Robert Thompson and Jon Venables

Robert Thompson and Jon Venables are two felons, known in British history as the youngest convicted criminals at the age of 10. They were responsible not only for truanting from school (in the process), but mainly, for kidnapping and killing two-year-old James Bulger. They abused him on the way, and left him to die on railroad tracks. They were kept in custody until the age of 18, and one of them is in jail again.
