Not everyone wants to talk to us journalists when we contact them out of the blue. Tabitha Opp was an exception. Opp, 38, was eager to chat because she wants people to hear the story of her brother Shawn’s 2020 disappearance. She and her family have been desperate for tips, for leads, for any information that could help them understand what happened to Shawn, who was last seen walking away from his mother’s house in Riverside.
