Brokeback Mountain

¡ spoilers ! 

so everyone that have watched brokeback knows that jack twist died, the wife said that he died because of an explosion, but there's another theory

as jack goes to the bar after the rodeo he sees the bull clown that distracts the bull's so he comes sit next to him, tries to pay him beer, however as they have a little chat jack smiles at the rodeo clown, the rodeo clown looks change, into something like disbelieve and disgust for a second, then he pays and leaves, its a small theory but it could be that those guys at the pool table decided to kill jack twist because they saw his interest in guys??? or maybe they connected the wife, i dont believe it was the bar man because he was pretty chill, neither the men in mexico, so it couldnt be anyone else exept those guys and his wife, its still a mistery for me XD
