In 1985, two twenty-seven-year-old friends left their suburban Detroit homes for a hunting trip in rural Michigan. When they did not return, their families and police suspected foul play. For eighteen years, no one could prove a thing. Then, a relentless investigator got a witness to talk, and a horrifying story emerged. In 2003, this bizarre case hit the glare of the criminal justice system, as prosecutors charged two brothers, Raymond and Donald Duvall, with murder. With no bodies ever found, the case hinged on the testimony of one terrified witness who saw a bloody scene unfold—and who was still nearly too frightened to talk. Now, the truth behind an eighteen-year-old mystery is revealed against the backdrop of an unusual, electrifyingly dramatic trial. Raymond and Donald Duvall bragged to friends that they killed their victims, chopped up their bodies, and fed them to pigs. A Michigan jury soon had evidence of this brutally methodical execution—evidence that would lead a shocked courtroom through the heart of evil and beyond a shadow of a doubt.
