A dispute over the 911 recordings from the shooting at Sandy Hook Elementary School is shaping up as a test of a new Connecticut law — adopted in response to the massacre — that prevents public release of certain records in homicide cases.

The Associated Press is challenging the refusal by investigators to release the tapes from the Dec. 14 shooting. A hearing officer for Connecticut’s Freedom of Information Commission has recommended the tapes be released, and the full commission is meeting Wednesday to consider the case.
