In the afternoon, records custodian Ramona Rumph returned to the courtroom to introduce five prior non-emergency calls by Zimmerman that the judge ruled the jury could hear:
-- August 3, 2011 -- Zimmerman reports seeing a "black male" who looked like the person who robbed a neighbor
-- August 6, 2011 -- Zimmerman says there have been break-ins in the area, and he saw two possible suspects he described as black males in their late teens
-- September 23, 2011 -- Zimmerman says a neighbor's garage door is open and explains that the neighborhood watch is encouraged to report unusual occurrences
-- October 1, 2011 -- Zimmerman reports two suspicious black males "loitering"
-- February 2, 2012 -- Zimmerman reports a black "gentleman" walking around the neighborhood who keeps going up to a house and walking around the side, but Zimmerman says he does not want to approach the man.
Defense attorney O'Mara pointed out on cross-examination that after the Oct. 1 call, police did make contact with the two men Zimmerman called about. He also claimed that the February 2 call led to an arrest of a person who lived in the community.
The next witness was Rachel Jeantel, a 19-year-old who is expected to be one of the key witnesses in the prosecution's case. She was on the phone with Martin right before the shooting and may have heard the beginning of his confrontation with Zimmerman.
Jeantel said Martin told her a man he described as a "creepy-a** cracker" was following him. According to Jeantel, Martin said he was going to try to lose the guy but then said, "The n***** is still following me."
She said she told Martin to run and the call got cut off. She called back and Martin said he was near his father's girlfriend's house. Soon after that, Martin said the man was still behind him.
Jeantel testified that she then heard Martin say, "Why are you following me for?"
Jeantel said a man responded, "What are you doing around here?"
Then she heard a "bump" and what she described as a "wet grass" sound.
Jeantel testified that she heard Martin say, "Get off, get off" before the call disconnected.
She said she never heard from Martin again and learned he was dead a couple of days later. She testified that she did not go to Martin's wake and she lied to his parents about why, telling them she was in the hospital because she felt guilty that she was the last person to talk to him.
Jeantel acknowledged that she lied about her age when Martin's parents contacted her in March 2012 to ask her to speak to their attorney, Ben Crump. She did meet with Martin's mother and gave her a letter explaining what happened.
Jeantel said she did not know her interview with Crump was recorded and would be released to ABC News. She said she did not want to talk to Crump, but she felt obligated to.
On cross-examination, defense attorney West suggested details of her story changed since that interview. He said she told Crump that Zimmerman's response to Martin was, "I don't know what you're talking about."
Jeantel said that she rushed the interview with Crump and was asked more questions by the prosecutor.
West also noted that, while Jeantel testified that the voice crying for help in the 911 call was Martin's, she previously said in a deposition that she was not certain if it was.
At the end of the day, when Jeantel heard West say he had a few hours of additional questions for her, she exclaimed, "What?"
Did Rachel Jeantel change her story?
Jeantel did return to the witness stand for most of the day Thursday.
West resumed cross-examination and asked Jeantel questions about the letter a friend helped her write to Martin's mother, Sybrina Fulton.
He also questioned her about her first interview with law enforcement, which she said she gave at Fulton's home with Fulton next to her. She said she cleaned up Martin's language when she told her story then to be sensitive to Fulton's feelings.
