A second man was arrested Friday and charged with concealing the death of south Georgia teacher Tara Grinstead, according to arrest warrants.

Bo Dukes, 32, allegedly helped Ryan Alexander Duke "conceal and destroy" Grinstead's body in October 2005. Dukes is not related to Duke, who has been charged with Grinstead's murder. But the two were classmates at Irwin County High School, where Grinstead taught history.

On Oct. 23, 2005, Grinstead was killed in her Ocilla home, according to the Georgia Bureau of Investigation. Then, Dukes and Duke allegedly took Grinstead’s body to a pecan farm in neighboring Ben Hill County some time during the next five days, according to arrest warrants.

Dozens of Georgia Bureau of Investigation agents searched a pecan farm in a south Georgia town for Tara Grinstead’s remains Tuesday.

The GBI secured warrants Thursday against Dukes, who surrendered Friday at the Ben Hill County jail. He was charged with concealing a death, hindering apprehension and tampering with evidence. Dukes waived his first appearance, posted $15,000 bond and was released from jail shortly at 12:30 p.m.

Last week, Duke, 33, was arrested and charged with murder. The GBI declined to say how Grinstead died, but arrest warrants accuse Duke of burglary and aggravated assault, stating that he “used his hands in an offensive manner” and harmed Grinstead. Duke then allegedly removed Grinstead’s body from her home, according to a warrant charging him with concealing a death.

Details on a possible motive have not been released.
