Scorpio that's not answering my question is it...Although they might sell stolen goods it does not prove they nicked them. They could well say that they found them dumped at the back of their house or in a field or had bought them at a knock down price from a stranger.....of which they would still be in trouble for receiving stolen property. A court can't prove they actually stole it.

If someone is in possession of stolen goods, can't reasonably account for how they got a hold of said goods, and has no alibi for when the robbery occurred they are going to have probles because they could very well be convicted of being the one who stole them. That is why they rat out who sold them goods and that sort of thing. Or why one would admit to being a fence if something they bought had been obtained in a murder.
This case was not like that though this case was a classic frame job that fell apart and the person doing the framing is obviously the real criminal.
How did he try to frame her?
Passive frame
1) he killed her last, killed her in the master bedroom instead of her own bed and left the gun on her and even put her hand on it.
Had he done this only then when the frame fell apart there would be nothing but a proposed motive that he was the true killer (and Julie's testimony which coudl have been avoided by not tlaking to her about his plan for so long)
Active Frame
2) call police saying Nevill had phoned him to say Sheila had the gun and had gone crazy
3) tell police on the scene that Sheila had fired all guns in the house and had gone shooting with him
4) stage the bullets and tell police he left the bullets exactly where they were found and claim he left the gun out (the exact location he left it changed with each interview) and had loaded it in front of Sheila so she would know how to load it. Also to say it had no scope or suppressor attached.
He did other things during the investigation itself that gave himself away like change his testimony from not using the gun the week prior to claiming he used it repeatedly the week prior after the last known user said it had been found and put away with the scope and suppressor attached. Changing claims to try to negate a problem is a sign of making things up.
But the above just speaks to his frame job. The active frame job sunk him because when police found out Sheila could not have killed herself that establishes she was framed and the active frame job revealed who it was that framed her while the passive frame job did not.
It is for this reason even the defense admitted if Sheila wasn't the killer then it was Jeremy.
Trying to pretend this is novel fails. There have been plenty of cases where people who framed others ended up being caught because the frame fell apart and left them holding the bag.
