I would guess it is here
The circumstances of death invite speculation that it was a woman-raiding party that at some point went very badly for the raiders. They did not have livestock yet. So maybe it was just a bunch of horny single guys from a village in the central valley who decided to find some women from a more populated area in the coast, only this time, the coast village they chose to raid from was ready for them and decided not to let them off with just a slap on the wrist.
Naw, they probably died from el Nino, or maybe white privilege. ;’)
