BRETTON WOODS - The mother of the Connecticut school gunman was reportedly vacationing in New Hampshire in the days before last week's deadly school rampage, leaving her son at home alone, CNN reported Wednesday night.

Nancy Lanza, a former longtime Kingston resident, was on vacation by herself at the Omni Mount Washington Resort and Hotel in Bretton Woods from Dec. 11 to Dec. 13, according to CNN

Her 20-year-old son, Adam, was reportedly left home alone while she was away, according to the report.

Lanza checked out on Dec. 13 and returned to Connecticut that night, according to the CNN report. She was shot and killed the next morning by Adam before he showed up at Sandy Hook Elementary School in Newtown, Conn., and gunned down 20 children and six adults before killing himself, authorities said.

A representative from the hotel referred all questions to a hotel spokesman who could not be reached for comment Wednesday night.

Nancy Lanza often visited New Hampshire, which is where she was raised and lived until 1998 when she and her family, including Adam, sold their home in Kingston and moved to Newtown.
