The bodies of a 57-year-old woman and 66-year-old man were found by police Saturday afternoon in a home near St. Mary's Medical Center in Bucks County, officials said.

Middletown Township Police Lt. Steve Forman, who did not identify the man and woman, said in an interview that there was no sign of foul play.

The bodies were found in the house on the 1300 block of Langhorne Newtown Road by police responding to a request by a friend who had been unable to contact the woman, who owns the home, Forman said. The two appeared to have been deceased for several days when officers arrived after receiving the call at 1:41 p.m., he said.

Coroner's officials are expected to begin examining the bodies Sunday and will look for signs of carbon monoxide in their blood, Forman said. While fire department officials did not detect high carbon monoxide levels in the home, the house had "multiple different types of heating systems" and its door had been open for a while when they tested for the gas, he said.
