fwiw, no where in the autopsy report does it state that tape was "wrapped around" the face, mouth and nose. It actually states that tape was attached to the hair and overlying the mandible and maxilla, per Dr Utz (the first ME to examine the remains). Dr Shultz states that it can be INFERRED that the tape was what could have held the mandible in place. However, it is also noted that plant growth had permeated the remains. IMO, this too could have held the mandible. And that is exactly what CSI Hanson, Dr. Shultz and Dr. Utz testified to in court. No expert testified that the duct tape was responsible for holding the mandible in place during the decompositional process in court. Also, IMO, the muck could have been responsible for the position of the skull and mandible. I don't see how the duct tape could have held the mandible. The skin, hair and duct tape would have loosened before the jaw muscles decomposed. The PT theory the tape was applied to the skin, then skin loosened and fell off the face but somehow the tape held enough to keep the mandible in anatomical postion? IMO, I just can't buy it. Again, all JMOO.
ETA: As to Dr. Spitz, his theory was just a smokescreen put on by the defense.
