After an 11-month investigation, the Connecticut State Police could not determine a motive behind last year's shootings at Sandy Hook Elementary School in Newtown that left 20 first-grade students and six adults dead. The New York Times says that a 48-page report issued Monday afternoon by Stephen J. Sedensky III, the state’s attorney in Danbury, provided some new details, but much of the information has been heavily redacted.
From the report: "The obvious question that remains is: “Why did the shooter murder twenty-seven people, including twenty children?” Unfortunately, that question may never be answered conclusively, despite the collection of extensive background information on the shooter through a multitude of interviews and other sources. The evidence clearly shows that the shooter planned his actions, including the taking of his own life, but there is no clear indication why he did so, or why he targeted Sandy Hook Elementary School."
