For twenty years journalist Larrison Campbell has been haunted by the murder of her grandmother in her Mississippi home. Known affectionately as “Presh,” the victim was found bludgeoned in her parlor, a towel over her face, and her purse dumped out. Despite a full-scale investigation, the case soon went cold.

Campbell returned to her hometown to re-investigate the 2003 murder. While it could have been a simple robbery-gone-wrong, police believed Presh knew her killer. For years, the family has suspected Richard - an oddball cousin who viciously quarreled with Presh over money days before her death - but has never been arrested.

In season four of Campside Media’s “Witnessed: Devil in the Ditch,” Campbell explores her story of loss and the unsubstantiated suspicions of the family black sheep. The host mines the social and political impact of a small Southern town society murder and asks if not Richard, then who?
