*Corrected broken link* Can You Help? 25th Anniversary of Cold Case Homicide

Our message earlier this morning about this case had a broken link to the video.  Our apologies.  Here's the same message again, but with a working hyperlink this time:

*****

Twenty-five years ago tonight, on June 10, 2001, Maria Hsiao was shot and killed outside of a downtown Palo Alto nightclub. Her case remains unsolved, and we need your help to solve it.

On the anniversary of Maria's death, please watch this video on our website explaining what happened and the impact this crime has had on many people: https://www.paloalto.gov/News-Articles/Police-Department/Can-You-Help-25th-Anniversary-of-Cold-Case-Homicide, and then please share it with your friends. The more widely it is seen, the more chances exist that someone will come forward with a tip that may break the case. Even someone with second- or third-hand information about what happened may hold the missing piece of the puzzle that helps us to crack this case, solve a mystery, and bring justice for Maria, her family and her friends.

Anyone with information about this incident is asked to call our 24-hour dispatch center at (650) 329-2413.  Anonymous tips can be sent via text message by texting the keyword PAPD and the tip to 847411, or submitted using the "Palo Alto PD Tips" app, which is available via the App Store or Google Play.

Thank you for helping us, and thank you for keeping Maria and her family in your thoughts today. And for more information on the foundation her family set up in Maria's memory, visit the Ria Foundation's Instagram account here: https://www.instagram.com/riafoundation/ #JusticeForRia
