Trayvon Martin Shooting: Voice Experts Claim Teen's Cries, Not Zimmerman's, Can Be Heard On 911 Call
Before George Zimmerman shot Trayvon Martin on February 26, a 911 call recorded the voice of someone screaming. Whether that person was Martin or Zimmerman -- who police say claimed he was attacked by Martin before the fatal incident -- has been an open question since the calls were released by the Sanford, Florida police department.

The Orlando Sentinel consulted two voice experts to try to settle the debate, and both came to the same conclusion: The cries could not have come from George Zimmerman.
One expert, Tom Owen, used voice identification software to rule out Zimmerman as the source. From the Sentinel:
"I took all of the screams and put those together, and cut out everything else," Owen says.
The software compared that audio to Zimmerman's voice. It returned a 48 percent match. Owen said to reach a positive match with audio of this quality, he'd expect higher than 90 percent.
"As a result of that, you can say with reasonable scientific certainty that it's not Zimmerman," Owen says, stressing that he cannot confirm the voice as Trayvon's, because he didn't have a sample of the teen's voice to compare. Read More
