I'm starting to get confused!
He sold his car before the crime? Wasn't that their only car? So no car at the time of the murder?
And he wanted to sell the house? Was he in financial trouble? That can be a huge trigger for men who kill their families, in addition to the trigger of the wife wanting to leave the marriage.
They found pools of dried blood? What a doofus. Of course, LE could find blood even if he attempted to clean it, but to leave pools of it while a baby is scooting around the house and while wanting to sell the place is lazy and idiotic.
Would like clarification on the car - what was going on with that?
