A neighbor’s call to police after noticing blood dripping from the ceiling of a South Florida apartment led to a grim discovery in the upstairs unit.

Margate police Lt. Joseph Galaska said 84-year-old Nicholas Mantzouranis killed his 66-year-old wife Sally Mantzouranis before turning the gun on himself.

Galaska said the tenant told a maintenance worker about the red substance seeping from the ceiling. Paramedics and police were called to the apartment to perform a wellness check. When no one answered the door, they removed it and found the bodies inside. A pistol was next to Nicholas Mantzouranis.

Police are continuing to investigate the case.
