..yes and they are damning to Jeremy Bamber.
I disagree, having looked at them in detail. In order for the prosecution case to work, Jeremy must have gone to and from the scene using a quick method, such as a bicycle or car. We can rule out a car. The bicycle method is just about possible but fraught with risk and danger that diminishes its plausibility.
By the way, given your posts on this particular topic, can we assume you are therefore discounting Caroline's theory fully? We already have the evidence of Len Foakes, which blows Caroline's theory out of the water and leaves us only with the sinking hulk: the suggestion that Jeremy committed the murders much earlier than believed. I assume you accept it can't be the case that Jeremy was cycling out to the farmhouse at 10 or thereabouts in the evening?
