An investigator with a Florida prosecutor's office said on Friday morning that he doesn't know whether it was George Zimmerman or Trayvon Martin who started the fight that resulted in Martin's death on Feb. 26.
Zimmerman's defense attorney Mark O'Mara asked investigator Dale Gilbreath about the evidence that had been gathered in the case.
"Do you know who started the fight?" O'Mara said.
"Do I know? No," Gilbreath replied.
"Do you have any evidence as to who may have started the fight?"
