Both. He was all the way up in the Alps and got shot up there. IDK if he died from the arrow wound or from exposure or a combination of both, but i doubt he would have died on that day if he would not have had the person who shot him on his trail. OFC it’s hard to reconstruct after all this time even when the remains are surprisingly well preserved by the ice.

Also i just looked this up, it was 5300 years ago, not 8000.
