Judge Debra Nelson has ruled that prosecutors will NOT be allowed to use expert testimony analyzing the 911 tapes recorded the night Trayvon Martin was shot.
Nelson heard from both sides regarding the use of that testimony at hearings that finished up on Friday.
Nelson JUST entered the order denying the use of two witnesses planning to testify that it was not George Zimmerman's voice yelling for help on the 911 tapes immediately before the shooting.
They contended that the voice was actually Travyon Martin.
Zimmerman's defense team argued that the tape's audio wasn't clear enough to be properly analyzed.
