The families of two murdered schoolboys say their decades-long wait for justice has been "endless torture".
John Greenwood and Gary Miller were beaten at an old colliery site and found with severe head injuries beneath a mattress. The 11-year-olds later died from their injuries, their murders prompting fear and revulsion.
The tragic attacks also sparked high-profile appeals and, in recent years, a police apology. Their families remain hopeful they will one day see justice, however.
