And this is just completely FALSE!!! I suggest going back to Day 12 of the 1st trial and listen to the testimony of Teri Kun. She specifically states that she didn't know where on the shirt the DNA swabs were taken from.
This was taken from Court TV's summery and Day by Day recaps.
MA v. Karen Read: Killer or Cover-Up Murder Trial
" A forensic scientist with a specialty in animal DNA, says she tested two swabs from a shirt and found no canine DNA – on cross defense suggests there is no insight to the swabs given to her by the Massachusetts State Police, ie she does not know what part of the shirt the DNA came from."
