We visit Boston’s half-sister, Arthene, and hear about his childhood growing up surrounded by criminality.But questions are raised about the stories Boston and Arthene’s mother, Mary Sellers, would tell them and make us question – did she lie to Vince and Russell? Did Boston really kill Mary Lou or was this the warped story of a grandmother who used hurtful lies as a form of emotional control?Before leaving California, Stephen and Dan also meet the third member of the podcast team, US journalist Annie Di Grazia, who starts digging for fresh details on Mary Lou’s disappearance and Chris and Peta’s murders.
