Evidence continues to emerge casting doubt on George Zimmerman’s claim that he acted in self-defense when shooting Trayvon Martin. A forensics expert has determined it was not Zimmerman’s voice crying for help on the 911 call placed by a neighbor right before Zimmerman shot Trayvon dead. Sanford police have said they believe the voice pleading for help was Zimmerman’s, but Trayvon’s parents say those cries came from their son.

911 Dispatcher: “OK. Does he look hurt to you?”

Caller: “I can’t see him. I don’t want to go out there. I don’t know what’s going on.”

911 Dispatcher: “Do you think he’s yelling 'help'?”

Caller: “Yes.”

911 Dispatcher: All right, what is your [gunshot heard] number?

Caller: “Just, there’s gunshots.”

Now, Tom Owen, the chair emeritus of the American Board of Recorded Evidence, has said he has used voice identification software to rule with 99 percent certainty that the cries are not Zimmerman’s. Another expert interviewed by the Orlando Sentinel reached the same conclusion.
