All we can infer from the autopsy report is that it was “at least 1 to 2 feet away”. The eyewitness reports seem to suggest it was quite a bit further, but nothing at this point leads to the conclusion that the shooting was “1 to 2 feet away”.
Upon further review, I agree that the autopsy report might not be able to accurately ascertain the distance. The people who would nail that down would be the crime scene investigators.
