The JBM is estimated to have approximately 100 members and about 300 street-level associates. Its members drive expensive cars and still often wear gold jewelry and rings with the JBM initials encrusted in diamonds. JBM has sought to expand its drug trafficking profits by offering independent narcotic dealers membership in the JBM. The Pennsylvania Crime Commission documented two 1989 incidents in which the JBM targeted for death those dealers who turned down such offers. Like most local gangs, the JBM supplied sales and distribution services in the United States' fifth largest city to major international drug cartels, enabling these cartels to grow. The leader of the JBM, Aaron Jones, is currently on death row in Pennsylvania. Officials have reported that a relative of the late Russell Barnes who frequents Philadelphia and New York, is poised to take control, because of his close ties to Philadelphia's black mafia underworld and his ability to network and organize.
