Evidence indicates that Zimmerman suffered head injuries the night Martin died, though exactly how and why remains a mystery

Mystery?

The mystery is that the MSM has an incredible lack of curiousity of how Zimmerman received such bad head injuries. So they will say that it’s not clear how it happened, because otherwise they might have to admit that Trayvon was not a little angel, just minding his own business.

and, have there been any reports that T. Martin suffered any cuts, bruises, broken noses, etc? Wouldn’t the autopsy show signs that he had been attacked/beaten if Zimm was the aggressor?

No,the state has clearly shown how those injuries were sustained...the concrete paths of that complex repeatedly attacked GZ,striking him both on the face and the back of the head.It was an unprovoked attack...kinda like when and SUV hits a telephone pole,it has a mind of its own.
