Wow, this highly respected ME (ID'd Chandra Levy and worked on the DC Sniper Case) is doubtful this is Hannah bc he says it takes 6-9 months to achieve such skeletized remains under such weather conditions...rewinding and rewatching.
So, either, JM used a decomp accelerant of some sort, this is not Hannah, or this ME is off base.
Hmmm.... Will be interesting to see what the dental records and DNA reveal about these remains. There are other missing women in this area. I still bet my money on Hannah, but anything is possible, it has happened before (remains presumed to be the person searched for and turn out not to be). For Hannah's family, I hope this will be her to provide some semblance of closure for them.
