76-year-old woman found outside Ohio nursing home died of hypothermia

PANDORA, Ohio -- A 76-year-old woman found dead outside the Ohio nursing home where she lived died of hypothermia, authorities say. The Putnam County sheriff is investigating Phyllis Campbell's death at the Hilty Home in Pandora, roughly 50 miles southwest of Toledo.

Campbell was found outside the facility on Sunday morning, when temperatures around much of Ohio were still below freezing.

The sheriff's office said an autopsy showed Campbell died from hypothermia. Authorities haven't released details about what happened. 

The facility is part of Mennonite Home Communities of Ohio, whose CEO said by email Wednesday that it's grieving Campbell's death and extending sympathies to her family. CEO Laura Voth said administrators are working with authorities to conduct a thorough investigation but can't publicly discuss details of the case.
