Audio experts differ on whether shouts for help on 911 calls are those of defendant George Zimmerman or of his shooting victim, 17-year-old Trayvon Martin.

One New Jersey-based expert said the screams came from Martin, while a Florida-based audio expert said the shouts were a mix of Martin and Zimmerman.

George Zimmerman's DNA and his alone was found on the gun that killed Trayvon Martin in February, according to DNA test results released by officials Wednesday.

The Florida Department of Law Enforcement found Zimmerman’s DNA was on the gun but not Martin's; it is undetermined whether Martin's DNA was on the holster.

George Zimmerman appeared on Fox News with Sean Hannity last night and issued an apology to the parents of Trayvon Martin.

But the murder suspect also told his interviewer that he doesn't have any regrets over the February incident, saying he wouldn't change much at all regarding his actions on that fateful day - not leaving his car, not owning a gun - and that the shooting of Martin was "all God's plan."
