Who was the shooter?
Identity and basic profile
Stephen Craig Paddock (April 9, 1953 – October 1, 2017) was a 64-year-old white male from Mesquite, Nevada. He was a retired accountant and avid gambler with no known history of mental illness or criminal behavior. Paddock checked into the Mandalay Bay on September 25, 2017, and brought multiple firearms into the hotel. His actions and motive remain extensively investigated, with law enforcement concluding he acted alone and had no direct connections to terrorist organizations.
Weapons and preparation
Paddock amassed a significant arsenal, including at least 23 firearms—many equipped with bump stocks that increase firing rate—along with thousands of rounds of ammunition. He installed cameras in his room and completed extensive pre-attack reconnaissance of the venue and escape routes. This level of planning and material preparation is consistent with findings from federal and local investigations, which emphasize the premeditated nature of the attack and the absence of a clearly defined personal grievance or extremist ideology.
