George Zimmerman Hearing: June 7th
The Frye hearing continues in the George Zimmerman case. Voice analyst Tom Owen testified today.
ABC News has obtained a clip of video from Trayvon Martin's cell phone with his voice. To my ear, Trayvon's voice sounds much deeper than the screams on the 911 call, which again tells me it's Zimmerman screaming.
