Voice analyst in Zimmerman trial: ‘Impossible’ to tell age of person heard screaming on 911 tape
Will the prosecutors present anything that might hurt Zimmerman? As of now, it’s a wonder that they were even able to charge him.
Check it out:
The prosecution began the second week of testimony in the George Zimmerman murder trial with a voice analyst who said it was “impossible to determine” the age of the person who was heard screaming on the 911 call.
Hirotaka Nakasone, an FBI audio voice analyst who examined eight audio recordings related to the February, 2012, shooting of Trayvon Martin, said he was unable to identify or even peg an age to the person whose screams were heard on the tape. He said the pitch of one’s voice goes “all over the place” under extreme stress.
It “was not possible to determine” the age of the person who was screaming, for approximately 2.5 seconds, he said under questioning from Assistant Prosecutor Richard Mantei. “Guessing age is a little complicated.”
The issue is critical, because Zimmerman claims to have acted in self-defense when he shot the 17-year-old Martin. Determining who was doing the screaming could go a long way toward bolstering – or undermining – his defense. Prior to testimony beginning in the case, the prosecution had tried to block Nakasone in a Frye hearing, as they sought in vain to admit audio experts that said the voice was Martin’s.
