Morbid question

[amie-de-rimbaud.livejournal.com]

I've been wondering:  what happened to all those bodies sans têtes? I assume--I'm sure I've read--about mass graves, but does anyone know where they are exactly? Down in the catacombs of Paris (which I've still not visited, sadly) would be my guess, but I didn't know for sure. I have a feeling this is common knowledge, so I apologize for asking a possibly silly question.

Also, was anything special done with the bodies of remarkable victims--Louis, or the Girondins--to ensure that followers didn't try to memorialize them in any way, or--creepiness alert--steal body parts to save as relics? Did they drive a stake through Maxime's heart to make sure he wouldn't rise from the dead? (I'm kidding) But I'd love to hear any fantastic stories of this nature.
