There was a complete lack of canine DNA on the 4 tiny swabs taken from unknown locations of his clothing. The swabs were not identified as to wear on his clothing they were taken from. They could have come from the opposite side of his shirt. They could have come from the underside of his shirt. The fact is we don't know and that is another major failure in the investigation right there. How convenient.
The locations are not unknown and were put into evidence in the witnesses report and testimony.
I went to the trouble to post this evidence previously. It's in the testimony from Maureen Hartnett. She double swabbed each of the tagged locations on the arm of the sweatshirt.
She was cross examined on this by AJ in trial 1.
MOO.
