The murder prosecution of George Zimmerman in the death of Trayvon Martin marshaled decades of legal experience on both sides of the courtroom.

Leading the defense was Mark O'Mara of Orlando's O'Mara Law Group. For the government, three longtime assistant state attorneys, including Bernardo de la Rionda, would try to convince the jury to hold Zimmerman accountable for the February 2012 shooting death of the unarmed teenager.
