The two brothers had often argued, and earlier in the decade, studio employees claimed they saw Harry chase Jack through the studio with a lead pipe, shouting, "I'll get you for this, you son of a bitch" and threatening to kill him.
De to brødre havde ofte skændtes, og tidligere i årtiet hævdede ansatte i studiet, at de havde set Harry jage Jack gennem studiet med et blårør mens han råbte "Jeg vil få ram på for dette, din bastardsøn" og truede med at dræbe ham.
