Defense requesting delay in Trayvon Martin trial

A judge in the case of a former neighborhood watch leader accused of shooting Florida teenager Trayvon Martin is set to hear arguments on a request by defense attorneys to delay the trial.

George Zimmerman's attorneys will present a motion Tuesday asking Judge Debra Nelson to push the trial from mid-June back to November because they say the prosecutor has been slow to turn over needed evidence. The state attorney has denied the accusation.

Zimmerman is claiming he acted in self-defense in shooting Martin last year and has pleaded not guilty to second-degree murder.

Other pending defense motions include one asking for access to Martin's social media accounts, and another seeking records from an analysis that was done on the cell phone he was carrying the night he died.
