SANFORD, Fla. (AP) — The murder trial for the Florida man charged in the shooting death of teenager Trayvon Martin remains set for a June start after a judge Tuesday denied a defense request for a postponement.

George Zimmerman's lead attorney Mark O'Mara presented a motion to have the trial pushed back to November. He argued that prosecutors had been slow to turn over needed evidence.

State attorney Bernie de la Rionda denied the accusation the prosecution had been dragging its feet and said it was rather a case of the defense using inefficient means to secure the information it wanted.
