As i said PC Ryan Galloway testified that his dog alerted but no forensic evidence of any human remains were presented before the court.
In my opinion the three quotes taken from reports on the trial illustrate the way in which
all the evidence presented knits together into evidence which was enough to secure the conviction for murder of both accused.
Dogs don't go along and bark and that's it ~ job done. I think it is incredible that there is any danger of that opinion becoming an accepted supposition.
The evidential clincher as far as I am concerned was the painstaking police search of the house which unearthed the evidence that the perpetrators were in London in the hotel at the time that letters had been posted purporting to be from Margaret but which her teacher attested could not have been written or dictated to another by her.
All the strands collected by the police and put together by the prosecution are what makes for a safe conviction. In my opinion there is no room for stand alone evidence and it is not in line with our system of justice that we ever know what evidence carries weight with a jury.
