Nancy Jean Champion Lanza, 52, was killed on December 14, 2012, at her home in Newtown, Connecticut. The state’s Chief Medical Examiner determined she died from multiple gunshot wounds to the head inflicted with a .22-caliber rifle. Police say there were no other suspects in her death.

A former Kingston, New Hampshire, resident born in Salem, Massachusetts, Nancy had lived in Newtown since 1998. She worked for John Hancock Mutual Life Insurance until 1992, attended the University of New Hampshire, and graduated from Sanborn Regional High School. Family and neighbors described her as kind and giving; she volunteered at local charities, enjoyed flower gardening, travel, the arts and jazz, and was an avid Red Sox fan.

Investigators later reported the same individual responsible for the killing of Nancy Lanza also carried out a mass shooting at Sandy Hook Elementary School that morning. Official reviews concluded he acted alone and planned his actions, but did not establish a clear motive. Did anyone who knew Nancy notice anything unusual in her life or routine in the months before December 2012?
