What happens to the corpses?

Hey all! I'm running a few sessions of BitD shortly and I have a score idea where the PCs are tasked with retrieving an heirloom ring that somebody choked on. The ring is in the body, so the PCs have to find a way to extricate it. However, I'm confused about what happens to the physical bodies of the dead. I know the spirits within those bodies are purged by the Spirit Wardens at Bellwether Crematorium, but what about the actual physical corpse? My assumption is that something is done post-purge with the bodies (I've seen mention of graveyards and such in other BitD discussions), and I'd imagine Inspectors would require the bodies to perform their jobs. Is there a morgue? If the bodies are returned to the families post-purge that would hurt my idea, but maybe they're not (for fear of exorcism magic or something) and they're buried, burned, etc. somewhere? Has anyone delt with this in a sessions and if so, how did you manage it? Any thoughts welcome. Thanks!!
