Scott is a murderer. He murdered his pregnant wife and his pre-born son who they had named Conner. Scott told the woman he was cheating on his wife with that the coming Christmas would be his first Christmas without his deceased wife. That was before Laci was murdered.
There was a lot of circumstantial evidence such as where Laci and Conner's bodies washed up, amazingly just where they would have washed up if someone tossed Laci off a boat right where Scott was fishing

, such as Scott telling different stories about how he spent his day, Scott not telling his wife about his boat, Scott washing the floor and saying the cleaning lady did it, Scott ordering a porn station the night after Laci went missing, Scott calling Laci's parents and saying that she was missing rather than starting the conversation with "Is Laci there?" Scott telling Amber (girlfriend) his wife was dead while she was still alive, Scott dying his hair having 10's of thousands of dollars in cash and his brothers ID when he was picked up, Scott stated that he was leaving Conners room in tact because he fully expected Laci and Conner to return one day but the truth of the matter was Scott was using Conner's nursery as a storage room, and much more which I am too tired to remember.
I read two or three books.
Scott's parents were enablers who helped create a monster.
Scott IMO is a true psychopath, I believe it was after he was dating Amber that he and Laci were driving and Scott had a big old cat who ate the canary smile on his face, Laci asked him why he was smiling and he said "Because I love you so much." Laci was so impressed she told her mom or someone else that she felt like the luckiest woman in the world.
Oh and the boat, it was a small shitty boat and Scott told no one about it yet he said he had taken Laci out on it (and supposedly she didn't tell anyone). The problem was that Laci suffered from terrible seasickness and was afraid of the water. She never would have gone on a rickshit boat on the ocean and not told the entire world about it because by all accounts Laci never shut up.
Anyhow I have an opinion on the case. Scott is a dirty filthy murdering psychopath who should be put to death sooner rather than later.
