In the 1980s, he was imprisoned for abducting and molesting a 14-year-old girl.Additionally, when police dug up his backyard while looking for evidence in the Shannon Melendi case, they were shocked to discover articles of women's clothing that were smaller than his wife's. This led them to conclude that Hinton was involved in many more violent cases against women.Hinton's chilling confession about Shannon's murder further proved that he was a very dangerous s*xual predator who deserved to be behind bars for life.
