Hartford - The state's Freedom of Information Commission on Wednesday ordered the release of the 911 tapes from last year's shooting at Sandy Hook Elementary School, ruling in favor of an appeal by The Associated Press for access to records withheld by investigators.

The recordings will not be made available immediately. The prosecutor leading the investigation of the Dec. 14 massacre, Danbury State's Attorney Stephen Sedensky III, said the commission's decision will be appealed in Connecticut's courts.

The recordings could shed light on the law enforcement response to one of the worst school shootings in U.S. history. Twenty-six people, including 20 first-graders, were killed inside the school on Dec. 14 by the gunman, Adam Lanza, who committed suicide as police arrived.

Sedensky argued that the calls should be exempt from public information laws because they contain information that could be used in a law enforcement action. But the chairman of the commission, Owen Eagan, said Sedensky did not make clear in his previous testimony how the information might be used or how its release could damage an investigation in which no arrests are anticipated.

"You never even reviewed the tapes," Eagan said, reminding Sedensky of his testimony from June.

Sedensky has raised other arguments against releasing the tapes, saying they could subject witnesses to harassment from conspiracy theorists and violate survivors from the school who deserve special protection as victims of child abuse.

"This is a case about crime victims and witnesses who shouldn't have to worry that their calls for help in their most vulnerable moments will become fodder for the evening news," he said at the start of Wednesday's hearing.

On the day of the shooting, the AP requested documents, including copies of 911 calls, as it does routinely in news gathering, in part to examine the police response to the massacre that sent officers from multiple agencies racing to the school. 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.

The town's police department denied the AP's request, citing legal exemptions that allow the government to withhold documents if they're being used for an ongoing investigation and should remain secret. The AP appealed to the FOI commission.

In testimony before FOI hearing officer Kathleen Ross on June 3, Newtown's police chief said a search for the records was not conducted until three days before his appearance at the FOI commission hearing. Although 911 calls are typically released, Sedensky directed Newtown police not to turn over the recordings while the inquiry was underway.

In a response earlier this month to a hearing officer who recommended the recordings be released, Sedensky said criminals could benefit by the release of material that could later become relevant to the investigation.

"Under the ruling in the proposed decision, the investigators and the state's attorney would be at the mercy of a criminal seeking to find out what law enforcement knows before law enforcement knows the significance of an individual piece of evidence," he wrote.

A Connecticut law passed earlier this year in response to the massacre creates exemptions to the freedom-of-information law for the release of photographs, film, video and other images depicting a homicide victim if those records constitute "an unwarranted invasion" on the privacy of the surviving family members. It also created a one-year moratorium on the release of certain portions of audiotape and other recordings - with the exception of 911 tapes - in which the condition of a homicide victim is described.
