The Trayvon Martin Killing – In the Media and the Press

Over the last few days, I’ve been contacted by news sources wanting to interview me about voice identification.  Some 911 recordings had been released a week prior from the Trayvon Martin case out of Florida.

Reporters asked me about voice identification reliability.  Voice identification is a reliable science when done properly. Trying to determine who is screaming in the background of a 911 call is not easy but seems to be of great significance since these were the final hours of this young man’s life.

I became interested in this case and decided to listen to and peruse the 911 recordings.

I literally stumbled upon the link of 911 calls from http://motherjones.com/politics/2012/03/what-happened-trayvon-martin-explained#transcript

I listened to the 911 calls and recorded them into my audio forensic computer to critically listen to the events.  Two of the 911 calls are very interesting: George Zimmerman’s call and the woman who called 911 when she heard screaming outside her home (which we can hear clearly in her 911 call recording).

This second recording is the same recording where the gun shot is heard that killed Trayvon.

I am not writing this to judge but rather to present the facts as they occurred from a forensic perspective.

As an audio forensic expert I want to make clear that this is not formal voice identification and not meant for legal purposes. It is not a statement of my opinion but rather a presentation of facts as I hear them in two particular 911 recordings.  I believe you will hear what I hear.

Listen carefully to the 911 call segment I chose from George Zimmerman.   Then listen to the tone of the male voice screaming for help in the background during the second 911 call. Can you see the series of events in your mind’s eye?
