Asau Johnny Tran was 38 when he was killed in a sustained, targeted shooting outside the Pot of Gold restaurant at Beverley and Dundas Street West in downtown Toronto in the early morning of August 16, 1991. Police arrived around 3:20 a.m.; Tran was found with multiple gunshot wounds, rushed to hospital and died shortly after. Two other men at the scene, Shun-Keung Pun (also known as Tony Pun) and Tin Wah Lui, were also shot, taken to hospital and later died, turning this into a triple homicide at 393 Dundas Street West.

Published accounts describe Tran as a former leader of a large criminal organization linked to protection rackets and extortion, and note a 1986 investigation that involved Tran and 27 others facing a combined 88 charges. About a week before the shooting he gave a television interview saying he doubted he would live to 40 and that a rival group might kill him. Investigators have at various times considered motives including unpaid gambling or gaming debts and gang turf struggles, but no suspect has been publicly identified and the police list the killings as cold.

Did anyone who knew Tran or the other victims have observations about their movements in the days before August 16, 1991?
