"The strongest evidence in the autopsy report is most consistent with murder. Under EVIDENCE OF INJURY on numbered page 3 we find, "The defect is stellate and, when the wound edges are repositiioned, measures 7.2 centimeters in the horizontal direction and 4.5 centimeters in the vertical direction." This suggests a wound inflicted by a starburst of rat shot pellets which were far enough from the muzzle of the weapon to have separated from one another by as much as 2.83 inches before striking the head. Who would, or could, shoot themselves in the temple like this?" A 3"xunder-2" head wound is perfectly consistent with a common botched gunshot suicide.
The guy puts the gun to the side of his head - but not at right angle - and the bullet glances off in a graze wound. At least one guy who tried actually had the bullet "ride" between skull and scalp - coming out the other side and not harming him much.
"measures 7.2 centimeters in the horizontal direction and 4.5 centimeters in the vertical direction."
That appears to be a "missed from the perpendicular" shot from front to rear. Seems odd. I'd think Vertical angular error would be more likely. But the lack of tattooing or powder residue seems the more odd.
