Shouts of help that prosecutors say were from Trayvon Martin, in a voice recording just seconds before he was shot dead by George Zimmerman, will come under scrutiny when Zimmerman's trial commences on June 10.
A new court filing made on Tuesday has indicated that Zimmerman's defense attorney, Mark O'Mara, will look to question whether the voice crying out for help is actually Martin, or whether it is in fact Zimmerman.
Already, prosecutor audio experts have analyzed the recording and have said that the voice calling for help is that of the victim, Martin. However, in the new motion, O'Mara writes that the state's audio experts are using inaccurate methods to identify the voice. He is applying for the judge to throw the audio recording out of court and block it from being used as evidence against his client.
The new motion does not explicitly detail which recording O'Mara is talking about, but most have interpreted the request to mean the audio recording of George Zimmerman's 911 call.
The recording is thought to be one of the core pieces of evidence in the trial against Zimmerman, who is being accused of second degree murder, after shooting Martin dead on Feb. 26, 2012.
Zimmerman, who was a volunteer neighborhood watchman, has admitted to killing Martin, but is pleading not guilty to his murder, saying that he feared for his own life and was acting in self defense.
The 911 recording allegedly shows that Zimmerman was following Martin, and at one point a cry for help can be heard. However, those cries for help cannot be heard clearly on the recording – so much so that the FBI has admitted the recording is too poor for them to take a side on the claims about who they belong to.
However, prosecutors have adamantly claimed that the voice is that of Martin. The victim's parents as well as some audio experts are believed to have been prepared by the prosecution to testify about the recording in the trial.
Two audio experts are listed as prosecution witnesses at the moment, and both are said to have used different techniques to analyze the recording, and both came to the same conclusion – that the cries for help are from Martin.
However, O'Mara is arguing the evidence is unreliable and should not be allowed into evidence. It is also believed that the defense will argue that it is impossible to tell whether the voice is that of Martin or Zimmerman, and that they too can present witnesses and experts who claim it is their client screaming for help.
If the court rules for the defense on this point it would be considered a huge win for the defense team.
