Ron Brown had a slug betwixt the eyes, but it was an “accidental” plan crash.

The .45 caliber hole was in the top of his head not the front.
The X-rays before they "disappeared," showed small metal fragments splayed though his brain which were consistent with what a pre-fragmented round would do.

Maybe as the plane crashed, the turbulence pushed his forehead down hard on a loose bullet?
