It is a good report, but it doesn't actually rule-out anything the prior SA reports have said, just said he doesn't agree with some conclusions, but the report does not go so far as to say that the other expert's opinion is not possible. Also, this report talks about how there should have been an abundance of the little fly critter parts and larvae IF a body had decomposed in the trunk.....HE DOES NOT say that would be the case if a vehicle had been literally DETAILED by a family quite experienced in getting things clean..........
So it doesn't hurt the defense, but it doesn't hold anything to save ICA.....IMO,
P.S. - good find....I had missed the report.
