Teen cheerleader Hailey Dunn went missing in Texas in 2010. A decade later, police make murder arrest.

A longtime person of interest in the disappearance of a Texas 8th grader has now been charged with her murder, according to multiple reports.

Hailey Dunn, 13, was a student at Colorado City School Middle School in and her mother reported her missing on Dec. 28, 2010, according to the Texas Department of Public Safety.

She was described as an outgoing teen who was active in sports, band and was a cheerleader.

Dunn was last seen leaving her mother’s house going to a friend’s house, but she never arrived, according to the department. A massive manhunt for Dunn ensued and lasted for three years.

Sadly, on March 16, 2013, Dunn’s remains were found near Lake J.B. Thomas in Scurry County, according to the department. The lake is about 25 miles from Colorado City, Texas.

Shawn Adkins, Dunn’s mother’s boyfriend, was long considered a person of interest in connection to Dunn’s disappearance. On June 14, he was arrested on suspicion of Dunn’s murder, according to KCBD.

He was booked into jail in Howard County on the murder charge, according to sheriff’s office records. Bond was set at $2 million. Adkins was released from jail on June 14, though it was to another police agency.

Police have not released details on what led them to arrest Adkins more than a decade after Dunn went missing.

Dunn’s mom, Billie, was previously arrested in the case when police say she lied about Adkins’ whereabouts.
