FILE - In this Thursday, Dec. 20, 2012, file photo, a photograph of Nancy Lanza, bottom left, one of the 27 people killed by Adam Lanza in the Sandy Hook village of Newtown, Conn., appears on a board at a makeshift memorial in Newtown, Conn. Thousands of pages of documents from the Newtown shooting investigation help fill out the picture of Nancy Lanza as a dedicated and loving, if bewildered, parent who acknowledged her son Adam appeared to be spiraling downward but was not aware to what extent. On Dec. 14, 2012, Adam fatally shot her in her bed, gunned down 20 first-graders and six educators at Sandy Hook Elementary School in one of the worst mass shootings in the nation’s history, and killed himself with a handgun as police closed in.
