• Further forensic tests were carried out for the prosecution by forensic scientist Roy Green in November 1999. (The results actually came back while the trial was going on.) These tests were on a pillowcase from the deceased's bed. Obviously the prosecution were hoping this would provide further proof against John.
  
  
• The area tested was a faint bloodstain which could have been from Mrs. Bolshaw, who had a small cut on a knuckle. (Covered by a sticking plaster when seen in the bath.)
  
  
• The result showed the presence of DNA from at least two individuals, one of who could have been Mrs. Bolshaw. The other contributor was not John and appears to be female.
  
  
• No real explanation could be offered as to how this other person’s DNA got there. Someone coughing or sneezing near the bed or touching the pillow could have caused it.
  
  
• Roy Green said it could have happened before the attack, at the same time of the attack, or afterwards.

• As someone else’s DNA was mixed with that of the deceased, on a pillowcase from the bed she was apparently killed on, it has to raise further doubts as to who killed her.

Whose DNA is it and why should it be assumed that, if it did belong to a woman, she was not implicated in the murder in some way?
