Trương Văn Cam, known by the sobriquet Năm Cam (April 22, 1947 – June 3, 2004) was a notorious Vietnamese mobster who is often called the "Godfather" of Vietnam. Known for building and running a criminal enterprise revolving around gambling dens, hotels, racketeering, extortion, loan sharking and restaurants that fronted for brothels, during his heyday, Năm Cam was considered one of the most powerful mob bosses in Vietnam, and was said to have attained influence that even extended into the ranks of Vietnam's Communist Party which he used to his advantage by bribing law enforcement and government officials to protect his lucrative enterprise and cover up his murders of other criminal rivals in Saigon that challenged his reign. In fact, his connection and ties with the Vietnam's Communist Party was so tight that during his trial, 153 other people that were tried with him were high-ranking officers of the Communist Party.
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 port city of Haiphong, Dung Hà who was considered 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. Năm Cam's first brush with the law came when he was just 15 years old for stabbing a man to death in a fight; he subsequently served two years in prison before joining the South Vietnamese army in 1966. As a youth, he was infamous around the local area for his brutal machete fights and for his slick ways of avoiding the police. During his early years as a youth in Saigon, Năm Cam was a follower of the most infamous mob leader in Saigon during the 60s, Đại Cathay, who was considered to be the top or the number 1 of the "Four Great Kings" of Saigon at the time. It was during his time as a member of Cathay's mob that Năm Cam would later learn from Cathay how to run and organize a casino in order to make great profits from it, a method that he would later utilize during his reign of Saigon during the 90s. Later, Đại Cathay and Bảy Sy, who was Năm Cam's brother-in-law were arrested as a result of South Vietnam's government campaign against crime in August 1966. Later, Bảy Sy was released and soon opened a casino, where Năm Cam and Nguyễn Văn Nhã helped out to run the casino. During this time, Năm Cam, under the guidance of Bảy Sy planned to kill Tài chém, a notorious gangster in the first district of Saigon, but the plan failed and resulted in Năm Cam being chased by Tài chém's gang brothers. After that, Hiếu Trọc saved young Năm Cam's life and put him into the position of military logistics staff of the 313th Company of the Armed Forces in the South Vietnamese army. After that, Năm Cam became a swimmer of the Military Office of the Armed Forces for the army.
Due to his gambling business, Năm Cam was able to amass substantial wealth for himself. In 1994, he was arrested and convicted for his criminal dealings, but was released early in May 1995 after an intervention by Trần Mai Hạnh, director of Radio the Voice of Vietnam.
On June 4, 2003, Năm Cam was convicted for ordering the assassination of Dung Hà and bribing state officials to protect his criminal network and was sentenced to death by the court. However, it was not until the police were able to collect all of the evidence, documents and secure the testimonies from Nguyễn Tuấn Hải, Nguyễn Việt Hưng, Nguyễn Xuân Trường that Trương Văn Cam finally admitted to all of his offenses in public.
