Trayvon Martin's mother said in court on Friday she recognized the voice of her son screaming for help in an emergency call on the night the Black Florida teenager was shot dead by neighborhood watchman George Zimmermann.
Sybrina Fulton's testimony came as the state was preparing to wrap up its murder case against Zimmerman after nearly two weeks of testimony.
The prosecution has sought to expose inconsistencies in his account of the fight in Sanford, Florida, in February last year that ended with Martin's death.
Fulton told jurors she was certain it was her son who can be heard screaming for help in the background of an emergency call made to police moments before he died. "I heard my son screaming," said Fulton, who added that she first heard the recording in the office of the mayor of this town near Orlando where her son died.
