SHEFFIELD — Vermont State Police investigating the abduction and killing of a Sheffield grandmother more than two years ago have returned to her home to search the property.

Mary “Pat” O’Hagan, 78, disappeared from her home in September 2010. Her body was found nearly a month later by hunters in a remote area 10 miles away.

No arrests have been made in her killing.

WCAX-TV reported that detectives searched her property Tuesday to see if anything may have been overlooked.

In November a Vermont state police detective testified that Michael Norrie, a Sheffield man held on other charges, “was confessing to part of the murder” when he stopped cooperating with authorities.
