Sounds more like an Uncle Bobby theory...
I love it, Jeremy murders five people including two small children out of pure greed, and you save your mocking scorn for Robert Boutflour.
Okay the guitar string suggestion is a bit out there, I quite agree, but nevertheless the ability to covertly gain access and egress to the house was proven, admitted and accepted unchallenged by the defence. I don't really see how JB can come back from that and try to contest the notion some 30 odd years later.

One wonders why the notion wasn't originally challenged. There's no logic in it but why does that matter.
