The final witness, pending Zimmerman’s decision, was the defendant’s father, Robert Zimmerman, who testified that it was his son who was screaming on the infamous 911 recording of the fatal altercation that claimed the 17-year-old Martin’s life in 2012.
Robert Zimmerman joined his wife, Gladys, in testifying that they believe it was their son George.
By contrast, Trayvon Martin’s mother, Sybrina Fulton, said she was “absolutely” certain that the panicked voice was that of her son Trayvon, with the late teenager’s brother, Jahvaris Fulton, making a similar determination.
