(Sanford, FL)  --  Lawyers representing George Zimmerman are accusing prosecutors of withholding information and also say they're getting tired.  After a court session that lasted more than 13-hours, Judge Debra Nelson walked out of the courtroom, ignoring defense lawyers who asked for a postponement. 

Judge Debra Nelson has repeatedly shown concern for the nine remaining jurors who have been sequestered for two-and-a-half weeks, even missing Independence Day with their families.  The judge is expected to rule on outstanding issues involving Trayvon Martin's text messages and a computer simulation of the night the teen was shot and killed.  The defense is expected to rest its case today.
