About
Kun's testing of two later-submitted clothing swabs found no canine DNA in K9 qPCR or dog-focused meat-ID testing, while detecting pig DNA; the prosecution used that result as counterevidence to an animal attack, not as a dispositive finding about event mechanics. Kun tested only the swabs she received and did not collect them or know the source collection process. She said the nuclear result could reflect degradation, inhibition, or no canine nuclear DNA, although the mitochondrial meat-ID control showed no inhibition. In Trial 2, Russell identified no actual process step that went wrong, explaining her concerns through the delay in swabbing and unknown transport and custody.
