I'm not totally convinced of his guilt.
-One of the things that stood out for me was how upset he was by the second hung jury. Had he been guilty, I would think he would be very relieved by a hung jury, not anguished.
-The fact that they were trying to have their son join them on their hike made me think this wasn't premeditated.
-They were REALLY reaching with the secretary's testimony and trying to spin her into being a mistress when she plainly said she didn't find him inappropriate and he never said anything sexual. Just sounded to me like her own husband has a jealousy issue.
-He remarried over a year (almost 2) after his wife's death. Don't forget, this was a family friend, so the getting-to-know-you is abbreviated.
-His wife's own parents support him. I usually weigh that heavily because when something like this happens I think the family of the victim will always scrutinize the closest and be the hardest to convince of your innocence.
