But authorities say it doesn't appear that the deaths are the result of foul play.
The bodies of a 57-year-old woman and 66-year-old man were found Saturday in a home in Middletown, Bucks County. Police Lt. Steve Forman tells Philly.com that the two appeared to have been dead for several days.
He says officials from the coroner's department will begin examining the bodies on Sunday and will look for signs of carbon monoxide in their blood.
The names of the deceased have not been released.
Authorities say the investigation is ongoing.
