Aerial views of two mass graves in Alsace, FranceF. Chenal; P. Lefranc
I’m pretty sure the guy with the cracked skull went by Psycho, but his real name was Francis.
What is highly unusual about this find is the perpetrators (winners) went to all the trouble to bury the victims.
Most biblical massacres talk about leaving the victims to be consumed by wild beasts and birds of prey.
I’m not sure about the victims, but I think that the perpetrators might have been a member of either the Soprano or Corleone clans, and that the victims owed a bunch of sea shells that they couldn’t repay.
Now you’re talkin’

"Just not HIS arms and legs. Is that right?"
They pieced together the identities of the massacre victims? So what were their names?
Pretty easy to figure out which grave holds the dead of the winning side, and which has the bodies of the prisoners captured from the losing side.
