So like Iām absolutely not a historian or anthropologist at all. But I really like stories and if this was a fictional story then Iāve got an idea as to who his murderer could be.
Ćtzi was a wealthy man who was travelling. Perhaps he was simply an explorer, using his wealth to see the world. Perhaps he was visiting family, or returning from a trip. But either way way heās a wealthy man, probably a weapon smith, forging tools from copper and wood for others to use. But regardless, he is travelling through the mountains.
Itās a long journey, and while Ćtzi can probably hunt for himself or has non perishable or preserved food on his person, heās been getting sick a lot. Perhaps heās not used to the cold, or brought some disease with him on his journey, but heās now presented with a problem: if he gets sick again, he may not make it through the mountains. If he becomes incapacitated from his disease, the odds of running out of food and starving or freezing become too high for him to bear. Ćtzi does not want to die. But he fears he cannot survive on his own.
Thankfully, people live in these mountains, and a travelling family happens upon him in the snow. They greet him kindly and he greets them in turn, and they camp together for the night, sharing a fire and eating together. Thereās a mother and a father and a few children, scarred by sickness and fights and the world, but all still breathing. Before he goes to sleep, Ćtzi glimpses medicine among their supplies. Medicine for wounds and for illness. And Ćtzi does not want to die.
He thinks about it as he falls asleep, itās the first think he remembers when he wakes up, he stares it down as he eats breakfast, as he barely notices when the eldest daughter leaves to hunt and to scout the area. It consumes him. Ćtzi does not want to die here.
They were kind to him, so heās courteous enough to ask for it first. Of course they say no. There are more of them and he is a stranger. They will not give him something so vital. So he kills them. Their weapons are fine for hunting, but he is an excellent weapon smith and his are better. There are more of them, but the children are young, and the parents are his first targets. Ćtzi leaves the ashes of the fire and the corpses of kind strangers with a basket of medicine and a feeling of relief.
His relief clears his mind of all worries. Swallowed by the knowledge that his odds of survival are so high that it would take a freak mishap to kill him now. But he is set. The family is all dead so they cannot follow him. And even if there were a surviving family, there were not any long range weapons left at the camp, which a potential revenge-seeker would need in order to kill him, for he would surely win any close quarters fight, and would hear an assailant crunching through the snow before they reached him. These are thoughts he might have had, if he wasnāt basking so much in his safety. And perhaps, if he had entertained these thoughts more, he would have realized that there was someone left who fit all the criteria of his possible murderer.
The eldest daughter is an excellent shot. He is dead by the time she reaches him. Her familyās blood is still on his weapons, and it almost makes her vomit. She canāt take them. She also canāt bring herself to take back the medicine that killed her family. Or maybe sheās just in too much shock from the death of her family. Maybe sheās doesnāt know if she wants to live anymore. She snaps off the shaft of her arrow. He doesnāt get to take anything else from her.
She wanders off into the snow, leaving as a murdererās murderer.
