"Danbury State's Attorney Stephen J. Sedensky, III, said this week that five search warrants which were issued to police investigators in probing the mass murder remain under court seal.
Mr Sedensky sought and received a judge's approval to keep those five warrants sealed from public review for 90 days to protect the ongoing crime investigation. He declined to describe the specifics of the warrants.
Those warrants would now be unsealed with their contents disclosed by late March, unless the state seeks and receives from a judge another time extension to keep them sealed.
In a statement on the investigation, the Chief State's Attorney's Office said that the Danbury State's Attorney's Office will continue to work with the state police, Newtown police, Office of the Chief Medical Examiner, and other local, state, and federal agencies on the crime probe.
"It cannot be stated too often how invaluable and necessary the work of the United States Attorney's Office, the Federal Bureau of Investigation, the United States Marshals Service, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and other federal agencies was and is to this investigation," it added.
Once the investigation has been completed and all documents and evidence are reviewed, Mr Sedensky "will make any appropriate decisions regarding prosecutions pursuant to state law and will issue a report of the incident with input from all agencies involved," according to the statement."
