I found the report on docstoc, thanks.
He examines the roots on pictures provided to him by the Medical examiners office. He is guessing the diameter and then following up with a statement of 3 to 6 months. Just a guess imo
No NTS that is incorrect. Dr. David Hall responded to the remains site on December 11, 2008 and saw first hand the root growth on the remains. (pg.9/3472 of the remains site processing document).
Referring back to the topic of the child calling for help at the school, again, I think it was only in the docs to show the water level of the remains site at that timeframe.
