Tiereney Nicole Anderson, 34, was shot and killed in her Houston home in the 10100 block of Wild Hollow Lane on August 4, 2019. He then shot himself and called 911, claiming he had acted in self-defense.

Prosecutors presented evidence that Mark Anderson had a history of domestic violence and had threatened to shoot her three months earlier. Physical evidence and inconsistencies in his account undermined his self-defense claim, and the case proceeded to conviction. On February 4, 2023, he was sentenced to 38 years in prison for Tiereney’s murder.

Tiereney’s death underscores the deadly escalation that can occur in domestic violence situations. If anyone knew Tiereney, her movements that day, or has information relevant to the case, please come forward.
