Texas Realtor Suzanne Simpson vanished over four months ago, and her husband, Brad Simpson, who is charged with the mother of four’s murder, returned to court this week as his defense looks for holes in the evidence.

During a hearing Wednesday in a San Antonio courtroom, prosecutors said they were expecting to have five to six terabytes of evidence coming from the Texas Rangers, and defense attorneys said they still needed about one terabyte of evidence to go through before they could move forward with a motion to quash the indictment, KSAT reported.

Texas Department of Public Safety spokesperson Deon Cockrell confirmed with Fox News Digital that authorities are still working to find Suzanne’s remains. Law enforcement in November said there are no signs of her being alive, according to an affidavit. 

“They won’t stop looking,” Cockrell said. “We still want to find her, just as much as her family does.”

After Simpson’s indictment, friends and family of Suzanne gathered at a memorial Dec. 20 to honor her life.

The private ceremony was held at First Presbyterian Church in downtown San Antonio with hundreds in attendance.

Brad Simpson’s next court appearance is scheduled for March 12. Simpson’s attorney did not immediately respond for comment. 

The Bexar County District Attorney’s Office said it does not comment on pending cases.
