Not just in Hawaii 5-0. Any mafia movie you watch, the hit men always come from Detroit. Somebody must know something. Sometimes they are vague about it, and they say: We’re bringing in some guys from the east, but you know they mean Detroit!
In the Maltese Falcon (1941) the hitman (Wilmer played by Elisha Cook Jr) was from Detroit.
You want to read about a real bad killer, check our Roy DeMeo, a mafia killer suspected of over 200 deaths...many of them quite gruesome.
I think his crew rivaled Murder, inc.’s murders.
