The husband of a woman missing since June was arrested on suspicion of murder after her body was found buried deep in a gold mine he operated, police said Sunday.

The body of Cynthia Hankins, 36, was found Saturday under tons of dirt in the mine, 33 miles north of Craig.

Terry Hankins, 70, was arrested on charges of first-degree murder, abusing a corpse, tampering with evidence, forgery, theft and possession of a controlled substance. Mrs. Hankins was reported missing June 3.

The suspect was in custody at the Moffat County Jail. Mrs. Hankins was likely killed in the city before she was buried, police said.

"Utilizing heavy equipment and hand tools, it took investigators over six hours to exhume the burial site," police said in a written statement. The body was found in a grave about five feet deep and covered with a pile of dirt about 12 feet wide and six feet wide.

Police said detectives were investigating other criminal activity that allegedly involved Mr. Hankins when they uncovered information related to his wife's disappearance.

Search warrants containing details of the investigations were sealed.
