Good question -
Based on docs used for search warrant; I'd expect forensic results on these to be presented at trial.
Seems to me these are supportive proofs ...
A family member stated prior to the gag order that they were told by LE that they have DNA.
Hope that they weren't referring to the cat.
Which document stated that there was a match to RA's cat? I don't believe that has been stated...only speculated. It's not in the PCA and the only other available doc relates to RL.
