SANFORD, Fla. (AP) - George Zimmerman's mother says it was her son's screams that can be heard in the background of a 911 call recorded the night her son fatally shot Trayvon Martin.
Defense attorney Mark O'Mara played the 911 call in court after Gladys Zimmerman took the witness stand Friday.
When O'Mara asked her whose voice was screaming, she answered "My son."
Martin's mother and brother testified earlier in the day that it was Martin who was screaming.
Zimmerman is charged with second-degree murder for fatally shooting Martin. He is pleading not guilty, claiming self-defense.
