Mark Tildesley. He was abducted and murdered by a paedophile gang in 1984 and they were caught and jailed, however, they have never revealed where his body is buried, thereby preventing the family having real closure. So cruel. I remember the days after he went missing vividly, all the police helicopters out looking for him, and I think of him now and again in the hope his remains will be found so he can be given a proper funeral.
