Mary Matsumoto, 72, of San Pedro, Los Angeles, was found dead on January 14, 2015, after her daughter requested a welfare check when she hadn’t heard from her for several days. Police discovered Mary in her bedroom with three gunshot wounds to the head; coroner’s records indicated she had been deceased at least a day before being found.

Officers found her husband, George Matsumoto, at the scene and unresponsive. The investigation focused on him and he was arrested and charged with murder.

If anyone knew Mary or had information about the days before January 14, 2015, please come forward with what you remember.
