Shirley and Virgil Best were beloved, hardworking members of their Riverview, Florida, community. For forty-five years, they built a life centered around their faith, their family, and their successful tropical fish farm, Quality Fins. They were finally looking forward to a well-earned retirement traveling the world together in their RV. But beneath the surface, the couple spent decades dealing with the constant crises of their oldest son, Robert Best. A convicted con artist who had once defrauded a blind woman out of nearly a million dollars, Robert was facing a new, deeply disturbing criminal trial set to begin on the morning of November 12, 2015. Hours before he was expected in court, Robert and his wife, Marisol Best, drove to his parents' home, supposedly to pray with them. Instead, they found Shirley and Virgil brutally shot to death. This week we cover the tragic murders of Shirley and Virgil Best, the bizarre web of manipulation surrounding their son, and the ultimate act of misguided loyalty that resulted in a double life sentence.
