Evidence keeps trickling in regarding the shooting death of Florida teenager Trayvon Martin on Feb. 26, but so far it has left legal experts and the public with conflicting and murky details.

The latest tidbit – an enhanced image from a police video, which seems to show an injury on the head of George Zimmerman – adds another piece to a puzzle that's still unresolved.

Mr. Zimmerman is the neighborhood-watch captain who identified the 17-year-old Trayvon as suspicious-looking in a call to police, then ended up in a confrontation with the youth that concluded with Zimmerman pulling his gun and shooting Trayvon.


Trayvon's death has stirred a national outcry, with many Americans outraged at the appearance that investigators quickly adopted Zimmerman's side of the story – that he acted in self-defense after Trayvon turned on him.
