You would also have to have access to a DNA lab that will sequence a sample all the way out and give you the results no matter what they are. I may be wrong but it seems to me the way the labs work now is that time is money and when you bring a sample in wanting to match it to an "animal' in the woods and the sample starts showing markers that are close to human it is going to get stamped with a label "contaminated by persons in the physical custody chain".
Hiflier, I think I understand the psychology behind what you are trying to do. You seem to be trying to present a specialized scientist with a very intriguing piece of puzzle that is, what you hope to be, right down their ally of expertise and hoping it will plant a seed of deep interest in trying to solve it. When they cannot solve it using the currently known animals we know of in the woods maybe they will be more open minded in what else there could be out there to explain the puzzle. You will have to eventually have to deal with them saying that people are also in the woods. You were there so that means there is the possibility that other people could have been there. Some may see that the probability that others were there is very slim, but there will be many that will not go past that because they just do not want to go there.
