Do you think he removed his parka and hid it and was guarding it until he felt it was safe to run home unseen?
Absolutely. He was acting strange (LF, RW, DH, MO & CH all said how suspicious looking LM looked when he was on the NB road) because he knew that khaki jacket had some blood on it which would have been noticeable had anyone gotten up close and personal with him (and hence why he probably hid it after the F&W sighting). What's strange, however, is the contrasting eyewitness accounts of what he was wearing in his upper body between 1800 -1810. The 3 pushbike boys, MO & DH and CH all gave different accounts of clothing. The 3 boys -- well, AH did (will be interesting to read the transcripts of the other 2 pushbike boys) -- said he was wearing a khaki green shirt that went past his waist; MO & DH said he was wearing a green bomber jacket (though, their testimonies have yet to be uploaded); and CH said it was a khaki green parka jacket that went to his thigh. As I said, most of the testimonies from the aforementioned have yet to be published, but I think that 4 of the 6 identified LM in court as the person they'd seen that day -- and, crucially, they never saw anyone else on that stretch of road. Not a single, solitary soul -- and not someone who was LM's twin.
Apologies again for any typos, etc ... but I'm back in a hotel in Bristol as I have a conference on Wednesday and I'm having a a few beers from the minibar and typing from my trusty Samsung phone. It's been a hectic day and I'm exhausted!
