The attorney for the man who shot and killed unarmed Florida teenager Trayvon Martin said Monday he'll seek to get the case dismissed using a traditional self-defense argument and not the state's "stand your ground" statute.

Mark O'Mara, who is defending George Zimmerman against a second-degree murder charge in the fatal February shooting, said the traditional self-defense approach is appropriate because the facts suggest his client couldn't retreat from a beating Martin was giving him.
