ORLANDO, Fla. -

A judge ruled Monday that the lawyers for the woman suing Casey Anthony for defamation can subpoena her--if they can find out where she is.

Zenaida Gonzalez is suing Anthony for defamation, claiming Anthony slandered her when she told police a nanny named Zenaida Fernandez Gonzalez took Caylee in June 2008.

Gonzalez's attorneys told the judge they wanted Anthony's address to subpoena her to testify in the trial. The judge would not release Anthony's address, but also ruled Gonzalez's team can subpoena her-if they can find her themselves.

Cheney Mason said he would have filed a federal lawsuit if the court had released his client's address.

He also talked about the death threats both he and Anthony's defense team have received.

"Every member of defense team has received multiple death threats, continuously since July 5," Mason said. "Were you here? Did you see the mob out here? They were only missing the white hats and the pitchforks."

The civil trial is set to start April 10, but both Gonzalez and Anthony's attorneys are asking for a trial continuation.

A judge denied a motion by Anthony's civil attorneys last week to delay the trial.

If the defense's motion for summary judgment was granted entirely, it would have led to dismissal of the case without a trial being necessary.

It's unclear if Anthony will attend the trial.
