Uvalde investigation: A fact-focused report on the school massacre is expected to be released to the public Sunday

The report is expected to focus on the facts of the attack, include a chronological sequence of events, a timeline, a law enforcement manifest, and details on the shooter, a source previously told CNN. It is expected to clarify conflicting accounts of what happened, include verbatim quotes from sworn testimony, and show that the law enforcement failure that day was much greater than one person or one agency, one source has said.

Republican state Rep. Dustin Burrows, the committee chairman, said last month the group would do “everything in its power” to provide facts and answers about what happened “leading up to, during, and in the aftermath of this tragedy.”

Families of the victims are expected to receive the report and hallway surveillance video, with no audio, of the law enforcement response on Sunday morning to provide them with an opportunity to review it before meeting with members of the investigative committee. The surveillance footage was leaked and published by the Austin American-Statesman newspaper on Tuesday, sparking outrage from both local officials and families who said they were blindsided and disrespected by the unexpected release.

The investigative committee’s report and the video are expected to be released to the public concurrent with Sunday’s meeting with family members. A news conference is scheduled for Sunday afternoon for members of the press to ask the committee questions. CNN will read the report once it is made public and will update this developing story.

“The only thing stopping a hallway of dedicated officers from entering rooms 111 and 112 was the on-scene commander, who decided to place the lives of officers before the lives of children,” McCraw said at the time.
