How did frank nitti die?

Answer 1

In march of 1943 Nitti was indicted for extortion (Illinois hospitals and Hollywood studios) and was facing another prison sentence. (He previously did 18 months

along with Al Capone for income tax evasion). Having terminal cancer now, and

with clausterphobia, he wasn't about to allow himself to be imprisoned again,

and the night before he was to appear in front of a grand jury, he took his .32

caliber pisto; to a railway yard near where he lived, and witnessed by a couple

of railway workers, put the gun to his head and fired two rounds.
