On June 26, 2007, at 12:49 a.m., a guard patrolling Nashville's main layby truck stop on Interstate 24 stumbled upon a gruesome scene. He immediately called authorities, and Detective Sergeant Pat Postiglione arrived first at the scene. Making his way to the back of the truck stop, the detective did not miss the naked body of a young woman lying on the ground. The body was displayed with the legs spread wide, the soles pushed together. The arms were positioned upward, and the bullet hole on the woman's head quickly provided detectives with a likely cause of death. As his eyes took in the details of the scene, Postiglione quickly realized that the killer was no amateur...One that would repeat the same crime, over and over and over again....
