The Italian underworld within Detroit had experienced its own power struggles in the mid-to-late 1910s and with the death of top Detroit Mafia Boss, Sal Catalanotte in early 1930, the Detroit Mafia was once again experiencing unrest, rivalry and conflict. The truce and alliance that Catalanotte had created and Milazzo had assisted with for the last few years was now coming unhinged and one of the most volatile conflicts that had already seen some violence was between the East Side and West Side Mobs. West Side Mob leader Chet La Mare had sent word to East Side Mob leader
Angelo Meli that he wanted a sitdown to discuss Mafia affairs and possibly end the feud, but Meli was no fool and he knew that it was not safe to meet with the treacherous La Mare. Meli figured that because Gaspar Milazzo was such a highly respected figure within the Detroit Mafia and known for his mediation skills he could send Milazzo in his place and La Mare would not take it as an insult as he would understand how Milazzo would be seen as the only man who could mediate this dispute so Meli asked Milazzo to go to the meeting in his place and Milazzo accepted. What was not known to Milazzo and Meli was that powerful New York Mafia Boss
Joe Masseria had begun to support Chet La Mare in his bid to take over the Detroit Mafia, which was something that would not please Milazzo who was a close associate of Angelo Meli and his two right-hand men, Joe Zerilli and Bill Tocco. It's not known for certain whether or not Milazzo knew about Masseria's support of La Mare. Milazzo accepted Meli's proposal to have him attend the "sit-down" meeting with La Mare as Meli believed that La Mare wouldn't dare kill a Mafia Boss with Milazzo's respect and support knowing it was instantly start a war. The meeting was set for the
Vernor Highway Fish Market in Detroit and on May 31, 1930, Gaspar "The Peacemaker" Milazzo and his right-hand man and driver,
Sam "Sasa" Parrino, attended the meeting in place of
Angelo Meli and his associates. Milazzo and Parrino were seated and while awaiting La Mare or his representatives they began their lunch. Without comment two gunmen leaped out and unleashed a barrage of shotgun blasts that hit Milazzo in the head and killed him instantly, Parrino was hit in the chest, abdomen and arm and soon died. Gaspar Milazzo died at the age of 43. He left behind his wife, Rosaria, and four children. ==Aftermath==
