The body found in an abandoned well Saturday has been positively identified as Bonny Cooner of Canon, the GBI said Monday.

Cooner’s cause of death was strangulation with blunt head trauma, said Kris Sperry, Georgia’s chief medical examiner.

Her boyfriend, Brent James Shubert, was arrested early Sunday in Anderson, S.C. He is charged with malice murder, aggravated assault and concealing a death. He is awaiting extradition to Georgia and additional charges could be filed, the GBI said.

Cooner, 33, was reported missing Jan. 28 by a family member.

Information uncovered during the investigation led the GBI and Franklin County authorities to the secluded well on Casey Road in Canon. Cooner’s remains were recovered and transported to the GBI Crime Lab in Decatur for the autopsy.
