actually accardo was a good boss,but the hit on giancana was sanctioned by the cia and carried out by trafficante jr. giancana had sought refuge in mexico,he said it was to retire but i have heard that operation cuba failing like it did was his reason,he knew that he was next on the list to go, he was shot in his basement kitchen while cooking sausages,5 times under the chin once in the back of the head.
