Reigning Mafia boss of bosses Salvatore Maranzano was shot and stabbed to death in his Park Avenue, Manhattan, office. The assassins, sent by underworld bosses who had been targeted by Maranzano, posed as government agents to gain entry to the offices. Decades later, Joseph Valachi became one of several "inside" sources who provided background information on the killing.
|New York Times|
In late summer of 1931, Maranzano expected a raid from government agents. Fearing arrests on gun charges, he instructed his guards not to bring weapons to his office, the Eagle Building Corporation on the ninth floor of the New York Central Building, 230 Park Avenue.
Valachi was upset by the order. He told his associate Buster, "I don't like this. They are trying to get us used to come up here without any guns. I ain't going to come around here any more... You better talk to that old man and make him understand..." .
About twelve days later, on September 9, Valachi was called to Maranzano's home, 2706 Avenue J in Brooklyn. At that time, the boss of bosses revealed that he was planning a new war to eliminate those he viewed as his rivals. .
"Joe, I can't get along with those two guys," Maranzano said. Valachi understood that his boss was referring to "Charlie Lucky" Luciano and Vito Genovese, who recently assumed control of the large crime family previously run by Masseria. Maranzano revealed that there were others he felt needed to be eliminated, including Al Capone, Frank Costello, Guarino "Willie Moore" Moretti, Giuseppe "Joe Adonis" Doto, Vincent Mangano, Ciro Terranova, Arthur "Dutch Schultz" Flegenheimer.
Maranzano assured Valachi that all soon would be settled.
Overnight, Valachi wondered about the status of regional Mafia big shots Maranzano had not mentioned as targets of the intended new war. He later recalled, "I started to think that he did not mention Tom Gagliano, Frank Scalise, Don Steve from Newark, so I was wondering if those guys were in on it." 
The next day, September 10, Valachi prepared to meet with Maranzano as planned, but men higher in the organization called him away and kept him occupied until early the next morning. Valachi returned to his apartment at 108th Street and Second Avenue. Only then did he glance at the daily newspaper and learn that "they killed the old man."
The paper also reported that Vincenzo "Jimmy Marino" Lepore, a Maranzano ally in the Bronx, had been murdered at a barber shop, 2400 Arthur Avenue.
It occurred to Valachi that top Maranzano men had been "in on this" and worked to keep him away from the boss while the assassination was carried out. 
Days later, Valachi was summoned to a meeting with Tom Gagliano. The assassination of Maranzano was explained to him: "They told me the old man went crazy... and he wanted to start another war," Valachi recalled. "I knew they were right but I did not say anything." 
At a subsequent meeting with fellow Mafiosi, Valachi was given a story of the assassination. Girolamo "Bobby Doyle" Santuccio, who was taken into custody as a witness to the killing, told him, "...It was the Jews that came up at the office and they showed phony badges and they said that they were cops... There was about fifteen guys in the office at the time that they came up."
Maranzano escorted two of the visitors into his private office. Santuccio continued, "We heard a shot and everyone ran out of the office and, at the same time, the two guys came out and told us to beat it as they ran out. I went into the other room and I got on my knees and I lift his head and I saw that besides the shot they had cut his throat... I didn't care if I got pinched as I was disgusted, and I figure that even if I did run I won't know where to go."
