For 15 years, Năm Cam reigned as the Godfather of Saigon. His downfall however came during a gang feud with another notorious female gangster from the northern city of Haiphong, Dung Hà who was considered as one of the two great powers of the Vietnamese underworld alongside Năm Cam. Coming to the South, Dung Hà attempted to build her own gang in Saigon, and often came into conflict with Văn Cam. After a series of confrontations and standoffs between Dung Hà's group and Năm Cam's mob, Cam ordered the murder of Dung Hà. Authorities later arrested him alongside several members of his mob and cooperating Communist Party officers, leading to a massive public trial totaling 155 defendants, making it the largest criminal trial in the country at the time. Năm Cam and four of his members were sentenced to death, and Năm Cam was executed on June 3, 2004.
