On the contrary, Martins father Tracy said that it WASN'T the voice of his son Trayvon that he heard screaming on the tape. His girlfriend also said that she didn't know if it was Trayvon screaming for help.<quoted text>
When questioned by the FDLE, instead of the witness leading, witness correcting, witness coaching, inept Sanford PD, Witness John admits he doesn't know who was calling for help, it was too dark to see their mouths.
In addition to Martin's family saying it was Martin heard calling for help, 2 different audio voice experts, using 2 different methods of examination, would stake their reputations on the fact that it was not Zimmerman calling for help.
The audio experts never received a copy of Trayvon's voice with which to compare the audio. Can you tell me why the Martins never gave investigators a tape / digital recording of their sons voice?
