Investigators planned to release a long-awaited report [on] the Newtown school shooting that could provide some of the first official answers to questions about the history of the gunman and the police response to one of the worst school shootings in history. The summary report by the lead investigator, State's Attorney Stephen Sedensky III, comes nearly a year after the massacre of 20 children and six women inside Sandy Hook Elementary School. The report ... will not include the full evidence file of Connecticut State Police, which is believed to total thousands of pages. The decision to continue withholding the bulk of the evidence is stirring new criticism of the secrecy surrounding the investigation. Dan Klau, a Hartford attorney who specializes in First Amendment law, said the decision to release a summary report before the full evidence file is a reversal of standard practice and one of the most unusual elements of the investigation. Sedensky has gone to court to fight release of the 911 tapes from the school and resisted calls from Connecticut's governor to divulge more information sooner. The withholding of 911 recordings, which are routinely released in other cases, has been the subject of a legal battle between The Associated Press and Sedensky before the state's Freedom of Information Commission, which ruled in favor of the AP, and now Connecticut's court system. If the recordings are released, the AP would review the content and determine what, if any, of it would meet the news cooperative's standards for publication.
