How did jack twist die in brokeback mountain?

 
I am also left with a huge question mark about the nature of Jack’s death. Jack died in the way Ennis always feared. Or did he? We don’t see Jack die; we see Ennis visualizing Jack’s death while Lureen tells a different story.

Granted, Lureen’s stiff, formulaic delivery of the story is meant to tell us she is lying. But is that Lureen, or how Ennis hears Lureen? Did Jack die in a gay-bashing, or does Ennis imagine it because he is still so profoundly trapped in his closet? I don’t think the movie intends us to be sure. Indeed, the original story seems to leave the same question open. Ennis is sure that Jack died in a gay bashing for two reasons; first, because it is the fear that drives him, and second because he learns that Jack has had relationships with other men, putting him at greater risk.

No mystery it was a queer bashing!
