SANFORD, Fla. -- The judge in the murder trial of George Zimmerman has denied a motion from the defense to delay the trial six weeks, and the trial is still set to begin June 10.

Zimmerman's defense attorney Mark O'Mara had requested the delay in light of new voice analysis the state plans to introduce as evidence during the trial. O'Mara had said he needs more time to prepare.

The ruling was made in a hearing Tuesday morning, along with several other important motions in the case.

Trayvon Martin's alleged marijuana use and the text messages he sent before his death will not be allowed in the second-degree murder trial, Nelson ruled.

The defense argued that alleged drug use by the teenager, as referenced by several text messages he sent, could have affected his behavior.

The state did not want it allowed in trial, and Nelson granted the state's motion, but Nelson said she might allow expert testimony on marijuana found in Martin's system.

The defense also argued that text messages sent by Martin prove he was hostile and angry. The judge ruled that the messages cannot be mentioned in the presence of the jury.

Martin's alleged history of fighting and his school records must be kept out of opening statements, but they can be brought up during trial.

But Martin's fake gold teeth cannot be referenced during trial.
Zimmerman's wife, Shellie Zimmerman, can be deposed by the state, Nelson ruled. She'll be able to invoke her Fifth Amendment right on a question-by-question basis.

The jury pool will not be sequestered, and the trial jury will not be taken to the shooting scene. Nelson described that idea as a "logistical nightmare."

Zimmerman did not attend the hearing, but Martin's family was present.
