My buddies and I talked about this occurance for quite some time, and came up with a couple "parallels" in the stories: it has only happened with bucks,(age, size didn't matter) and it has only happened near rut time, when the bucks are in a different state of mind.
I would tend to agree with that.
Let me tell you why I am often skeptical of the forensic ability of some hunters. A cousin of mine told me a story of a buck he had shot through the heart with a 12 gauge slug.
Now as far as the forensic abilities of some hunters I would assume they vary like any other abilities of hunters. Some are good and others aren't as good. But, I can assure you that you aren't the only hunter intelligent to distinguish between a deers vtial organs and then determine whether or not a broadhead went through them or didn't
. I myself (especially on deer I plan to cape) bring the lungs and heart out together by reaching in and grabbing a hold of the larynx and pulling them out in tact.
