In March 1997, Willa Jean Ferrier, Crystal Conaster, and Chris Boswell all spent the night at Willa Jean's after a fun night out. The next day, they were all found dead. Roscoe Garland testified that the murders were committed by his father, John Roscoe Garland, but dad blamed them all on his son. John Garland was ultimately convicted of the 3 murders based on circumstantial evidence, but the family, and the public remain divided. It's a case of "who done it?" and of Dad Vs. Son.
