It's a good question. A couple of days after the incident, a man with some inside knowledge, relayed to him by a person who was in the house the night of the fight, went to Karen Read's lawyers office and said Karen didn't kill him, there was a fight in the house and that is how he died. Ever since that time it has been a rock fight for Read's team to get any data from the state. For example, they still have not tested DNA on O'Keefe's clothing. It is in a California lab. This is a critical piece of evidence that could exonerate her.
If you look at the autopsy photo, the wounds on O'Keefe's left arm appear to be from a dog, The state says no, it is from when his arm dragged on the ground after he was hit. As Brett says with the whole thing stinking, the home owner had a German Sheppard that was trained and was in the home the night of the fight. If there was a fight, that dog was attacking the non-family member. After having the dog for years, the home owner suddenly got rid of the dog with no info forth-coming on where the dog went. The home owner was never asked about any of this. They were never questioned as suspects at all.
Turtleboy brought light to all of this. You almost need to take the time to read it and understand it because there are many layers to it.
