Route 142 between Northfield and the Vermont border was closed for a good part of Monday as Massachusetts and Vermont State Troopers dealt with a reportedly suicidal man.  Residents of West Northfield received a reverse 911 call, telling them to stay inside.  Both lanes of 142 were closed for much of the day, and reopened short before 6:00 Monday night.  Police have not released any details about the man in question.
