Two of the nations leading forensic voice identification experts say it was not George Zimmerman who was heard crying for help in the 911 call recordings in the moments before Trayvon Martin was killed. Sentiments Trayvon’s mother has expressed since she heard the recordings last month.

“Yes I do. I believe that’s Trayvon Martin. That’s my baby’s voice. Every mother knows their child and that’s his voice,” Martin’s mother Sybrina Fulton told Anderson Cooper last week when asked if she believed that was Trayvon yelling for help in the 911 call recordings.

Now two leading experts in the field of forensic voice identification agree with her.

The Orlando Sentinel commissioned Tom Owen, a forensic consultant and chair emeritus for the American Board of Recorded Evidence, to examine the eight different 911 call recordings released by the Sanford Police department last month. His conclusion: It was not George Zimmerman who was screaming for help.
