Two forensic experts told a Florida newspaper the person screaming in the background of a 911 call was not George Zimmerman the night teen Trayvon Martin was shot.
According to the Orlando Sentinal , the two leading forensic voice identification experts who listened to a 911 call from a neighbor at the gated community where Martin was shot told the Sentinal that the screams didn’t match Zimmerman’s voice.
Tom Owen, forensic consultant for Owen Forensic Services LLC and chair emeritus for the American Board of Recorded Evidence, used sophisticated voice match software.
Owen said there was only a 48% chance that it was Zimmerman crying for help on the tape and that usually, a positive match rates higher than 90%.
“As a result of that, you can say with reasonable scientific certainty that it’s not Zimmerman,” Owen said.
Owen is also the former chief engineer for the New York Public Library’s Rodgers and Hammerstein Archives of Recorded Sound. He said he couldn’t be sure that the voice was that of the teen because he didn’t have a sample voice of Martin’s.
Ed Primeau, an audio engineer and forensics expert from Michigan, claimed his research led him to believe he heard the teen screaming for his life.
Primeau said; “I believe that’s Trayvon Martin in the background, without a doubt.”
The research Primeau used was different from that used by Owen.
Primeau didn’t use Owen’s CSI-style voice analysis software. He instead used audio enhancement and his own ears to compare the screams to Zimmerman’s voice on a 911 call right before he shot Martin.
“That’s a young man screaming,” Primeau said.
The two voice experts who have contradicted Zimmerman’s story that he shot Martin in self-defense during a struggle are a severe blow to his claim.
This could possibly be the second contradiction to Zimmerman’s story of the incident.
Zimmerman told friends that he suffered a broken nose and wounds on the back of his head during the struggle with Martin.
But a police station video appeared to show Zimmerman, as he was taken into custody soon after the killing, without any bruises, cuts or blood stains on his clothes.
Zimmerman was not arrested and has since gone into seclusion.
