JY is guilty of being a lousy husband, a cheating husband, and displaying very inappropriate behavior. He very possibly may be guilty of this murder or involved in it, However, the PT still has not proved beyond a reasonable doubt that JY is guilty. As Wolfpack has indicated, we are left with too many assumptions of certain coincidences to conclude he is Guilty.
Nothing at the hotel leads me to be convinced he actually left the premise that night. I threw out Gracie's testimony so I have no eyewitness putting him out of the Hotel. There are unknown fingerprints at the crime scene, and jewelry taken at the crime scene. The size 10 shoe print has not been conclusively resolved as to source. The HP sole prints could have been made by a similar shoe or by his shoes if the shoes were in the closet and not at Goodwill. There is no evidence that medicine was given to CY. I threw out CB's evidence as well, but FH's testimony seems solid. CY failed to mention her dad's name when re-enacting the murder with the dolls. JY had no identifiable injuries to his body. It appears someone cleaned CY and there were no fiber transfers or blood between hotel and the home.
All of these are MOO.
