Wai Keung Tsang

Wai Keung Tsang, a 43-year-old part-time unlicensed cab driver, was killed on April 11, 2007, in San Francisco, California. Tsang was working as a driver at the time of his death when he was shot at around 11:25 PM on Santiago Street near 30th Avenue in the Sunset District. After being shot, Tsang attempted to continue driving but ultimately crashed into the garage of a home at Santiago and 29th Avenue, where he struck a water heater that ignited a fire. Authorities believe he was already deceased by the time the blaze began.

The circumstances of the shooting pointed to a possible attempted robbery or a dispute with a customer. Although Tsang still had money on him when he was found, the motive for the crime remained unclear, and no witnesses came forward. At the time of his death, Tsang was working within an informal network of unlicensed "pirate" cab drivers, a group that often operated without the necessary permits and licenses due to the difficulties in acquiring one of the limited medallions for official taxi services in San Francisco.

Tsang had moved to San Francisco from Hong Kong in 1990 and initially worked as a waiter before switching to cab driving two years before his death. His brother, Peter Tsang, described Wai Keung as someone who loved driving and Chinese music but also faced financial difficulties, including a lawsuit from Toyota for unpaid debts. Tsang’s death remains unsolved, adding to the list of cold cases in San Francisco. The San Francisco Police Department continues to offer rewards for information that could lead to an arrest and prosecution in such cases.
