"In 1980, the longtime Don of the Philadelphia crime family, Angelo "Gentle Don" Bruno, was shot and killed on March 12. This resulted in a huge power vacuum between prominent Bruno members Philip Testa and Nicodemo Scarfo, both fighting for the total control of the Bruno crime family. Accetturo and Taccetta, on the other hand, used their situation to establish a new foothold in Philadelphia, as a part of the Jersey Crew, with illegal gambling and loansharking operations. Unfortunately, because of the bad relations between the two factions in Philadelphia's crime family, as well as both Taccetta and Accetturo taking advantage of the situation, the relationship between Philadelphia and the New York Families, especially the Luccheses, eventually turned worse after the murder of Angelo Bruno, which led to all cooperation between the families being completely terminated. It was around this time that prominent Bruno member Giacomo "Jackie" DiNorscio, and many others, defected to the New Jersey faction of the Lucchese crime family to make more profit and to avoid being killed."
Does anyone have more details on how they capitalized in this power vacuum? Or any details on how Jackie DiNorscio switched sides?
