Who killed Maria Hsiao? Witnesses urged to come forward in 23-year-old Palo Alto case

It’s been 23 years to the day since Maria Hsiao was shot and killed outside a Palo Alto nightclub, but her family and investigators hold out hope that someone somewhere will come forward with information needed to finally close the case.

On the night of June 10, 2001, Hsiao was out celebrating her 21st birthday with family and friends. She was shot in the head while standing in a crowd outside the Q Cafe, a former pool hall on Alma Street that is now Patagonia Palo Alto.
