I just watched 48 hrs on this case and believe the jury got it right. If someone else had done it, there should have been blood as a murderer from the outside would not have cleaned up.
And when was she giving him a backrub to account for the DNA under her nails, he was with his mistress all day?
Also he may have strangled her last before throwing her into the pool, they may have grappled a little at first when he first attacked her, enough for her to scratch him.
It just is not reasonable to think that someone else came into their backyard and took a chance that a woman sitting out there was going to be alone long enough to kill her-also she was shown not to have been wearing her jewelry that day so why would she pile on $40K worth of jewelry to go swimming? That made no sense at all, not to mention a passing robber would harldy expect a woman at a pool to be a good target for a worthy take.
No one else had a motive to want her dead. I feel sorry for his kids and think his sister and mother are in serious denial. They go on and on about how they know him so well, but don't really want to talk about his affair; obvoiusly they did not know him that well.
In most cases...the obvious suspect is the right one. We are seeking reasonable doubt in our courts, not absolute without a doubt , doubt. If it is more likely than not and the scenario presented fits with the facts...well you have to vote guilty.
If he had not been having an affair (motive) than I would listen a little closer to his protestations of innocence...but that with the other stuff adds up for me.
