EATONTON, Ga. (AP) — The Federal Bureau of Investigation is offering a $20,000 reward for information in the beheading of a central Georgia man and the feared abduction of his wife from their home on Lake Oconee.

Putnam County Sheriff Howard Sills tells The Telegraph (http://bit.ly/1g8ca5c) that his office might arrange for more reward money.

Law officers have used sonar to search under the water in the lake and they've also combed wooded areas near the shore in their continuing search for 87-year-old Shirley Dermond.

Her husband, 88-year-old Russell Dermond, was found decapitated May 6 at the couple's home in their exclusive gated community on the lake.
