Rachel Jeantel, the young woman who was on the phone with Trayvon Martin the night he was shot, testified on Wednesday at George Zimmerman's trial that Martin was aware that he was being followed.

"A man was watching him … He kept complaining the man was watching him," the 19-year-old told the prosecuting attorney, relating her conversation with Martin of the night of Feb. 26, 2012.

Jeantel said Martin told her the man watching him was a "creepy-ass cracker." She recalled suggesting that the man might be a rapist. She went on to say that Martin told her he was going to try to elude the man, and that the teen left the area but that he was still being followed. Jeantel said she told him to run, but Martin replied that he was close to his father's fiance's house. Shortly after, Martin told Jeantel he would run home and then the phone went dead.

Later in her testimony, Jeantel said that when she called Martin back, he told her "the nigga is behind me." Jeantel said she heard a bump and then the sound of "wet grass." She said she heard Martin say "get off," the call was cut off and she never spoke to Martin again.

When asked whose voice was screaming for help on the 911 audio, Jeantel said she believes it was Martin.
