Lori is, above all, all about Lori. Alex was her henchman, brother, confidant and friend — she probably liked having him around. But once LE started sniffing around asking where the kids were Lori knew she was in trouble. Dead Alex? Problem solved. Lori and Chad knew if they blamed everything on Alex it would muddy the waters, dilute charges, give a jury reasonable doubt and in their minds get off Scot free.
As soon as it was better for Lori that Alex died, die he did. That’s an awfully big coincidence. Too big IMO when combined with two murdered kids, two dead husbands and a dead wife.
Science is fabulous, and forensic scientists find remarkable ways to use it to solve crimes. But it’s easier for me to imagine there’s an as of yet undetectable substance out there that can kill someone than all those people dying at such convenient times of natural causes. How do Lori/Chad know about it if scientists don’t? Heck if I know but if any civilian could find a way, it would be them.
MOO
