Mary Jane Langdon, 66, of Houston, Texas, was found dead on November 15, 2023, in the parking lot of an abandoned bank on Wortham Boulevard. Her body had a gunshot wound to the head and evidence of mutilation. Funeral services were held at St. Stanislaus Kostka Catholic Church; she was remembered as a devoted grandmother and longtime Sunday school teacher in her parish.

Authorities arrested her 25-year-old grandson, Tyler Chase Langdon, at the scene and charged him with capital murder involving multiple victims. Investigators say he confessed to taking his grandmother to the bank parking lot, shooting her, and mutilating part of her body with a folding knife before fatally shooting his aunt, 42-year-old Janice C. James, at her home. A 12-year-old girl related to the victims called 911 and reported that Langdon had sexually assaulted her and killed her mother and grandmother. The child is receiving support and the family is trying to reunite with her.
