What Happened: Timeline and Immediate Response

Investigation Findings and Evidence
Shooter Profile and Motives
Stephen Craig Paddock, a 64-year-old retired accountant from Mesquite, Nevada, was identified as the sole shooter. Investigators found no clear, definitive motive; reports noted longstanding planning, access to numerous firearms, and possible health or personal factors under review, but a conclusive motive was never publicly established. Authorities emphasized the unprecedented scale of the premeditation and weaponry involved.
Weapons and Equipment
Paddock legally acquired the firearms involved, modifying some with bump stocks to simulate automatic fire. He used multiple handguns and rifles, firing from the hotel suite through broken windows toward the crowd. Ballistic analysis and crime scene reconstruction confirmed the volume and pattern of fire, contributing to the high casualty count.
