SAN ANTONIO — Olmos Park police have released more details about why they are searching for missing mother Suzanne Clark Simpson at a landfill in southeast Bexar County.

In a statement released to city residents by Olmos Park Police Chief Fidel Villegas, officials said evidence, statements and further police investigation led officers to the landfill, the location of which investigators declined to disclose.

Authorities are on site for the third day on Tuesday as they continue their search efforts.

In a post on X, formerly Twitter, San Antonio Police Chief William McManus said Olmos Park police had asked SAPD for help in the search. McManus said 25 cadets assisted on Tuesday.

The Texas Department of Public Safety previously told KSAT that the landfill is one of four areas they searched in connection with Simpson, a mother of four from Olmos Park and a real estate agent, most recently on Sunday, Oct. 6 , was seen. Her husband, Brad Simpson, was arrested last week on charges unrelated to her disappearance.

The search of the landfill for evidence of her disappearance involved a sealed search warrant, according to sources familiar with the investigation. The arrest warrant was signed Saturday after it was filed by the Texas DPS, sources told KSAT.

Sealed warrants are common in federal cases but are rarely used in county cases. The seal can remain in place for up to 31 days and can only be used if an attorney proves to a court that publicly disclosing the contents of the case would harm the case.

Olmos Park police said the Simpson family has been helpful and supportive in the search for Suzanne Clark Simpson.

“We are confident that there is a good chance of recovering Suzanne from this location,” the statement said.

Olmos Park PD thanked other law enforcement agencies for their assistance in the investigation.

Villegas’ full statement can be found below:

“Today, OPPD Police continued their investigation into the Suzanne Clark Simpson case.

“The Simpson family have been very helpful and supportive, although they need support and understanding at this time.

“The OPPD met with family members to discuss the phase of the investigation we are in – a search phase. The search is taking place at a landfill located to the southeast.

“We are confident that there is a good chance of recovering Suzanne from this location.

“Evidence, statements and solid police investigations led us there. This would not be possible without the help of many other LE agencies and some non-LE agencies. However, the Texas Rangers and DPS are at the forefront of this investigation and the OPPD is working alongside them.

“We ask you to pray all the best for the family in the coming days. We feel the support of the community and especially the family and will do our best to help the family and our incredible community.”
