‘Iceman Oetzi’ lived for a while after arrow wound

My theory is that he took cover from his Italian pursuers(he was fleeing back home over the pass to Switzerland from a raid) He was bleeding out from the arrow wound in his back, but they found him and finished him off with a blow to the head.
“Taka that, you woman stealing Switzer!”
He had obviously pissed off some lowland dudes pretty bad for them to chase him that far up the mountain.
:’) They found no sausage casing neolithic condoms on the body, so you may be onto something. ;’)
That was just over three years ago though.
