A judge has denied a request by George Zimmerman's defense team to depose the attorney for Trayvon Martin's parents.

Judge Debra Nelson said the defense failed to show what relevant information Martin family attorney Benjamin Crump had from a woman known as "Witness 8."

Described as Trayvon Martin's girlfriend, Witness 8 originally recounted the conversation she had with him to Benjamin Crump in a recorded phone interview.

Zimmerman's defense team wanted Crump to answer questions regarding what he knows about the witness.

However, an attorney for Crump argued any testimony would harm Crump's attorney-client privilege with the Martin family.

Crump's attorney also revealed that part of the reason Martin's family hired Crump is to help them sue Zimmerman in civil court.

In denying the defense's request, Judge Nelson argued they've known about "Witness 8" for 10 months and haven't deposed her.

Zimmerman's attorneys also wanted to get the addresses of key witnesses, including Martin's parents. Prosecutors argued they were concerned about witnesses' safety, citing a previous witness whose name, address and other information were leaked online.

"This is an extraordinarily short timeline for this case. We are bound by the court's orders and we abide by them. That's why I'm frustrated when we don't get discovery the way we should," O'Mara said after the hearing.

Attorneys were also expected to discuss the timing of Zimmerman's "Stand Your Ground" hearing, but that was not discussed.

The "Stand Your Ground" hearing is currently scheduled for two weeks in late April. However, Zimmerman's lead defense attorney Mark O'Mara said he doesn't know if he can be prepared in time. Judge Nelson has already said she won't push it back, but don't be surprised if O'Mara asks her to schedule it during the June trial.

If the judge agrees with Zimmerman's argument and grants him immunity based on "Stand Your Ground," the second degree murder charge could be dropped and there wouldn't be a need for a trial.

Another hearing is scheduled for March 5.
