Summary based on the NamUs case record (MP9383) and 11 other sources

Pauline Diaz, a 63-year-old woman, was last seen on December 7, 2010, after finishing her shift at an H-E-B grocery store in San Antonio, Texas. She was supposed to visit her estranged husband, Pedro Ruiz, to pick up a lawnmower. Pauline's white Toyota Tacoma was found abandoned days later near Ruiz's home, but she was never located. Investigators have considered Ruiz a person of interest due to suspicious behavior following her disappearance, though no charges have been filed. Pauline’s case remains unsolved, and her family continues to seek answers.
