A Connecticut mansion bought cheaply at auction reportedly contained the decomposing bodies of members of the Marchion family, turning an apparent property bargain into a death investigation. The case matters because investigators are examining both the likely cause of death and the family’s past to establish how the deaths went undiscovered.

The supplied text identifies Sally Cash and Edward Marchion in connection with the property but provides no verified account of the deaths, timing, sale price or official findings. It also says the mystery has become darker as a probable cause and troubling background details emerged, but does not include enough information to specify them.
