Officials are investigating the deaths of two 65-year-old women whose bodies were found today in a Roxborough home.

Police initially thought the women might have died from carbon monoxide poisoning, but late this afternoon they said the Medical Examiner's office indicated that the women died of natural causes.

Jeff Moran, a spokesman for the Medical Examiner, said autopsies are planned for tomorrow.

Police found nothing suspicious at the scene and said neither woman showed signs of trauma.
