(CNN) — A report on the investigation into the Sandy Hook Elementary School shooting will be released Monday, Connecticut state officials announced.
The report will provide a summary of the almost yearlong investigation of the Dec. 14, 2012, shooting that left 26 people dead, including 20 children.
The summary of the second-deadliest shooting in U.S. history is expected to be about 50 pages long, said Mark Dupuis, a spokesman for Danbury State’s Attorney Stephen Sedensky, whose office conducted the investigation.
Victims’ family members have been informed of the report, Dupuis told CNN on Friday.
Dupuis declined to provide details about when, where, and how the families were given the details of the report.
“We are sensitive to the needs of the families, and those needs are being addressed,” Dupuis said.
The family of Virginia Soto, a teacher who shielded her students before being shot to death, said the release of the report is “yet another blow that our family has been dealt.”
A statement from the family said, “While others search for the answer as to why this happened, we search for the how. How can we live without Vicki? How do we celebrate Christmas without Vicki? How do we go on every day missing a piece of our family? Those are the questions we seek the answers for. There is nothing in the report that will answer those for us.”
The report, which will be available on the office’s website Monday afternoon, is separate from a much longer evidence file that Connecticut State Police will release at an unspecified date.
The shooter, identified as 20-year-old Adam Lanza, killed his mother before opening fire at the school. He then killed himself, officials said. His mother’s body was found at the family’s Newtown residence.
