One of the Black Mafia's most brutal, inexplicable crimes was 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 brutal that W.E.B. Griffin wrote a novel based on it, "The Witness," and Philadelphia Police Commissioner Frank Rizzo was quoted as saying that the DuBrow crime was "the most vicious crime I have ever come across.
