(FILES) A picture taken on November 5, 1985 shows Bernard Laroche, flanked by two French gendarmes, arriving at the Epinal court house, eastern France. A French judge decided on December 3, 2008 to reopen one of France's darkest murder mysteries, in the hope DNA tests can help find the killer of a four-year-old boy, 24 years ago, lawyers said. Gregory Villemin was found tied up and drowned in the Vologne river in a bleak area of the Vosges mountains in eastern France in October 1984. A second cousin of the child, Bernard Laroche, was charged with the killing, based on evidence given by a sister-in-law, but was released from custody after she withdrew her claims -- only to be shot dead by the boy's father in 1985.
