Newtown, Connecticut (CNN) -- The mother of the man identified by authorities as the gunman behind an elementary school massacre liked to play parlor games in a ladylike setting with neighbors, discussing their landscaping and backyard gardens in this charming exurb some 60 miles from New York City. Nancy Lanza was a personable neighbor who lived on a block of spacious houses on a crest overlooking gentle hills, acquaintances said. She and her family moved to the Sandy Hook neighborhood about 1998, raising two sons with husband Peter until the couple separated a few years ago. "It was just a nice, normal family," neighbor Rhonda Cullen said Saturday, recalling a recurring neighborhood ladies night over the Bunco dice game.
