Zimmerman Defense Team to Present Closing Argument Today

Then it's up to the jury

George Zimmerman's attorneys will get one last chance Friday to convince a jury that the former neighborhood watch volunteer killed unarmed teenager Trayvon Martin in self defense.

Mark O'Mara, one of Zimmerman's lawyers, was expected to argue in a closing statement that his client is a conscientious citizen who fired a fatal bullet into a teen while fighting for his life. Prosecutors gave part of their closing arguments Thursday and will also likely get to present a statement Friday after O'Mara wraps.
