation and drug-related charges ? were dropped as part of the agreement.

Billie Dunn was arrested and charged on March 17 after she lied to authorities concerning the whereabouts of Shawn Adkins ? her former live-in boyfriend who remains the only named suspect in the disappearance of her daughter, Hailey Dunn.

Adkins, on March 17, was inside Billie Dunn?s home ? when she lied to officers at her door who were seeking to issue a search warrant to Adkins.

On Wednesday, KTXS News was in Colorado City and discovered that Billie Dunn?s home in Colorado City is now padlocked.

Mitchell County Sheriff Patrick Toombs confirmed that Billie Dunn has moved to Travis County in the Austin area. Court officials said her probation is to be served in Travis County, where she now lives.

Hailey Dunn disappeared from her family?s home on Dec. 27, and Adkins was the last person who claimed to have seen her that day.

Adkins said he returned to the Billie Dunn home in Colorado City and that Hailey said she was going to her father?s house nearby and then to a friend?s house to stay the night.

Hailey Dunn, a 13-year-old eighth-grader at Colorado Middle School, never arrived at either place. The friend later told authorities that there had been no plans for Hailey to come over that night.

The next day, Dec. 28, Billie Dunn reported her daughter missing.

Multiple law enforcement agencies, including the FBI, joined forces in the widespread search for Hailey.

The case also received widespread media attention, including national exposure through several episodes on the ?Nancy Grace? cable television show.

Over the ensuing weeks and months, hundreds of people turned out to search for Hailey, including national search organizations.

On March 30, authorities admitted that they believe that Hailey Dunn is dead and that they were focusing their efforts on finding her remains.

Back in early January, Adkins and Billie Dunn both failed polygraph tests administered by law enforcement officers seeking information about Hailey?s disappearance.

Since then, according to law enforcement affidavits, authorities have found thousands of pornographic images, including some child pornography, on devices used by Adkins.

No arrests have been made concerning those findings.
