Trayvon's mom: "I heard my son screaming"
Trayvon Martin's mother, Sybrina Fulton testified on Friday that screams from a 911 call were those of her murdered 17-year-old son. The call is a point of dispute in the case against George Zimmerman who has pleaded self-defense in the murder trial. Identifying which of the two men were screaming could be a key piece of evidence in determining who was the aggressor at the time. Martin's brother, Jahvaris Fulton also testified that the screams on the tape were made by his brother Trayvon.
