Re: Child's DNA on medicine dropper not meaning she was given medication that night - I agree, it doesn't.
Re: Unknown fingerprint on medicine bottle cap and/or upside down cup that comes on top of medicine bottle - I am unsure of upon which of these the unknown print was found. In either case, my question would be, where was the medication obtained? When was it obtained? How full was the bottle of medication? If obtained from a pharmacy shelf, it could have been from another customer or pharmacy worker handling the bottle. If obtained by JY as a sample, could have come from a person who works in the factory where produced or from a person who unpacks samples for salesmen.
So, to me, an unknown fingerprint on a medicine bottle means nothing. BUT the fact that this particular medication was found in the child's room points in the direction that CY was being given this medication at some point by someone. Could Daddy have given it to her? Of course he could have. And he knew one of the main side effects of this medication is "drowziness".
I surely hope the Prosecutors are prepared to deal with the "paradoxical hyperactivity" listed as a side effect and used by the Defense during Trial #1. A paradoxical side effect is unexpected and is not "usual". It is unusual. But if it happens often enough (and I don't know the percentage) during clinical trials of the drug, it must be listed. A PDR gives information about the number of subjects in the initial clinical trials and the number who experienced a listed side effect. It is not hard to find this informationl. But by and large, the side effect to be expected from this medication in the vast majority of administrations is drowziness, NOT hyperactivity.
Unknown fingerprint(s) on computer print out papers. These were print outs that were sitting in the print out tray of the printer, located in the office. I think it was the print outs of the purse information that he "wanted the sister to come and retrieve." NUMEROUS phone calls, including calling his mother to request that SHE call Meredith about picking up these printouts? Yeah, right.
To my knowledge, unknown fingerprints were NOT found on the papers found in the Master Bedroom along with Michelle's body. Explanation? In pre-planning this murder, Jason obtained computer paper in advance from some other place - perhaps at his work, then placed this paper into the home printer to be used on that particular evening.
Likely LE did not test it, but I wonder if any unknown prints appeared on any of the
unused paper sitting in the printer? That would be interesting to know.
IMO

This trial has gone much like the Scott Peterson trial. It is based on circumstantial evidence - as are many murder trials - and it will be up to the jury to make a decision on that evidence.
Way, way too many coincidences for me. There is no getting around it, the sleazeball JY was smart. He watched a lot of crime shows and he had a lot of luck. But I think he did it. And yes, he had 4 million motives.
