A report on the massacre at Sandy Hook Elementary School is set to be released today (Monday). Connecticut officials say it will detail findings from the nearly year-long investigation. A state's attorney spokesman tells CNN family members of the victims have been informed of the report.
Last December, authorities say 20-year-old Adam Lanza killed his mother at their home in Newtown before opening fire at Sandy Hook. Lanza killed 26 people at the school, 20 of them children, before turning a gun on himself.
