Trayvon Martin's mother, Sybrina Fulton, has taken the stand in the murder trial for her son's death.

As I documented, Martin was fatally shot by neighborhood watch officer George Zimmerman after what the prosecution called a case of racial profiling.

Fulton started her testimony with a prayer, referring to her son as an "angel" in a Twitter post dated before the session.

"I pray that God gives me strength to properly represent my Angel Trayvon. He may not be perfect but he's mine. I plead the blood of Jesus for healing," she wrote.

ABC News noted that she recognized the screaming on the 911 tapes now included in the trial as belonging to her son. Zimmerman' father has stated that he can make out his own son yelling on the tape.
