Another suspect has been arrested in Tara Grinstead’s disappearance, just one week after suspected killer, Ryan Alexander Duke, was charged in the Ocilla teacher's 2005 murder.

Bo Dukes, 32, was arrested and charged with concealing death, hindering apprehension or punishment of a criminal, and tampering with evidence, according to the Ben Hill County Sheriff’s Office.

According to a search warrant, Dukes helped "conceal and destroy' Grinstead's body in 2005.

Dukes was released on $16,700 bond, less than two hours after his arrest.
