Degenerate gambler, junkie, alcoholic and possible made guy who knew a lot the Outfits dark secrets, mixed with the fact that he had a traditional boss, Paul Ricca, who in turn was a immigrant and was also tired of all the publicity that was already brought by his predecessor Capone and his associates such as McGurn. Dont get me wrong since there were also other guys whose names were constantly in the newspapers because of their deep involvement with the previous administration, such as Maddox and Capezio, but these guys still made a lot of money and continued killing important targets for the organization.

On the other hand, there is another story in which allegedly MCGurn "stepped on the toes" of some bosses who were already involved in the dope trade and thats why he was allegedly killed for. This story somehow fits with the info regarding Henney allegedly introducing McGurn to the dope trade, a deal which was probably made only between the two and later Heeney probably "sold out" McGurn. Besides being non-Italians, both Heeney and Maddox were quite respected and probably held higher stature than some of the made guys.
