HARTFORD, Conn. (AP) — The glimpses of Adam Lanza's home life in a report on the Newtown school massacre are renewing the debate over how much responsibility for the tragedy his mother might bear.
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.
Connecticut's governor said Tuesday that it was bewildering why Nancy Lanza fostered her son's interest in guns even though she knew he was troubled.
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.
