First off, thank you for being cordial and civil and not attacking me for having a different opinion. I appreciate that!!
I don't want to see ANYONE get away with this crime. I want whomever did this to Laci to spend the rest of their life in prison. Period. I just don't think it is Scott. It has also come to light that the actual investigation into what happened to Laci, specifically Scott, was not conducted properly with evidence being overlooked. I completely agree with you that there were behaviours and actions of his that would make anyone suspect him. But key word being there suspect him which is different than him actually being the killer. Let me just respond to a couple of your points:
Affairs are often motives for murder - Yes, they absolutely can be but in my opinion, with affairs unfortunately being such a common thing, to me it doesn't tell me anything. He had an affair, he's a liar and a cheat for sure, but a murderer? I am not convinced
Sharon Rocha didn't know about the affair when she sang his praises - You are absolutely right, she did not know about the affair at the time she gave those statements and press conference. But, as soon as the affair came out, she and the rest of Laci's family completely turned on Scott. And, I can understand why. Here it is, their daughter and her unborn child are missing and on top of that unimaginable stress and despair, they find out that their son-in-law was cheating on their daughter. With everything else they were dealing it, I can see how that would be enough for them to say he is guilty. The palpable anger they must have felt finding that out on top of their sadness.
I also fully agree with you that it appears he was intending to flee. But, if I was the prime suspect in a murder that I absolutely knew I was not guilty of and the police were honing in on me, it may be enough for me to be paranoid and scared and anxious and for me to want to get the hell out of there. I know it would be easy to say "well if someone isn't guilty than why are they fleeing?" but look at it from the perspective of, holy F, I didn't do this and I am terrified. I want to just run away.
