On April 7, 2014, Ammy Soumphonphakdy, a 50-year-old Laotian woman, was shot in the head and killed execution-style in her Dallas home on Western Park Drive. Her 18-year-old daughter, Debbie Thammavongsa, was killed in the same attack; a third unidentified man was also shot but survived. Witnesses reported two men in their 20s arguing with Soumphonphakdy shortly before the shooters fled in a red Dodge Challenger.

The case went cold for several years due to lack of evidence, but friends of the family pushed for a reopening in 2018. Detective John Valdez later focused the investigation on Christopher Joseph Gonzalez, who was arrested by the U.S. Marshals North Texas Fugitive Task Force on October 2, 2020, and charged with capital murder.

Does anyone have information about the people who argued with Ammy that day or who saw a red Dodge Challenger in the neighborhood?
