Thus demonstrating that 'Witness 5' has not a single clue about what she's saying. Shooting TM in the leg is not an option if he's on top of you beating your head. I personally think that there was a struggle over the pistol, and it happened to be pointing at TM when it went off - we'll see as the evidence comes out at trial.
By the way, as to "scrawny little kid", if nothing else TM seemed to be in shape. Last I heard his stats were 6' 2", 158 lb, versus 5' 9" 170 lb GZ. That'd be a reasonable boxing matchup, stat-wise, but beyond that everything changes when one person lands an unanticipated first blow. I think it's a fair guess that 'Witness 5' knows not the first thing about unarmed combat - including that a reasonably skilled person can kill another with bare hands in well under a minute.
The full transcript of the autopsy is available here. I tried to find the original site, but all I came up with was the Huffpost link, sorry. At any rate, the autopsy is some actual hard data as opposed to the endless speculation out there. One thing I hadn't heard before is the bullet struck the right ventricle of TM's heart, so there was never any chance of his survival.
At any rate, ABC was irresponsible to write yet another slanted article about this case. Shameful.
Here’s the full autopsy report along with the toxicology results.
