George Zimmerman attorneys seek hearing over voice analysis experts

George Zimmerman appears in court on Tuesday, April 20, 2013.


Attorneys for George Zimmerman filed a motion for an evidentiary hearing to challenge the state's "expert testimony" on voice analysis.

Zimmerman's attorney, Mark O'Mara, filed the motion, saying the court will "need to make a threshold determination as to whether or not any of the several methodologies the experts used in the voice identification are reliable and generally accepted in the scientific community."


O'Mara says jurors could be confused by an expert's testimony and questioned if it would be allowed at the trial.

The motion doesn't state what exactly the voice analysis experts are testing, but previously there have been discrepancies as to whose voice was heard yelling for help in the background of a 911 call. Zimmerman claims he is the one screaming and Martin’s father initially said he could not positively identify the screams as his son's voice. Tracy Martin, however, later said that was his son screaming after, according to his lawyer, he listened to a clearer version of the call.

It's not clear if and when the evidentiary hearing would take place. Zimmerman's next court date is slated for May 28 and his trial is expected to begin on June 10.

Zimmerman is charged with second-degree murder in the shooting death of 17-year-old Trayvon Martin. He has claimed self-defense, but waived his right to a pretrial immunity hearing last week.
