George Zimmerman’s defense team is calling out specific witnesses being used by the prosecution in connection with analyzing audio heard on 911 calls made the night Trayvon Martin was shot and killed.
In a motion filed Friday, Zimmerman’s attorney Mark O’Mara describes issues with some of the experts being used by the prosecution, and they need to be covered in a special evidentiary hearing.
O’Mara says Tom Owen, an expert for the prosecution, uses a methodology that is not generally accepted by scientists in the same field.
Another expert, Dr. Alan Reich, does not make clear how he came to his conclusions analyzing evidence recordings.
O’Mara writes thtat two other audio experts, Dr. Harry Hollien and Dor. James Harnsberger, will only confuse a jury with their testimony on how they listened to the 911 calls and repetitively and compared them with samples from Zimmerman and Martin.
O’Mara concludes that the 911 call recordings aren’t even suitable for analysis by the voice identification scientific community.
The motion follows one filed by the prosecution Thursday asking the court to prohibit evidence related to a Computerized Voice Stress Analysis test.
State Attorney Bernie de la Rionda calls the test unreliable and inadmissible.
In O’Mara’s motion, he presses for a Frye hearing to go over speaker identification evidence.
