Centerport, PA – Authorities say an eastern Pennsylvania woman and her dog died of accidental carbon monoxide poisoning from a blocked furnace exhaust that sent smoke into the basement.

The Reading Eagle reported Thursday that 78-year-old Lucille Ohlinger was found by firefighters in a recliner, with her small dog on the floor nearby.

The coroner’s office says it’s thought Ohlinger died Monday, after she told a relative in a phone call she felt sick to her stomach and that her dog was acting strangely.

A nephew went to the Centerport home on Wednesday and realized there was a strong odor of exhaust and black soot on the basement doors. He called 911.

Centerport is about 15 miles north of Reading.
