Been doing a little searching on the “round in chamber” question. I found one blog making that claim, but also found another one quoting a Boston Herald story saying an expended round was found at scene. That was my recollection, but haven’t found the document again. The original police report says nothing either way. The scene tech’s report should be released as part of the discovery in coming days, though there’s still a delay possible because the iss ue of redaction of witness names hasn’t been resolved completely.

Also found some statements about the magazine being full, but that’s subject to dual interpretations.
Perhaps if one was shot at close range with a shotgun with 00, or from a sniper’s rifle, or possibly even a large claiber handgun such as a .44mag.
In this situation, I would expect any entrance wound fluid to have been contained by Martin’s hoodie.
You know, there is no reason for anyone to be playing CSI in this matter, and to do so is folly. The fact that Zimmerman was never initially charged and the fact that a special persecutor had to be brought in and subsequently charged him with 2nd degree murder of all things is enough for anyone to see that they are trying to railroad this man.
