Dudley Yasuda, a 43-year-old psychology professor at San Francisco City College, was shot to death on April 12, 1982. Yasuda, a faculty member since 1967 and known for engaging lectures and mentoring students, was meeting with eight students in his office when an unidentified gunman entered, fired multiple shots, and fled. Yasuda was struck in the chest and abdomen and died at San Francisco General Hospital about an hour later.

Investigators learned that Yasuda had received warnings about potential threats a week before the killing when an unidentified psychologist told the college that one of his patients might try to harm Yasuda. Police believed the suspect might be a former student, but no immediate arrests were made. Homicide inspector Marvin Dean and Police Sgt. Mike Pera led interviews of the students present and followed multiple leads as they tried to identify the shooter.

The motive remains unclear and the assailant’s identity was not established immediately after the shooting. Did anyone who knew Yasuda, his former students, or colleagues have information that could help resolve who entered his office that day?
