The eye witness testimony I'm not sure I put much faith in however, what hits home to me are the bizarre set of coincidences. By that I mean the camera issue at the hotel, the missing clothing, the clean up of the child,and the increase in life insurance. Add to that his seeming hatred toward Michelle, the infidelities and testimony of violence with a past fiancé and its IMO damning. In some ways, I'm reminded of the Jeffery macdonald case. The fact that there are a few pieces of evidence that do not implicate him doesn't override the overwhelming evidence that points to him.
eta: sorry, I'm a newbie. I was responding to a reply from Otto and forgot to include the quote.
I don't believe that the child was cleaned up. She was able to use the taps and wash her hands and face (daycare employee), she had the step stool at home so she could reach the taps, she talked about a wash cloth, her feet were cleaner - but not cleaned in the way an adult would clean them (not actually clean), there is no evidence that anyone was in the bathroom with her ... nothing suggests that she was cleaned. There were bloody prints from the bathroom to the master bedroom. Her bloody socks were on the floor in the bathroom and two child's mismatched shoes were in the master bedroom bed.
Theories about someone cleaning the child's feet include that she was carried through the office, through the bonus room, down the stairs, into the garage, out the back door of the garage and then her feet were washed in an outdoor hose in the middle of a November night. That's way to much of a stretch for me to believe. Another theory is that baby wipes were used, but none are in evidence. The child was toilet trained but wore a diaper at night, so she could have removed her own diaper. There was blood on her pyjamas.
I don't see any evidence that someone cleaned the child.
Is it really believeable that the guy walked around telling everyone - including the daycare employee - that his marriage was miserable and he was on the phone non-stop with his girlfriend (before and after the murder - other than when they were sleeping) and then he murdered his wife? That's a bit careless of him, but wait, at the same time he's very organized to stage shoe prints for someone with much smaller feet ... and he's completely unorganized in this pre-meditated murder and he doesn't have enough gas to make the trip.
Let's throw in the gas attendant ... the only gas station with someone that remembers Jason but, oh dear, there's no video surveillance ... but wait, she agrees with the police. When she is shown a picture of Jason, yep, that's the guy. She's asked if she saw a white vehicle ... yep, she sure did. As time went on, she added that he was wearing jeans and even managed to change his height from 5' to 6'. She was rehabilitated as time went on until she was the perfect eye witness until ... oops, she had a brain injury as a child that resulted in permanent memory difficulties. When questioned months before the trial, she couldn't remember anything about the customer but wait ... during trial, she remembered everything that police wanted her to say. It must be a very strange memory problem where everything is forgotten but suddenly, during trial, it's all crystal clear ... how did that happen?
