A Mobile judge presiding over the capital murder case of accused cop killer Marco Perez has issued a strict gag order on individuals directly involved in the case.

In a written motion filed Sunday afternoon, specially appointed District Judge Ben Brooks effectively banned the Mobile County DA, her assistants and her staff, law enforcement officers involved in the case, Perez, his attorneys and their staffs and investigators, and all witnesses, expert and lay, from making certain statements to the media.

Statements relating to Perez’s and others character, credibility, reputation or criminal record are among some of the stipulations included in the order. Also included are any opinions of guilt or innocence, information that could likely become inadmissible at trial, and the existence or contents of confessions, admissions and statements.

The order expires at the conclusion of the trial.

In his motion Judge Brooks said that the purpose of the restraining order “should be evident.”

He wrote that the “court is concerned that both the State of Alabama and Defendant have a fair trial pursuant to our established rules of procedure and evidence” and that the “the jury selected, will not be exposed to pre-trial publicity or extrajudicial statements during trial to the extent that it would make it difficult to be fair and unbiased, both to the State of Alabama and the Defendant.”

The restraining order comes a week after Perez was brought into court wearing handcuffs that had the last name of slain Mobile police officer Sean Tuder engraved on them. Perez’s defense attorney made a statement to the court suggesting the engraving raised the prospect of prejudice in the trial.

Perez is accused of killing Tuder during a shooting Jan. 20.

Perez’s preliminary hearing is set to commence Tuesday at 3:30 p.m.
