And what about Dr Craig,he should have known roughly how long Sheila had been dead.There are a number of easy ways to tell by the different stages of livor mortis.His statement seems more concerned with the upheaval in the kitchen and what type of rifle was lying on Sheila.I cant believe that he didnt make some sort of educated guess at times of death.Wouldn't the police have asked him for a rough idea? One look at Sheilas skin and a prod about at it would have been enough.Craig must have known how much lividity was present on each victim.Where are his notes? He was the first physician to see the bodies,his information should have been invaluable.Did he give any evidence at Trial?
