Watch Mark O'Mara deliver closing arguments in the George Zimmerman trial (videos)

On July 12, 2013, defense attorney Mark O'Mara addressed the six-member, all-female jury in his last chance to win an acquittal for his client George Zimmerman. Zimmerman, 29, faces a maximum sentence of life in prison if convicted of second-degree murder for the Feb. 26, 2012, shooting death of unarmed teenager Trayvon Martin. Judge Nelson ruled on July 11, 2013, that the lesser charge of

manslaughter could be considered by the jury. Second-degree murder carries a penalty between 25 years and life, while manslaughter carries a sentence between 10 and 30 years. Mark O'Mara did his best to convince the jury that Zimmerman shot and killed Trayvon in self-defense, is innocent and should be allowed to return home to his friends, family and life.

Mark O'Mara used several tools in his closing arguments, including a concrete slab, two cardboard, silhouette cutouts and a computer animation. O'Mara referred to the concrete slab as a weapon Martin used when he attacked Zimmerman, and demonstrated the difference between the two heights. Martin stood several inches taller than Zimmerman while he outweighed him. The computer animation illustrated the fight between the two as Zimmerman described.
