How about the hair in the pliers? Or the tools he used to make the anchors? Or the bodies used to establish time (in a generalized sense, not the TV fantasy of a to the minute pronouncement) of death?
Hair in pliers? - First of all they could not establish by DNA that it was her hair but even if it was, so what - She knew about the boat - She had been in the boat. A strand of her hair found in their boat was not evidence of a crime.
Anchors? - What anchors? The prosecution claimed he made anchors out of concrete to weigh down the body. This was pure speculation based on the fact that he had concrete in his garage and some concrete dust in the boat. But again they never produced any thing remotely resembling an anchor that they could tie to her death. I have some concrete in my garage - maybe I did it.
Again - I'm not saying he is innocent - he probably did it but I'd have like to have seen some physical evidence - an actual crime scene - some blood from the crime scene - a cause of death - something.
Ann was right about one thing - Geragos is a moron. There were enough holes in the prosecution's case that any half assed lawyer should have been able to raise some serious doubt.
