SAN ANTONIO — The sister of Suzanne Simpson, a mother of four who went missing in October 2024, is facing harassment charges after investigators say she repeatedly contacted family members of Suzanne’s husband and accused them of her sister’s murder.

Teresa Lynn Clark, 55, is charged with four counts of harassment in connection to an incident on Dec. 12, 2024 involving four family members of Brad Simpson.

Since Suzanne’s last sighting at the Argyle Club in Alamo Heights on Oct. 6, 2024, her husband, Brad Simpson, has been charged with murder in connection to her presumed death.

Investigators say Clark has constantly harassed the family since Brad Simpson’s arrest, accusing the family of killing her sister through voice messages and emails. The voice messages ranged from several seconds long to several minutes and were repetitive, according to court documents.

An affidavit states Clark told the family they “Don’t know who they are messing with!” and that they will not get away with this. Investigators say Clark seemingly picked family members at random and called them numerous times in the evening hours usually after midnight.

Despite being told by law enforcement and the family to stop contacting them, investigators say Clark continued the “barrage” of messages and even went on a “social media campaign” in an effort to badmouth the family.

Jail records show Clark was arrested on Thursday in Travis County and is expected to extradited to Bexar County. As of 10:15pm an official with Central Records at the Bexar Cunty Detention Center said she is still in custody.
