The decomposed bodies of a man and a woman were discovered Thursday evening in a fourth-floor apartment in the Neos Kosmos district of Athens, prompting a full-scale police investigation.
Authorities identified the man as 74 years old. At the scene, officers recovered two shell casings and a shotgun, raising questions about the circumstances of the deaths.
The woman had a chest wound, while the man appeared to have suffered a head injury.
Police have not ruled out any possibilities, including murder, femicide, or the involvement of a third party.
One theory under investigation is that the man may have killed the woman before taking his own life.
A neighbor reported hearing two gunshots around 5 a.m. on either Monday or Tuesday, a detail that may help pinpoint the time of death.
The discovery was triggered by a strong odor, which led residents to alert the building manager, who then contacted authorities.
