The forensic team that produced these results seems like less of an objective 3rd party and more of a laboratory that tries to use "science" to help their customers reach a certain conclusion. If you watch as much murder porn as I do (Dateline, etc) you'll know that it's not that hard to find experts that can come to a completely opposite conclusion from the prosecution.
That alone doesn't invalidate their assertions but you should know they're most definitely starting with massive fraud as the conclusion and working backwards to support that conclusion. For one, referring to missing paperwork, paperwork that most counties probably don't keep very long, as evidence of fraud.
