As discussed in Black Brothers, Inc., Raymond "Long John" Martorano formed a partnership with imprisoned Black Mafia heavyweights Lonnie Dawson and Nudie Mims to run a massive heroin distribution network in the early 1980s. Martorano was housed in Philadelphia's Detention Center with Dawson, who was the institution's most influential prisoner. Dawson, who had corrupted guards with various goods and services, met regularly with Afghan heroin smugglers and dictated the drug traffic from inside the prison walls for several of the city's most consequential territories. Martorano's son, George ("Cowboy"), was an intermediary between Martorano/Dawson and Nudie Mims, who was running a similar network out of Graterford Prison, where he was serving a life sentence for murder. On FBI wiretaps, Mims and Dawson were recorded saying they could sell $400,000 worth of heroin per month.
