SHERMAN (AP) – Authorities say three bodies discovered behind a barn in North Texas may be family members who disappeared from their rural Fannin County home last week.

Fannin County sheriff’s deputies found the bodies outside Sherman Saturday while searching for 73-year-old Harold Harpst, 79-year-old Sue Harpst, and Sue’s daughter, 48-year-old Regina Taunton.

Officials sent the bodies to the Dallas County Medical Examiner’s office and said identities can’t be confirmed until the autopsy is complete.

Sheriff Donnie D. Foster says evidence inside the Harpst’s home near Leonard on Wednesday, turned their welfare call into a homicide investigation and led them to issue an arrest warrant for 52-year-old Thomas Lloyd Taunton.

He was arrested Thursday in Stonewall, La., after his truck broke down.

The investigation is ongoing. No further information was released.
