In Today's Sandy Hook Report: 'Disturbing' Details

After repeated delays and criticism of excessive secrecy, Connecticut prosecutors plan to release a report at 3pm today on the probe of last year's Newtown school massacre. The report, which comes almost a year after gunman Adam Lanza killed 20 children and six adults inside Sandy Hook Elementary School before taking his own life, will summarize the police investigation and is not expected to recommend any criminal charges, reports the Hartford Courant; the Boston Herald adds that officials are warning that it contains disturbing details. The full state police report is thousands of pages long and no date has been set for its release.

Authorities have yet to reveal information including Lanza's mental health records, clues to a motive, or emergency dispatcher recordings, reports the AP, which has been fighting in court to have 911 calls and other evidence released. Investigators have defended the secrecy surrounding the report, saying victims' families have voiced concerns about what can be released publicly—and some have been harassed by conspiracy theorists. Some evidence will never be made public: A state law introduced after the massacre exempts homicide crime scene photos from freedom-of-information laws if they can be considered an invasion of the privacy of surviving family members.
