An investigation is underway after the Bibb County sheriff was found dead this morning at sheriff's headquarters from an apparent gunshot wound.

Sheriff's investigators said they received the call shortly after 9 a.m. Hannah was found dead from a single gunshot wound to the head in the restroom that adjoins his office.

Sheriff's officials are not yet making any official statement on the cause of death, but said investigators from Clarke County are being brought in to help with the probe.

Bibb County District Attorney Michael Jackson said they are ordering an autopsy to determine the cause and manner of death. No foul play is suspected. He also requested the assistance of the State Bureau of Investigation, and agents did respond to the scene.

"I"m shocked and stunned,'' Jackson said. "I enjoyed working with the sheriff over the years. I'm praying for his family."

Hannah recently marked his 29th year with the sheriff's office. He joined the force when he was just 21 years old. He took over as sheriff in January 2003.

As is protocol, the Bibb County coroner will take over as the acting sheriff.
