As i said...not much to add, but i did want to comment about the blue car. I thought at the time of his accident that it was very strange and it has been hovering in my brain ever since. Is that car blue? to me it looks blue. Maybe it is an older model. I think there was a dark blue 2010 model.
It was on loan from a friend. I thought at the time it would have to be a GOOD friend, or family member, given the circumstances, the community gossip (reflected in his sister's defensive comments) and GPS's initial reaction to the call. Not many people would want to be involved.
Now we hear that a blue car may be involved on the actual night of the murder, so i'm more curious than ever to find out the identity of the friend. It may well be that that person is the main perpetrator.
