FOUND - Specific preseries fic: boys buried alive, John can rescue one

[nightowlv]

I'm looking for a fic I read a long time ago. I can't remember the title or the author, and I have not been able to find it myself. I've looked and looked, to no avail. It's a preseries story, and this is what I remember: Someone (it might be another hunter, but I can't remember for sure) buries both boys alive, and John has only enough time to rescue one. They're buried next to each other, and I think he's told where each is buried. If I remember correctly, he rescues Sam first, and then somehow gets Dean out, too.

If anyone recognizes this story, please let me know. I would greatly appreciate your help! Thank you!
