CONCORD, N.H. (AP) — A New Hampshire judge has ruled that several documents can remain sealed in a lawsuit that aims to prevent a Vermont man from inheriting money from the millionaire grandfather the family says he killed. The order was issued Friday in connection with a July lawsuit accusing Nathan Carman of being responsible for the 2013 death of John Chakalos. The family argued unsealing certain documents would impede the investigation into Nathan Carmen.
