Ultimately, Zimmerman declined to testify on his own behalf. HLN's Nancy Grace agreed with the move as it would have exposed him to an unpredictable cross-examination. "Look at what happened to Jodi Arias and her 18 days on the stand. It turned the jury against her," Grace said. "Casey Anthony didn't take the stand, and we saw what happened there -- an acquittal."
The defense wrapped its case shortly after Zimmerman announced his decision, but not before calling one final witness to testify about the voice on the 911 call. Robert Zimmerman, George's father, said it was his son shouting for help. Recalling when he was asked by police if he recognized the voice, "I told them, 'Absolutely, it's my son, George."
The jury received the case shortly before 2:30 p.m. ET Friday. The two charges they are considering are second-degree murder and manslaughter -- which was only allowed as a charge Thursday morning. Jurors have the option of deliberating through the weekend and could deliver their verdict at any point during that time.
