I actually corresponded with the pawnbroker a few weeks after the event. The text in the OP is a pretty close match for what I remember, except the digestive system comments were not discussed. At the time, he had not been told about the number of hits on the perp either, as I recall.
Interesting comment about how the bad guy dropped like a brick given that 4 out of 5 bullets entered his head through the left eye, scrambling the brains. Obviously, the guy didn't drop like a brick or he would not have been present in the line of fire for that many shots. Most people don't remain upright with 1 shot that enters the brain, even less rarely with two, and 3 is virtually unheard of, but this guy did. He lasted long enough to be shot at least 5 times of which he didn't go down until AFTER the fourth round enter the brain. Is that not a little strange? If you were the DA, would you not not be questioning how it was that a guy stabbed multiple times managed to put four shots through the left eye of the perp during battle?
As for the issue of being charged or not, things are not always as clear cut as they seem to be in an after-the-fact description by a person cleared of wrong-doing. The DA did his/her job in reviewing thoroughly a homicide case for which there were no good witnesses other than the survivor and no security footage. It would be a bit odd to have a person shot that many times through the eye and the shooting not be with a full auto weapon or the shooting not be an execution as in the case with the OK pharmacist, Ersland who executed his robber. That case went quicker, in part, because the video showed the execution. So this sort of thing does happen. If you read the original thread on the case here on TFL, people were talking about Ersland being a hero. He turned out to be a cold blooded murderer.

So, the DA has to determine whether or not the situation of the case is as described. Was the pawnbroker really acting in self defense when he shot the other guy or was the other guy acting in self defense against the pawnbroker and lost? When the only witness is the survivor, he is the only one who gets to tell his side of the story and so it becomes a matter of a lot of investigatory and forensics work to determine if the story is valid or not.
Don't fault the DA for being thorough. We should be so lucky that other DAs would be that thorough, but sadly they are not. If they were, then maybe fewer folks would be wrongly convicted.
That was "Flimflam" from THR, right? Seemed like a decent guy.
No "flimflam" on THR. I did find this reference...
It was a guy who posted as "flimflam' on rec.guns
