Well for starters ... the cement/tape that was in his storage facility matched the tape that was on Laci. He sold her car within days of her missing, he tried to sell the house, he kept in contact with his girlfriend after Laci's disappearance never once telling her that his wife was missing and never once expressing sadness that she, 8 months pg, with his son couldn't be found, he referred to her and Conner in past tense. He used Conner's room for storage right after their dead bodies washed up on the shore after stating that he couldn't even bare to go into his room. Not to mention that he was being tailed by the cops so he took them on a 3 1/2 hour tour of nearby cities trying to lose them before the pulled him over and arrested him with a new look, dyed hair and his brothers id and a whole lot of money on him.
He killed his 8 month pg wife in a cold heartless way and has still yet to show remorse for it. I hope that bastards rots in hell.
