(CBS Miami)Prosecutors in the George Zimmerman murder trial are beginning to wind down their case after a week full of presenting forensics evidence and testimony they believe refutes the defendant’s claim of self-defense in the shooting death of Trayvon Martin.
The biggest question remaining for the prosecution is whether either of Travyon Martin’s parents will be called to the witness stand to testify about whose voice is screaming in the background of the 911 calls made right before the shooting.
Martin’s parents, Sybrina Fulton and Tracy Martin, contend it is their 17-year-old son screaming on the calls, while Zimmerman’s father has said it is his son. The screams are crucial pieces of evidence because they could determine who the aggressor was in the confrontation. An FBI expert testified earlier in the week that a person familiar with a voice is in the best position to identify it.
