Just wanted to chime in here regarding the possible state of JBR's human remains.
This was a full post autopsy. Embalming a fully posted case will actually render better results of long term preservasion than the standard embalming routine.
With a full post, meaning that the brain has been removed together with the organs, the mortician will be working harder than usual to ensure that the body will be viewable without looking too odd and most importantly, without a tell-tale smell.
The fact that the organs are now in a seperate bag is a BIG plus. Cavity fluid is poured into the bag which is sealed up tight. The body is then embalmed; due to cuts that have been made on various artories and veins, the majority of the formaldahyde will be running into the abdomen cavity, (and needs to be siphined out quickly otherwise the fumes and smell can be overwhelming!)
Most morticians will also go ahead and bring up other vessels to embalm with such as the femorals in the legs as a precaution in order to ensure all over distribution. If they're smart, in a crime case like this, they may opt to "hit 'em hard!" with a high index of solution which can also help to preserve "evidence" so to speak.
I would refer you all to a child abuse murder case in White Bear, MN where the body of a murdered boy was brought up 20 years after his murder. The mortician, knowing that this day might come, had treated the body with everything he had in order to preserve as much of the tissue as possible.
The result was quite mummified...but the bruises and marks were just as readable and clear as they had been 20 years before when the mortician questioned the offical finding of the boy having died from the "flu".
In JBR's case, my concern would be the fact that they buried her in a wood casket as opposed to metal. Metals will hold up better than wood, thus protecting the remains a little longer. I only hope that a top of the line vault was used in conjunction with the burial.
This has been a very long way to say that yes, she may still be very much intact.
