Expert says screams on 911 call aren't from Zimmerman.
SANFORD, FL. (AP) — An expert hired by an Orlando newspaper is testifying that screams for help on 911 calls don't match neighborhood watch volunteer George Zimmerman's voice.
Tom Owen testified Friday at a hearing on whether voice identification experts can be used at Zimmerman's second-degree trial for fatally shooting 17-year-old Trayvon Martin. The trial starts Monday and Zimmerman is pleading not guilty.
Owen was hired by the Orlando Sentinel last year to compare Zimmerman's voice with screams for help captured on 911 calls made by neighbors. He says Zimmerman's voice doesn't match the screams.
An FBI expert testified a day earlier that there wasn't enough clear sound on the 911 recordings to determine whose voice it was. He also said the concept that individuals have unique voice-prints that could identify them was misleading.
