I've been looking again at Dr Lyall's evidence (
as reported by Hull Live from the Wednesday recap) & several details stuck out for me. I've put the key injuries in bold & the 'opinions' in italics.
He said that there was ingrained dirt and silt on the back of each hand and the lower part of the torso, the neck and upper parts of the chest was ingrained and he said this is just the sort of feature you may encounter on a body that has been exposed to this sort of material at the time
[...]
He went through the list quite quickly. He recorded in the upper side of the head an area of grazing. No injuries to the back of the skull to the left side of the face there were lots of small areas of grazes similar to what are seen on bodies removed from water.
"Abrasion on the forehead, the nose and the eyelids all consistent with movement of the body in water and he thought all probably happened after death.
"Superficial skin on the ears had been removed in places which could be the result of grazing in the water. Other abrasions all consistent with post-mortem passage of the body in water.
It seems to me he's deliberately being cautious here, never saying that these abrasions
must be caused by the body being bashed around in the river, only that they
may be. That leaves open the possibility of them being caused by something else - let's say PR dragging the body across frozen ground & pushing it into the water...
Hopefully the jury will pick up on that possibility.
Right, I'm done for tonight. Thanks to
@jamjim for the updates again today, & fingers crossed for a positive development on Thursday, even if it's only giving the jury the go-ahead for a majority verdict.
