Which former President's crypt was robbed and the body lost to history?

[Kaleva]

2. Learned last night that Abe and Mary Todd Lincoln were buried in a basement for awhile.

" Initially trying to dig a grave in the basement, they found that water seeped in wherever they dug, so they simply set the coffin on the ground and covered it with bits of lumber left over from the tomb's construction, disguising the coffin as a woodpile. Two years later, they managed to find a dry corner in another part of the tomb basement to bury the coffin under a few inches of dirt"
