On September 29, 2007, 66-year-old Kam Yan was fatally shot while walking with a family member in San Francisco’s Japantown. An unknown assailant approached and opened fire without warning; authorities found no clear link between Yan and the shooter and the motive remains unknown.

The killing was one of several seemingly random shootings in San Francisco that year. No suspect has been conclusively identified or charged in Yan’s death.
