The parent company of more than 400 cemeteries nationwide has been hit with a potential class action stemming from its alleged practice of interring multiple bodies in the same graves.

The lawsuit filed Monday against Service Corporation International (SCI) in the Philadelphia Court of Common Pleas alleged that plaintiff Maya Devinskaya’s daughter was buried in a grave already occupied by another family’s deceased relative. The complaint alleged Devinskaya was the victim of SCI’s practice of “overselling” graves in which bodies overlapped.
