Gordon Boon was sentenced in 2001 to six years in prison for molesting three young girls. Detectives would not say when he was released from prison, The Daily Mail reported.

His body was discovered Monday near a turkey farm in Great Witchingham, Norfolk. Police were unsure if the killing took place there.

Boon was last seen in a Norwich pub Friday. His son reported him missing Saturday.

In 2001, Boon pleaded guilty to assaults between 1975 and 1982. In one case, he gave a young girl liquor and got her to play strip poker.

Detectives were reportedly questioning some of his victims.

In 2000, William Malcolm, 47, a convicted pedophile who had charges dropped the last time he went to trial, was shot in his London apartment. No one was charged with the killing, which set off a string of vigilante attacks on pedophiles.
