NILES, Mich. (AP) -- Police are investigating the deaths of an 81-year-old man and his 55-year-old daughter after their bodies were found inside a cold southwestern Michigan home.
Police went to the Niles home Wednesday afternoon when a neighbor reported not seeing the residents and snow piled on a vehicle in the driveway.
Autopsies on the bodies of Albert Bivins and Patricia Bivins did not determine a cause and time of their deaths.
Results of lab tests are expected in the coming weeks.
Police say gas and electricity were functioning, but the temperature inside the home was below 32 degrees Fahrenheit (0 degrees Celsius).
Foul play is not suspected.
Niles is southwest of Grand Rapids and just north of the state line with Indiana.
