Preet Bharara, United States Attorney for the Southern District of New York, announced that Bing Yi Chen, a/k/a "Ah Ngai," the lieutenant of a Chinese organized crime group, was sentenced today to 35 years in prison for his participation in a murder of two individuals in Toronto, Canada, on July 20, 1994, in connection with his group's heroin trafficking activities. Chen was convicted of two counts of murder by a jury on October 23, 2007. Frank Ma, or "dai lo," of the criminal enterprise, pleaded guilty to the charges four days before trial began on September 20, 2007, and has yet to be sentenced.
From 1991 through 1996, Ma, Chen, and their associates were engaged in the importation of millions of dollars worth of heroin from Asia into the United States for distribution in New York City.
On July 20, 1994, two members of Ma's hit team shot their way into a business office where the
intended victim was supposed to be, and killed Kwan Kin Ming and Yip Pak Yin, two office workers.
The convictions of Ma, 55, and Chen, 42, were the result of ten years of investigative work into
the MA organization, which has, to date, resulted in 13 convictions.(Source: American
