The rotting bodies of a man and an elderly woman were discovered inside a Brooklyn apartment this week, cops said Tuesday. 

The 39-year-old man and 76-year-old woman were found in the living room of the third-floor unit on Quentin Road near West 5th Street in Gravesend when the NYPD and FDNY responded to a 911 call around 6:50 p.m. Monday, cops said. 

Both bodies were badly decomposed.

It was unclear how long they had been there.

The relationship between the two people – and the circumstances surrounding their death – were not immediately known.

 Their names were not released, pending family notification.

The city medical examiner’s office will make an official ruling on the cause of death, police said.
