Ms Neave allegedly made the threat during a visit in November 1994 by former family aid worker Bryony Smith. Ms Smith told Northampton Crown Court: 'Ruth was saying that Rikki's behaviour was very hard to cope with. She said that if someone didn't help her with him she would kill him.'
The jury heard that Ms Neave had begged social workers to take her son into care as early as April 1993. Rikki was put on Cambridgeshire CC's at-risk register but remained with her.
Under cross-examination by defence QC Nigel Rumfitt, Ms Smith admitted that if she had taken the threat seriously she would have ensured that the boy was taken away.
