6. I don't think there were witnesses to the shooting, but there was the 911 call

From somebody who apparently witnessed the pre-shooting altercation.

This witness has said that the two were fighting and that Trayvon had the upper hand when he called 911. Then he ran upstairs and heard the shot. When he looked again, the tables had turned. The person who had previously had the upper hand was now lying on the ground shot.

So he didn't see the actual killing, but he apparently saw what happened right before. I believe he's probably a credible witnesss. My opinion is that Zimmerman confronted Trayvon, there were fisticuffs, and Zimmerman shot Trayvon in that altercation.

What that means legally I honestly don't know. It's probably not first-degree murder, but it certainly could be a lesser murder or manslaughter charge. But I don't have much knowledge of the law so I can't say.
