Trayvon Martin Case: 911 Screams Are Not George Zimmerman, Say Experts

The screams for help heard on a 911 call placed moments before Trayvon Martin died were not from George Zimmerman, say forensic experts.

Independent forensic experts Tom Owen and Ed Primeau both tell the Orlando Sentinel that the voice heard on the call does not match Zimmerman’s. Owen says he used voice match software to determine that there is only a 48% chance that the voice crying for help is Zimmerman’s. A positive match would have resulted in a 90% reading.

“As a result of that, you can say with reasonable scientific certainty that it’s not Zimmerman,” Owen says.
