I just can't figure out how you could fall down the stairs and get broken larynx cartilage (usually result of strangulation) and seven blows on the back of the head.

And all that blood--my God. And presence of red neurons, which show long period of de-oxygenated dying. And the blood being dried. And fact they owed all that money, and she was insured. And according to the book, he stole money from their friends--stole a female friend's atm card and stole a thousand dollars, years earlier in Germany. And he lied about war injuries--the documentary really tried to make him look good, but the blood at the scene, the way the body was, all the stuff left out of the documentary about the circumstances of the death, the fact the blood was dried when he made the 911 call--he seems a lot guiltier in the book, but even the documentary had a hard time explaining the scene that greeted the EMT's.

The woman who died in first stairway, mother of the two adopted girls--was a family friend and not his wife. She left him money, too. She also had head wounds when they dug her up and did an autopsy, all those years later.

I thought a couple of things with the kids in the movie were very disquieting--when the one son said h e used to bang their heads together as punishment--that is so abnormal for a parent to do that; kids' heads are fragile, you spend your life protecting them from head injury. did you notice that?
