“The Vatican said the families of Federica, who died in 1840, and von Hohenlohe, who died in 1836, have been notified that their remains are missing.”
Ah, maybe grave robbers.
Maybe a little vatican necrophilia going on there...
I read that there was a new concrete seal on one of the doors. So I would suspect that if she had been placed in that tomb, in order to hide it all the other remains were removed, possibly along with those in the next tomb.
That said, having had connections with an historic cemetery, remains were often removed and record keeping was very poor. So this may be perfectly innocent. The only thing that worries me is the new concrete.
