DECATURVILLE, Tenn. — After prosecutors revoked an immunity agreement, a third man could face charges in the disappearance of 20-year-old nursing student Holly Bobo from her home near Parsons three years ago.
According to documents posted online by The Jackson Sun, a March 6 agreement granted Shayne Austin immunity from various charges, including those arising out of the disposal of Bobo's body.
In return, the 29-year-old agreed to assist the investigation, including "accompanying law enforcement to any location requested."
Prosecutor Beth Boswell later revoked the agreement, saying Austin had not been truthful with investigators.
Austin claims he was truthful and is suing for breach of contract.
Investigators have not recovered Bobo's body.
Two people have been charged with murder and kidnapping in the case, and investigators say there could be more charges forthcoming.
