Defense attorney Mark O'Mara told reporters that Zimmerman wanted to testify but his attorneys felt he had already told his version of events in multiple police interviews played for jurors.
"I think he really wanted to be able to interact with this jury and say to them, 'This is what I did and this is why I did it. And as importantly, this is what was happening to me at the time that I decided to do what I had to do,' " O'Mara said. "So in that sense, yes, I think he wanted to tell his story."
Still, O'Mara said his client is "worried" as he faces up to a life sentence in prison for what O'Mara called a classic case of self-defense.
The defense started its case last Friday and presented half as many witnesses in half of the time that prosecutors did. Friends, parents and an uncle of the defendant testified that it was Zimmerman screaming for help on a 911 call that captured sounds of the fatal fight. Martin's mother and brother had testified for the prosecution that it was Martin yelling for help.
Zimmerman's father, Robert Zimmerman Sr., was the last witness called by the defense on Wednesday, and he said it's his son yelling for help on the call.
Attorneys also called a forensic pathologist who testified that the forensics evidence supports Zimmerman's account of what happened.
Zimmerman has pleaded not guilty to second-degree murder. On the night of the fatal scuffle in February 2012, Martin was visiting his father and his father's fiancee at the same townhome complex where Zimmerman lived.
The defense rested on a day when the judge made two rulings preventing them from introducing certain evidence. Defense attorneys had wanted to present text messages from Trayvon Martin's cellphone that discussed fighting and an animation depicting Zimmerman's fatal fight with Martin. But Nelson sided with prosecutors, who had argued the animation is inaccurate and the texts were irrelevant.
O'Mara said the defense would use the animation in closing arguments.
