 Rachel Jeantel, 19, recounted to jurors in Zimmerman's murder trial how Martin told her he was being followed by a man as he walked through a gated Florida community on his way back from a convenience store to the home of his father's fiancee. 
  
 The case has drawn attention to race _ Martin was black _ and self-defense laws. 
  
 Jeantel is considered one of the prosecution's most important witnesses because she was the last person to talk to Martin before his encounter with Zimmerman on Feb. 26, 2012. 
  
 She testified that Martin described the man following him as "a creepy-ass cracker" and he thought he had evaded the man. But she said a short time later Martin cursed. 
  
 Martin said Zimmerman was behind him, and she heard Martin ask: "What are you following me for?" 
  
 She then heard what sounded like Martin's phone earpiece drop to the ground, and she heard him say, "Get off! Get off!" The phone went dead, she said. 
  
 Zimmerman, 29, could get life in prison if convicted of second-degree murder. 
  
 Zimmerman has claimed self-defense, saying he opened fire after the teen jumped him and began slamming his head against the concrete sidewalk. Zimmerman identifies himself as Hispanic and has denied that his confrontation with the black teenager had anything to do with race, as Martin's family and its supporters have claimed. 
  
 Martin's parents have said they believe that cries for help heard by neighbors came from their son, while Zimmerman's father believes the cries belong to his son. Both prosecutors and defense attorneys believe they could show whether Zimmerman or Martin was the aggressor in the encounter. 
  
 Before the shooting, Zimmerman had made about a half dozen calls to a nonemergency police number to report suspicious characters in his neighborhood. Prosecutors have argued that the calls show his state of mind. He was increasingly frustrated with repeated burglaries and had reached a breaking point, prosecutors say.

 SANFORD — From the witness stand Wednesday, the state's star witness in the George Zimmerman murder trial, Rachel "Diamond" Jeantel, gave her account of Trayvon Martin's last seconds — and they were dramatic. 
  
 While on the phone with Trayvon, he told her a man was following him, someone he described as a "creepy-ass cracker," Jeantel said. He got close enough to Trayvon that she could hear the man say, "'What are you doing around here?'" 
  
 Jeantel then heard a "bump," followed by something she described as "grass sound." Trayvon said, "Get off. Get off," then the phone went dead, she testified. 
  
 Jeantel's account, though, was nearly lost amid the problems and spectacle she created. She used street slang, was sometimes defiant and talked so fast and so softly that it was often impossible to make out her words. 
  
 The court reporter interrupted her a dozen times, asking her to repeat herself. Jurors interrupted, too, although not as often, and stopped when Circuit Judge Debra S. Nelson told them, "You can't ask questions. If you can't understand, just raise your hand." 
  
 They did. 
  
 Defense attorney Don West had problems, too, and kept objecting when Assistant State Attorney Bernie de la Rionda began paraphrasing her answers in an attempt to be helpful. 
  
 Jeantel, the most anticipated witness of the trial, spent 21/2 fascinating, frustrating hours on the witness stand and is to return at 9 a.m. Thursday for more, when West is scheduled to continue his cross-examination. 
  
 When West told the judge he expects that to last about two more hours, Jeantel blurted out, "What?" 
  
 Her most important job is done: telling jurors what she heard in Trayvon's final seconds of life. But she still has some explaining to do, and prosecutors will likely try to fix her reputation. 
  
 She admitted Wednesday to two lies. She told Trayvon's mother, Sybrina Fulton, and family attorney Benjamin Crump shortly after the shooting that she was 16 when she really was 18. She wanted Fulton to think she was a minor, just as Trayvon was, she said. 
  
 And she said she lied, again to Fulton and Crump, when she said she had missed Trayvon's wake because she was in a hospital. 
  
 She made that up, she said, because she did not want to see his body. 
  
 She did not find out until two days after the shooting that Trayvon had died, she said. She also said that when the phone went dead, she thought Trayvon had gotten into a fight and that his father had likely come to his rescue. 
  
 Zimmerman, a 29-year-old former Neighborhood Watch volunteer, is accused of profiling, following, confronting and murdering Trayvon, who was 17 and unarmed. 
  
 Zimmerman says he acted in self-defense after the Miami Gardens teenager attacked him Feb. 26, 2012, in a gated Sanford townhome community. He is charged with second-degree murder. 
  
 Other witnesses 
  
 Jeantel's testimony capped a rocky day for prosecutors. 
  
 Early in the day, they called two neighbor eyewitnesses who heard and saw part of the confrontation between Trayvon and Zimmerman the night of the shooting. 
  
 If jurors wanted clarity from them, they did not get it. |||||
Solution:
One of the prosecution's key witnesses in the George Zimmerman murder trial began her testimony today and recounted how she spoke with Trayvon Martin by phone as he tried to evade the man he described as a "creepy ass cracker" who had begun following him. At one point, when he was near the house of his father's girlfriend, Trayvon apparently thought he had eluded Zimmerman. Rachel Jeantel said she told him to keep running, but "he said, nah, he'd just walk faster." Then Jeantel heard Travyon curse, and he told her that his follower was behind him, reports the Orlando Sentinel. Jeantel, 19, recounted an exchange between the two, with Trayvon demanding to know why Zimmerman was following him and the "hard-breathing" Zimmerman demanding to know what Trayvon was doing in the neighborhood. Then she heard a struggle, with Trayvon shouting, "Get off, get off!" as the phone went dead, reports the AP. Jeantel will be back on the stand tomorrow to wrap up her testimony—much to her displeasure. The Sentinel notes that when defense attorney Don West informed the judge that he had two hours of questioning left, she exclaimed, "What?" In his questioning, West tried to dent Jeantel's credibility. Though 18 at the time of the killing, she admitted that she lied and said she was a minor because she hoped it would keep her out of the case, reports the Huffington Post.
