Bodies of a man and woman were found inside a home on Cedar Drive in Southington on Wednesday afternoon and police said the medical examiner determined that the woman died of natural causes.
Police have not yet made an official ruling on the man's death and said further forensic studies are required.
Officers went to 27 Cedar Drive at 2:57 p.m. for a welfare check when a delivery man called and said he saw several newspapers accumulating outside of the home and no one answered the door.
Once police were inside, they found the bodies.
Police said there are no indications of foul play, no indication that either individual was the victim of a homicide and no evidence that a crime occurred inside the residence.
The names of these individuals will not be released until an official identification is made by the Office of the Chief Medical Examiner.
Southington firefighters tested the air inside the home, but did not detect carbon monoxide or other hazardous gases, according to police.
