Trayvon Martin Shooting: Voice Experts Claim Cries Heard On 911 Call Were Not George Zimmerman's

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. (WARNING: Above audio is disturbing.)
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.

Another analyst came to a similar conclusion using different technology.
The voice analysis is the latest piece of information to cast doubt on the narrative, advanced by Zimmerman and his family, that the Neighborhood Watch volunteer was attacked by 17-year-old Travyon Martin. A police video this week showed no blood or bruises on Zimmerman in the aftermath of the incident, while Martin's funeral director said he saw no signs of a struggle on the teen's body.

CORRECTION: A previous headline for this story stated that voice experts claimed the cries on the 911 call came from Trayvon Martin. In fact, they only said that the cries did not come from George Zimmerman.
