Rachel Jeantel, one of the key witnesses in the George Zimmerman trial was put on the stand Wednesday to tell her account of what happened Feb. 26, 2012, the night that 17-year-old Trayvon Martin was killed.

The 19-year-old woman who claimed to be on phone with Martin minutes before he was shot and killed by Zimmerman took the stand dressed in black.

Zimmerman's attorney, Don West asked Jeantel a number of questions regarding her phone call records with Martin and how many times she spoke with him the day he died. The woman said she spoke with him starting from 12 pm and throughout the day. When West pulled out the phone records indicating the exact times she was on the phone with Martin, West said that the phone calls started at 6pm. Jeantel said the phone records weren't true.

Jeantel also denied that she and Martin were in a relationship, but were only friends. She said they hung out as friends in their Florida neighborhood.

Jeantel said she didn't know she was going to be a witness after people told her that Zimmerman was reportedly arrested the same day Martin was killed.

NewsOne reported that Jeantel described the last seconds of Martin's life on February 26, 2012:

"He said this man was watching him, so he put his hoodie on. He said he lost the man," Martin's friend said to Crump. "I asked Trayvon to run, and he said he was going to walk fast. I told him to run, but he said he was not going to run."

Jeantel claimed that Zimmerman followed Martin moments before he was shot to death. 

"Trayvon said, 'What, are you following me for,' and the man said, 'What are you doing here?' Next thing I hear is somebody pushing, and somebody pushed Trayvon because the head set just fell. I called him again, and he didn't answer the phone."
