O'Mara indicated at trial he will dissect the recording of Zimmerman's 911 call and point to evidence of the wounds Zimmerman said he suffered that night.

"I believe, you know, again, the evidence is what it is and that's for a jury to determine," O'Mara said. "But a close reading or looking at that tape and all the evidence that followed, particularly George's injuries and Trayvon's lack of injuries but for the fatal gunshot, suggest that George did not begin the fight, did not continue the fight and actually was the victim of the attack rather than the other way around."

But a lawyer for the Martins said the fight against "senseless gun violence" will continue.

"He went home and slept in his bed the night he killed Trayvon," attorney Benjamin Crump said. "And that wasn't equal justice."

Crump then led a chant of "Hoodies up! Hoodies up!" at the vigil.
