Nancy Lanza, 52, gunman's mother

(AP) -- She once was known simply for the game nights she hosted and the holiday decorations she put up at her house. Now Nancy Lanza is known as her son's first victim.

Authorities say her 20-year-old son Adam gunned her down before killing 26 others at Sandy Hook. The two shared a home in a well-to-do Newtown neighborhood, but details were slow to emerge of who she was and what might have led her son to carry out such horror.

Kingston, N.H., Police Chief Donald Briggs Jr. said Nancy Lanza once lived in the community and was a kind, considerate and loving person. The former stockbroker at John Hancock in Boston was well-respected, Briggs said.

Court records show Lanza and her ex-husband, Peter Lanza, filed for divorce in 2008. He lives in Stamford and is a tax director at General Electric. A neighbor, Rhonda Cullens, said she knew Nancy Lanza from get-togethers she had hosted to play Bunco, a dice game. She said her neighbor had enjoyed gardening.

"She was a very nice lady," Cullens said. "She was just like all the rest of us in the neighborhood, just a regular person."
