Motive imo relates to an adoption that went awry. It's necessary to have an understanding of adoption psychology, attachment disorders and adoption reunions.
Fact is at the start of Sheila Caffell's life she was effectively rejected numerous times, or at least felt a sense of abandonment, this is likely to have caused an attachment disorder. Her adoptive mother adopted her and then as a result of this decision suffered serious depression resulting in ECT and in-patient psychiatric care. This was in 1959 when Sheila Caffell was around 2 yoa. Only weeks before the murders Sheila Caffell was reunited with her birth mother.
The prosecution claim that Jeremy Bamber was motivated by hate and greed but there's absolutely no firm evidence for this at all.
Most understand hatred and greed; not many understand adoption psychology, attachment disorders and adoption reunions so of course its easy to blame Jeremy Bamber.
The fact that Bob Woffinden has looked into the case and arrived at the same conclusion as the establishment tells me nothing other than he might be incapable of divergent thinking! No offence to Bob Woffinden.
Surprisingly Andrew Hunter, a former right wing mp, has taken up Bamber's case and is due to release a book this year. An established crime writer is also due to release a book this year. I understand both believe him to be the victim of a MoJ. My feeling is that Bamber's case will become a global news story of epic proportion later this year and rightly so if he's innocent. He went to prison at the age of 24; earlier this month he was 53.
