Matthew Madonna (b. 1935) is a New York City mafioso and former heroin trafficker who had supplied Leroy "Nicky" Barnes, among others, with dope. Madonna met Barnes in 1959, while the two were serving time in Green Haven Correctional Facility in upstate New York. At the time, Madonna was a Lucchese crime family associate. Madonna supplied Barnes with heroin (about 20 to 30 kilograms per month) for over five years, until Madonna was busted in 1975. Wikipedia
