Dead in the Snow

[iago]

Detective Jones and his men searched the frozen tundra for escaped convict Al.  just as they were about to quit, one of his men spotted a body.  Al was found lying dead in the snow.  There were no tracks leading to or from his body.  His death was partially caused by an unopened pack on his back.  Al did not die of thirst, hunger, or cold.  What was in Al's pack that led to his death?

He jumped out of a plane and his parachute failed?

If you're all going to solve these so goddamn fast, I'm going to stop posting them! :)

Or doing them early/late, hah!

He was skydiving, his chute didn't open properly.

Or maybe he could have drowned in midair, that happened on Monk once when Mr. Monk went to Mexico. :)

Edit: Damn Sidoh and him posting 42 seconds sooner. Damn me and my rewording of response, I couldn't decide if I should use 'shute' or 'parachute' or 'properly' or 'correctly.'
