SANFORD, Fla. (AP) - The prosecution has begun it's rebuttal to the defense's closing arguments in George Zimmerman's second-degree murder trial.
Prosecutor John Guy on Friday began countering defense attorney Mark O'Mara's contention that Zimmerman shot Trayvon Martin in self-defense.
O'Mara said the prosecution's case was full of gaps and built upon a series of "could've beens" and "maybes." He told jurors the burden was on prosecutors, and he said they hadn't proven Zimmerman's guilt beyond a reasonable doubt.
A jury of six women could begin deliberations as early as Friday afternoon.
Zimmerman is charged with second-degree murder, but jurors can also choose manslaughter. A conviction on either charge carries a maximum penalty of life in prison.
