CLEARWATER, Fla. -

The manager of U-Stor Self Storage heard a bizarre tale when he notified a woman that the items stored in Unit B8 would be auctioned because she'd fallen behind on rent.

Manager Kevin McKeon says the woman told him her grandmother's body was in a coffin inside the storage unit. Clearwater police on Thursday found skeletal remains inside a blue coffin stored there.

The Tampa Bay Times reports that the woman told police her mother, as she was on her deathbed last year, informed her about the situation.

Police recovered death certificates for the grandmother, who died in 1995.

Medical examiners told police the grandmother's body had been properly processed for burial but it was unclear why the casket was in the storage unit.

Police say they don't believe she died under suspicious circumstances.

It's not known where the body of the woman's mother is located.
