Darrell Gene Devier lived in Adairsville, Georgia. He was responsible for the murder of Lisa Dawn Porter, a 12-year-old-girl. He was voluntarily interogaited by Holden Ford, who used the techniqiues from his past interviews to get a confession from Devier. He was later sentenced to death for his crimes. Wendy Carr flew to Georgia, hoping to prevent that due to bad publicity for their project, but was unsuccesful. Devier was likely exectued.
