Leading Suspect (not convicted) taken from Wikipedia.

James Martin Sr., a new resident in the area and a known child molester, offered his testimony as an expert into the criminal mind. With the exception of John Mark Byers, he currently has the largest file (57 pages) at www.wm3.org and has often been thought to be the leading suspect, especially early on in the case. Why he was removed from the suspect list eludes many people. In addition to failing the polygraph test, he also described the crime in great detail, with much information that had not been released to the public at the time of his interview (including the fact that the boys had been tied with their own shoelaces). He presented obvious signs of Antisocial Personality Disorder, and had at one time been hospitalized and incarcerated for sexually assaulting both his stepson and stepdaughter. He currently lives in Gatlinburg, Tennessee.
