Another Vermont law enforcement officer has testified in court about claims that a Sheffield man told investigators he was involved in the killing of a 79-year-old grandmother killed two years ago.

The testimony from federal agent James Mostyn was part of a federal court hearing into whether 22-year-old Michael Norrie is able to understand his rights in a case unrelated to the 2010 death of Mary "Pat" O'Hagan.

The elderly woman was abducted from her Sheffield home in September 2010. Her body was found a month later. No one has been charged with her killing

The Burlington Free Press reported that Mostyn testified Wednesday that when Norrie was being interviewed in January 2011 he gave "his essential confession to the murder."

A state police detective has given similar testimony.
