SANFORD, Fla. (AP) — An expert for George Zimmerman discounts the methods of prosecution experts who claim screams captured on a 911 call belong to 17-year-old Trayvon Martin and not the former neighborhood watch volunteer.
Voice-recognition researcher James Wayman was called Monday evening by defense attorneys. One expert in a report identified Martin as the source of the screams, and the other testified at a pretrial hearing that those didn't match Zimmerman's voice.
Wayman doubted the screams came from just one person and said the 911 call was too brief to draw conclusions from.
Meanwhile, prosecutors and defense attorneys are seeking a pool of 40 potential jurors who have been screened for any influence of pretrial publicity before moving to a second round of questioning. By Monday, they had interviewed 49 potential jurors.
