Having seen several accidental/suicidal self-inflicted wounds from M16 rifles in which a muzzle contact or arms-length shooting distance was involved, I can tell you that the results look nothing like the result of a hit from a 9mm or .40 caliber handgun fired from several feet away.
The police and coroner's press conference statements that the gunman *killed himself with a self-inflicted wound fired from his shotgun* have now been shown to be deliberate lies at worst and erronious at the least, since we now know that the long gun in his position was a .223 caliber rifle...and not the reporteed *shotgun* that wasn't in his possession, though several of the earliest responding cops on the scenes showed up with the scatterguns from their cruisers.
My suspicion is that a very close-up *certainty* shot was made, either just after the shooter went down, or by one of the first cops on the scene. And by continuing to bring the light of public interest on the case, Larry Bourbonnais is unwittingly a part of unravelling their coverup of the actual events, and accordingly has to be silenced, one way or another.
This brings up an interesting point. During one of Larry's early interviews he stated when Jeanne downed the shooter they both approached the body and Larry told her to "put one in his head." Her response was "he's already dead." Larry said he then picked up the shooters hand gun and said it was jammed. Perhaps he is the one to put "one in the shooters head."
