(June 2012) (Learn how and when to remove this template message) </Td> </Tr> <P> In 1971, Matthews invited major African - American and Hispanic drug traffickers throughout the country to attend a meeting in Atlanta . The DEA got wind of this and monitored who attended . It was a "Who's Who" of major drug traffickers, a testament to the respect Matthews commanded because of his vast drug empire . The topic of the meeting was how to import heroin without the Mafia . Those present decided to build stronger independent relationships with the Corsicans and possibly Cubans . In addition, they agreed to diversify their product to include cocaine, which was becoming available in massive quantities . </P> <P> This gathering of major drug traffickers throughout the United States is significant because it represented the changing nature of the drug business . Whereas, previously, the Italians controlled the importing and wholesaling of narcotics, therefore controlling who could and could not advance past them, now others were establishing their own pipelines . Before, the Mafia asserted behind - the - scenes control of the business while African - Americans sold and used the drugs in their cities; now the black dealers established connections and took control of their neighborhoods . This later evolved to include not just black people controlling the business, but also local gangs of black people eliminating out - of - town black suppliers trying to control their neighborhoods from a distance . </P> <P> Matthews learned this lesson the hard way in Philadelphia . In Atlantic City, the Philadelphia Black Mafia killed Tyrone "Mr. Millionaire" Palmer, Matthews' main dealer in Philadelphia, at a "Club Harlem" packed with 800 people . No one was prosecuted for the crime and none of the 799 potential witnesses came forward . Three of his top lieutenants in the city were murdered by the Black Mafia . </P>
