The woman’s body was in an unoccupied house.

NEWRY (AP) – A 59-year-old woman walked barefoot and in her pajamas in bitterly cold temperatures from her bedroom to an unoccupied house where her body was found, state police said Sunday as an investigation continued.

An autopsy Sunday on Brenda Desatnick’s body was completed, but the cause of her death will not be known until further tests are done, a state police spokesman said.

“From our standpoint, there is no indication of foul play,” added spokesman Stephen McCausland of the Maine Public Safety Department.

McCausland said he didn’t know what tests had been ordered.

“Typically, that means a blood alcohol content test,” McCausland said. “I’m not sure if the medical examiner ordered further toxicology tests.”

Desatnick’s body was found at about 5:30 p.m. Saturday on the front porch near the main entrance of a home two-tenths of a mile from a house she and her husband Allen, 63, of Marblehead, Mass., own, McCausland said.

The house stands along an access road to the Sunday River ski area in western Maine near Bethel.

The Desatnicks and another couple who were visiting them stayed up late Friday night, the spokesman said. When they arose Saturday morning, they found Brenda Desatnick gone and the window to the bedroom where she slept open. She was reported missing at 1 p.m.

Maine game wardens and local rescue workers began a search for Desatnick. Footprints outside the window and leading away from the house showed she was barefoot, McCausland said.

Desatnick walked to two other unoccupied houses before stopping at the third home, where her body was found, McCausland said.

The temperature dipped to a low of minus-6 degrees in the Bethel area on Saturday morning, the National Weather Service in Gray said. The high on Friday was 9 degrees.
