Audio Experts Differ On Trayvon Martin 9-1-1 Call

ORLANDO (CBSMiami/AP) – Screams for help heard on a 9-1-1 recording the night 17-year old Trayvon Martin was fatally shot by neighborhood watch leader George Zimmerman may or may not have come from the teen.

In a report released Tuesday, audio experts have gave differing opinions as to whether screams those of Martin or Zimmerman.

While one audio expert said in a report that the screams came from Martin, another audio expert says the shouts were a mix of Martin and Zimmerman.

Attorneys prosecuting Zimmerman for second-degree murder hired the audio experts to compare samples of Martin and Zimmerman's voices with the shouts from the 911 calls.

Martin's family claims the voice is that of the South Florida teen. Zimmerman's father has said in court he believes the cries are from his son.

Zimmerman is pleading not guilty, claiming self-defense. His trial starts next month.
