Authorities have confirmed that as the new owners began work on the property, they stumbled upon Iffly's remains when searching for a leak in the roof. Prosecutor Olivier Glady stated that a rope, suggesting possible suicide, was found hanging in the attic where the body was concealed in a hidden cubbyhole. Aloïs Iffly had been reported missing after he disappeared in 2009, and his wife lived in the home until her own death in 2020, after which the property was sold in 2023.

The shocking discovery has prompted an investigation into the cause of death, with the remains sent to Strasbourg for autopsy to finally unravel the mystery behind Iffly's extended absence. Extensive searches and investigations conducted over the years yielded no trace of him, leaving family and authorities in the dark until this recent revelation. The case has now drawn renewed interest, as it holds the potential to provide closure for a mystery that has lingered for over a decade and a half.
