AUGUSTA — Autopsy results that might indicate the manner and cause of death of 58-year-old Debra Barton were unavailable late Thursday.

“There’s more work to be done on this death investigation,” said Steve McCausland, spokesman for the Maine Department of Public Safety. “Medical examiners need to run additional tests, and we likely will be doing additional interviews.”

Barton was found dead Wednesday by family members in her home, at 789 Main St. in Readfield.

Police questioned family members that day, and Dr. Margaret Greenwald, the state’s chief medical examiner, was called to the home. An autopsy was set for Thursday.

No other information was available, and police have not classified the death as suspicious.
