April 30, 2013 -  George Zimmerman waives his right to a “Stand Your Ground” pretrial immunity hearing attorneys decide they will instead try this as a self-defense case. If Zimmerman had had a pretrial immunity hearing, a judge would have ruled whether his actions were protected under the "stand your ground" law. If the judge had ruled in favor of Zimmerman, it would have meant that no criminal or civil trial could proceed.

May 28, 2013 - Judge Debra Nelson rules on several motions brought by the defense. Nelson rules that Trayvon Martin's familiarity with guns, his marijuana use, and fights he may have been in cannot be brought up in Zimmerman's trial. She also denies a request to take the jury to the crime scene. Nelson, however, rules that jurors will remain anonymous and will be referred to by numbers only.

June 14, 2013 - Jurors will be sequestered. The trial will take two to four weeks.
