Documents filed by the U.S. Attorney's office allege three men had a role in the 2010 abduction and killing of a Sheffield grandmother.
The three, who are related, are in federal or state custody on charges unrelated to the killing of 78-year-old Mary "Pat" O'Hagan. No one has been charged in her death.
Hagan disappeared from her home in September 2010. Her body was found nearly a month later by hunters in a remote area 10 miles away.
The Burlington Free Press reports the court paperwork provides different reasons for the killing, such as robbery and O'Hagan learning about meth being cooked at an abandoned home.
Lawyers for the men have either declined to comment, could not be reached for comment, or did not respond to messages seeking comment.
