The findings of state audio experts who examined the 911 calls made the night Trayvon Martin was shot and killed were released Tuesday. 

In call three, made by a woman who reported seeing the confrontation outside her home, screams can be heard and the audio experts came to different conclusions on who is heard screaming in the background.

Forensic Communication Associates in Gainesville examined the 911 call and broke it down scream by scream. 

Senior Consultants Harry Hollien and James Harnsberger were given CD’s containing voice recordings of both George Zimmerman and Trayvon Martin to use for comparison.

Hollien and Harnsberger concluded that “only a little over eight seconds of speech was found available for assessment.”

They identified 16 samples of screams in that time frame and concluded that screams one and eight were made by Trayvon Martin and screams 14 and 16 were made by George Zimmerman.

Another analysis of the call was done by Forensic Acoustics Consultant Alan Reich.  He said his findings show that the cries came from Trayvon Martin.

He claims to hear Zimmerman make a seemingly "religious proclamation" saying, "This shall be."

The analyst describes the tone as that of an evangelical preacher or a carnival barker.

The analyst then reports hearing a higher pitched voice believed to be Trayvon Martin saying, "I'm begging you," which happens simultaneously with speech by the 911 operator and George Zimmerman.

In May 2012, Reich was retained by The Washington Post to do the same analysis and came to the same conclusion at that time.

Zimmerman’s lead defense attorney Mark O’Mara said the only thing the audio analysis shows is that the recording is not long enough, or good enough quality, to prove anything. “There are two of them, and they seem to be internally inconsistent, because they seem to be saying different things. One witness says he thinks he hears certain things, and another witness says he doesn’t hear that. And none of them can come up with something that is precise … or that is something they can testify with.”

O’Mara said since the analysis came out just a month away from the beginning of the trial, he may ask for a delay in the trial so his defense team can have enough time to look at the science that was used to analyze the call.  He also said he plans on challenging those methods used at an evidentiary hearing he has asked for later this month.
