Good question Dom...to my knowledge, he continues to deny ordering the hit. I have heard that he even has gone so far as to blame the Gambinos, as Naples did have some sort of ongoing dispute with them. However, all clues point toward Strollo. The hard thing to understand in that regard is that he would have had to obviously gotten permission from Mike Genovese for the hit, and its pretty widely accepted that Strollo was not on Genovese' Christmas card list. In fact, Genovese distrusted Strollo so much that he sent Henry Zatolla (as only a soldier) to Y-town to watch over Strollo (a capo).
