I say the Chicago guys. What they did to Action Jackson was insane. Then they carved up Leo Foreman like a fish for fun. There was the M&M murders where Chuck Nicoletti was eating a plate of spaghetti while eyeballs were being popped out. DeMeo chopped up bodies to hide the evidence. The Chicago guys chopped up bodies for laughs.
actually they liked leaving people in car trunks
or tossing people in ditches
They called it trunk music.
