Mafia also carried out the Dubrow Furniture Store robbery. On January 4, 1971, eight Black Mafia members robbed DuBrow's on South Street in Philadelphia. They entered the store one by one posing as customers. Once all were inside, they pulled guns on the twenty employees present and forced them to lie on the floor in the back of the store where they bound them with tape and electrical cord. Thirteen employees were beaten while two others were shot. A janitor who walked in on the robbery while doing his job was shot and killed. One employee was doused with gasoline and set on fire. After their vicious treatment of the employees, they looted the offices in the store and set more fires to destroy evidence of the robbery. The eight criminals fled the scene as soon as the fire alarm went off, purposefully trampling on one of the victim's bodies as they left. This crime was so notable that W.E.B.

Before Palmer's bodyguards could defend themselves, the mafia opened fire in the club, wounding 20 people. In addition to Palmer, three women and one of Palmer's bodyguards were killed. By far the most well-known act of crime that the Black Mafia carried out, the 1973 Hanafi Muslim massacre was what gained them national media attention. On January 18, 1973, the mafia murdered seven Sunni Muslims. Two adults and five children, aged 9 days to 10 years, were murdered. The adults and one child were shot while the other children were drowned. The intended target of this crime was Hamaas Abdul Khaalis for a letter he had written to the NOI members claiming that Elijah Muhammad was a false prophet and that certain members of Elijah Muhammad's NOI were merely
