You can not possibly believe what you have just written? It does not matter that other people have handled the rifle and moderator?
You have to realise that contamination in that way actually could have removed the absolute proof that Jeremy was the killer?
Members of the same family with the same DNA as June handled the moderator?
The evidence about the blood was misrepresented by the judge?
There has already been threads on the relatives expertly contaminating the silencer.
Supporters are just repeating the same arguments. Or claiming the police are withholding documents.
The relatives would have to -
Decide to frame.
Know the silencer was not used.
Know the rifle was too long for Sheila to use with the silencer on.
Know Sheila's blood type.
Know each others blood type.
Expertly put blood into the silencer creating the rifle back splatter effect.
Expertly put red paint onto the silencer.
Not wilt or retract over the next 30 years.
All within a short period.
