Okay, here is what I found. At the end, they list things from the scene. There was no blood on the soil. They were unable to recover any bits of brain or bone from the environment. They were unable to recover the bullet after a truly diligent search that DID discover 12 “unrelated bullets”. They mention that there was a blood stain on his face and shirt consistent with contact with other material that may have been his face or may not. They mention carpet fibers recovered from his clothing.
Then they conclude he killed himself on that spot. It seems to me all the evidence they list is pretty convincing he DID NOT kill himself on that spot.
This is the first time I have ever seen this. Also notice it is just at this point the document ends.
