John "Ray" Enright, the federal narcotics agent who arrested Vito Genovese in 1958 for trafficking heroin out of his gay bars in Greenwich Village and the Lower East Side, has died at 85 in Colorado as reported by Kieran Nicholson for The Denver Post: "at that time, Enright was the head of a federal drug task force that dogged an infamous meeting of Mafia bosses from around the country." Enright later became the director of the Colorado Bureau of Investigation from 1977 to 1984.
Genovese was convicted for his drug dealing, and sentenced to 15 years in the Atlanta Federal Penitentiary. He died in 1969. At the time of his death the feds were investigating him for allegedly bribing a U.S. Congressman.
The FBI files are light on Genovese because during the 1950s Director J. Edgar Hoover was either ignorant of or beholden to the Mafia, and in light of Hoover's abdication of duty -- if not treason against the country -- the Bureau of Narcotics within the Treasury Department was assigned to take down LCN.
