The neighbours next door where I grew up were not present when they should have been. Final report was they died within hours of each other from natural causes.

They were somewhat a miserable couple. It was rumoured they sold their land for the ford factory of Canada to build their facility on.

My mother kept tabs on older aquaintences and friends that lived alone. Surprisingly enough she had two die over the years. She had the police break in to the two residences.
