A prosecutor says the husband of a Massachusetts woman who's been missing since New Year's Day went online to look up ways to dismember and dispose of a body, and clothes and other items belonging to the woman were found at a trash processing facility. The details were given Wednesday at his arraignment on murder and other charges. Not guilty pleas were entered on behalf of 47-year-old Brian Walshe. He was held without bail in Quincy District Court at Wednesday's arraignment. He did not speak except to tell the judge he understood the charges. His attorney did not contest bail but in the past has said her client has cooperated with investigators.
