Police investigating a grave robbery have received letters from people claiming they know where the body is and are willing to hand it back.
The remains of Gladys Hammond, aged 82, were taken from the grounds of St Peter's Church in Yoxall, Staffordshire, under cover of darkness in October last year.
Detectives on BBC1' s Crimewatch programme said they had received letters from people who had "intimate knowledge of the crime".
The desecration is thought to have been the work of animal rights extremists opposed to a guinea pig breeding farm which is co-owned by the deceased's son-in-law.
Detective Chief Inspector Nick Baker said: "The author claims to know the whereabouts of Gladys's body and shows a willingness to return it to the family." DCI Baker appealed for the author to get in touch, saying the letter contained a code word which would identify them.
