A Florida judge has denied a request from George Zimmerman's defense attorney to acquit the neighborhood watch volunteer of second-degree murder for fatally shooting Trayvon Martin. The defense has claimed the State has not met its burden of proof. Prosecutors rested their case Friday, a day in which both George Zimmerman's and Trayvon Martin's mother each testified that it was her son, not the other woman's, who can be heard screaming for help on a 911 call. Judge Debra Nelson denied a request by defense attorneys to acquit Zimmerman of second-degree murder after prosecutors rested. Defense attorney Mark O'Mara argued that the state didn't prove its case, and that Zimmerman was acting in self-defense. Prosecutor Richard Mantei told the judge Zimmerman was a liar and had changed his story. George Zimmerman's mother says it was *he*r son's screams that can be heard in the background of a 911 call recorded the night her son fatally shot Trayvon Martin. Martin's family testified earlier in the day that it was Trayvon who was screaming. Zimmerman is charged with second-degree murder for fatally shooting Martin. He is pleading not guilty, claiming self-defense.
