The search for missing mom Suzanne Clark Simpson has entered its third week, while her husband remains behind bars and refuses to cooperate with the investigation.

Police and search teams have searched four locations around San Antonio, uncovering no new evidence in the mom’s disappearance. After four days, police have ended the search at a landfill in southeast Bexar County. Authorities said they focused on the site after GPS data led them there and were confident they would recover Suzanne’s remains, but now admit they found no evidence during the search.

Olmos Park Police have resumed their search for Suzanne Simpson in wooded areas around Olmos Park. They have enlisted the help of Texas Search and Rescue and continue to ask the public to leave the search to professionals. Foot searchers and dog teams are combing several areas for any trace of Suzanne.

At his arrest in Boerne two weeks ago, Brad Simpson was charged with unlawful restraint and assault. However, the husband of the missing woman is now also facing a federal gun charge, 10 years in prison, and a $250,000 fine. Simpson’s family turned over his arsenal of weapons after Suzanne’s disappearance, including an unregistered Grand Power Stribog SP9 A3, a short-barrel rifle. He also owned several silencers.

Simpson’s defense attorney claims police are manipulating public perception of his client with “ludicrous” charges. Steven Gilmore repeats that Simpson reported Suzanne missing immediately after learning she missed kindergarten pickup.

He also insists Simpson wanted to cooperate with Olmos Park police but suspected authorities were trying to obtain an arrest warrant when Chief Villegas rescheduled their follow-up interview three times.
