HARTFORD, Conn. (AP) — Connecticut's state attorney is planning today to release a report on the investigation into last December's massacre at Sandy Hook Elementary School in Newtown.

But the bulk of evidence is still being withheld. Lead investigator Stephen Sedensky III has gone to court to fight the release of 911 tapes, has consulted with victims' families on what might be included in the report and has resisted calls from Connecticut's governor to divulge more information sooner.
