As the search for missing Texas mother of four Suzanne Simpson moves into its second week, authorities are searching a landfill after searching several other locations, including the woods near her home outside San Antonio. 

"Currently, they have moved to a location, a landfill … just outside San Antonio. They've been there for the last two days … searching for evidence," Sgt. Deon Cockrell of the Texas Department of Public Safety told Fox News Digital. 

"We're just continuing the investigation from one stage to another. If it leads to somewhere else tomorrow, we'll go to that location tomorrow," Cockrell added.

Simpson, a 51-year-old luxury real estate agent, was at The Argyle club in Alamo Heights before her disappearance on Oct. 6. She was seen fighting with her husband, Brad Simpson, according to police.

Authorities announced they found two items of interest in the woods and recently found "possible evidence" inside the Simpson home, Olmos Park Police Chief Fidel Villegas said Thursday.

Brad Simpson, 53, was arrested Wednesday in Kendall County on a family violence charge in relation to his wife's disappearance, Olmos Park police said. 

On Sunday night, Oct. 6, there was a "disturbance" between the Simpsons at The Argyle, Villegas said at a previous press conference broadcast by WOAI News 4. The couple had been at a birthday party there, according to San Antonio Reports.

Police have tried to interview Brad Simpson, but he has been "uncooperative," Villegas said.

"They're still trying to get information as to her whereabouts; whether he had anything to do with it or not, I can't really say," Cockrell told Fox News Digital.

A neighbor told police he saw Brad and Suzanne physically fighting each other and later heard screams coming from a nearby wooded area, the outlet reported, based on a police report. 

"That night we think she was in distress … it's very suspicious, though, that obviously she's not going to work, and she's not checking in on her children," Villegas said Thursday.
