Nancy Lanza was apparently the only person the gunman was close to in the months before he killed her at home and shot to death 26 people at Sandy Hook Elementary last December.

Lanza collected materials on mass killings and kept a spreadsheet ranking of mass murders. But it’s not clear how much she knew about his obsession.
