2017 Las Vegas Shooting: Preliminary Investigative Report

The Las Vegas Metropolitan Police Department (LVMPD) released an overview report on January 18, 2018 covering the investigation on the October 1, 2017 Las Vegas shooting. The shooting, carried out by 64-year-old suspect Stephen Paddock, was the deadliest mass shooting in modern history, and left 58 deceased and over 700 injured.

The 81-page report, titled “LVMPD Preliminary Investigative Report: 1 October/Mass Casualty Shooting,” is an investigative overview of the shooting, which is still an open case. It addresses the number and identities of known victims to date, surviving victims, and known facts regarding the events that occurred in the days leading up to the shooting. It provides details on the hotel selected by Paddock from which he targeted concertgoers, maps of the hotel and crime scenes, and the specifics of the sequence of events that unfolded during and after the shooting.

By outlining the details of Paddock’s actions in the two weeks prior to the shooting, the LVMPD shows how Paddock was methodically preparing for the attack, and had some recent stressors that may have had influence. Further, the report discusses the personality of Paddock through the eyes of those who knew him, particularly his tendency to show little emotion and recent change in behavior.

Another notable point raised in the report (pages 46-48 of the document) is the evolution of his online searches, which began with outdoor summer 2017 convert venues and eventually led to searches about military and law enforcement-grade weapons. These elements point to an escalation of already concerning behavioral tendencies, as described by family members and his physician.

LVMPD will release a final comprehensive report upon completion of the investigation.
