A main character on Sheriff Country appeared to leave the show - but is this a permanent cast exit? During the Friday, April 17, episode of the hit CBS series, Cassidy (Michele Weaver) was finally able to solve her missing sister's case. That involved Cassidy getting kidnapped by a serial killer who got away with murdering women for years. While Mickey (Morena Baccarin) saved Cassidy just in time, the deputy asked for some time off. The final scene showed Cassidy and her mother driving off in her car while healing from their loss.
