On April 7, 2014, 18-year-old Debbie Thammavongsa was killed execution-style in her Dallas home alongside her mother, 50-year-old Ammy Soumphonphakdy; an unidentified male victim survived. Debbie called 911 before she died. The slayings were initially treated as a possible home-invasion robbery and the case went cold for years due to a lack of evidence.

In 2018 friends pressed police to reopen the investigation. Homicide Detective John Valdez later identified 28-year-old Christopher Joseph Gonzalez as a suspect. Witnesses reported seeing a red Dodge Challenger at the scene and investigators say two men, one of them Gonzalez, argued with the mother before the shooting. Gonzalez was arrested on October 2, 2020, in Baytown and faces capital murder charges; he is being held in the Chambers County jail awaiting trial.

Debbie had recently graduated from Molina High School and was remembered as sweet, kind, and intelligent. Does anyone in Dallas remember seeing a red Dodge Challenger near Debbie’s home on April 7, 2014?
