Cerith snails missing, maybe dead, but how do I find them?

I added 4 cerith snails to my 55gal a few weeks ago. I drip acclimated them while floating the bag in my sump for 3 hours before adding them to the tank, and they started off looking healthy and eating. My tank has no shortage of things to eat. They basically buried themselves deep in the sand during the day, and then burst out at night to comb the bottoms of my LR (er, well, burst is a little too dynamic a word here I guess).
But as time went on, I saw fewer and fewer out at night (I can observe as late as from 11pm-2am or so), until now, where I can't seem to find any trace of them at any time, and haven't for two weeks now. I am assuming that they are dead at this point... the problem is, I can't find the bodies. I can't think of what would have killed all four so quickly, other than perhaps my substrate has nasty nutrient pockets that they went too deep into and gassed themselves.
Do these snails generally die under the sand? And if so, how the heck am I going to find their bodies to remove them (preferably before they rot and release more bad nutrients? I can't very well just stir up all my substrate, because that will release more trapped nutrients into my system, and if that is what killed the ceriths, I'll just hurt other things in my tank. But if they are dead, then I'd really like the shells to be out on the surface at least so that my hermits can use them.
I also wondered if my hermits could have killed them, but the fact that none of their shells are above the sand coupled with no hermits walking around in cerith shells seems to rule this possibility out.
Anyone have these snails in their system? Anyone experienced mysterious disappearances like this? Could they still be alive, and only briefly surfacing between 3am to 6am or so? That seems unlikely to me, and I don't see any evidence in the substrate of being moved around either.

They pretty much stay burrowed in my tank but they are out from time to time. It's possible the hermits ate them. My hermits eat mine and every couple of months I get a few more.

If yours are like mine, you can drop some pellet food to the bottom of the tank and they will appear like magic to consume it - if they're still alive.

I still think that if hermits ate them (which would be the best death, at least for the health of the tank) that the shells would be above ground. My hermits do need shells, which is partly why I'd like to recover these if the snails have died.
What sort of pellet food are you using though? My nassarius snails swarm over any goodies I add to the tank, but do cerith have a different taste/smell response for different food?

I've had them swarm both formula 1 and formula 2, Not aware of different responses to different foods - but this is all I feed that ever settles to the bottom in a concentration (if that makes sense).
