(CNN) — A report on the investigation into the Sandy Hook Elementary School shooting was released Monday, Connecticut state officials announced.
The report, released at 3 p.m. ET, said that police arrived on the scene fewer than 4 minutes after the first 911 call and that the shooter, identified as 20-year-old Adam Lanza, killed himself one minute later.
“In fewer than 11 minutes twenty first-grade pupils and six adults had lost their lives,” it said.
The report was further expected to provide a summary of the almost yearlong investigation of the December 14, 2012, shooting that left 26 people dead, including 20 children.
The summary of the second-deadliest shooting in U.S. history is 44 pages long.
Victims’ family members were informed of the report, said Mark Dupuis, a spokesman for Danbury State’s Attorney Stephen Sedensky, whose office conducted the investigation.
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 Victoria 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 is available on the Connecticut Division of Criminal Justice website, is separate from a much longer evidence file that Connecticut State Police will release at an unspecified date.
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.
