COLORADO CITY, Texas — Shawn Adkins was arrested for murder by the Big Spring Police Department on Monday, according to booking information.

A private investigator confirmed to that the arrest was for the murder of Hailey Dunn.

Hailey was reported missing in December 2010, and her remains were found near Lake J.B. Thomas in Scurry County in 2013.

Adkins was dating Hailey’s mother, Billie Dunn, at the time of her disappearance. She said this news does not come as a shock.

“I’m not surprised, and I thank God that person has been apprehended and is going to pay for what he did here on earth,” Billie said.

Hailey’s father, Clinton Dunn, was also relieved after years of unanswered questions regarding his daughters disappearance.

“I instantly called Hailey’s father Clint and told him what I had been told and he said ‘I had a feeling today would be the day,'” said Erica Morse, a private investigator for Clinton.

They know this process still has a ways to go but are grateful Adkins is behind bars for the time being.

“We do know of some evidence that would be a key element to solving this case,” said Morse, “and now Shawn Adkins is behind bars, so there you go.”

As of Monday afternoon, Adkins was in the Howard County Jail on a $2 million bond.
