A man sentenced to eight years of probation after pleading guilty to involuntary manslaughter in the death of another man outside a Northampton bar is being sent to jail for violating the terms of his release. The Daily Hampshire Gazette reported that James Duffy Jr., of Easthampton, was sentenced to 2½ years in jail Thursday after pleading guilty to violating probationary terms by drinking alcohol. Duffy pleaded guilty in 2010 in the January 2009 death of John Connell outside the Silk City Taproom. Prosecutors say Duffy shoved Connell down a set of steps outside the bar after an altercation inside. Connell hit his head on the ground and later died.
