Career and Financial Life
Professional Background
Paddock worked as an internal auditor and later as a budget analyst for the government of Los Angeles, according to personnel records. He left that position in the 1970s and transitioned into self-employment, primarily through real estate investing and purchasing retirement homes. Over time, he built a substantial retirement portfolio, which included real estate holdings in Nevada and California.
Gambling and Lifestyle
He was an avid gambler, regularly traveling to casinos in Las Vegas and nearby regions. Investigators noted that he was a high-stakes gambler who routinely won and lost significant sums, often exchanging large sums of cash and using casino markers. His lifestyle was funded by real estate profits and savings rather than employment income.
Personal Relationships and Behavior
Marriage and Social Life
Paddock married a Filipina woman in 1979, and the couple had a daughter. The marriage ended in divorce in the 1990s. Following the divorce, he lived alone in Las Vegas and maintained limited contact with family members. Neighbors and acquaintances described him as private, financially comfortable, and socially isolated.
Behavioral Observations
Multiple associates noted that Paddock exhibited marked behavioral changes in the years before 2017, including increased alcohol consumption, irritability, and periods of withdrawal. He purchased multiple properties in Nevada and the Philippines in the decade preceding the attack. Law enforcement and investigators found no clear political or ideological motive, concluding that mental health, financial independence, and access to weapons were central factors.
The 2017 Las Vegas Shooting
On the evening of October 1, 2017, Paddock opened fire on a country music festival on the Las Vegas Strip from his 32nd-floor hotel suite at the Mandalay Bay Resort. He used a cache of modified firearms and ammunition stored in his room. The attack killed 61 people and injured hundreds before he took his own life as police breached the door. Investigators concluded he acted alone and planned the attack over an extended period.
Post-Incident Findings and Investigations
Following the shooting, the Las Vegas Metropolitan Police Department, the FBI, and other agencies conducted extensive reviews of his financial records, communications, and property transactions. No manifesto or clear ideological statement was found. Reports emphasized his isolation, accumulation of weapons, and deliberate planning, highlighting gaps in identifying and intervening with individuals exhibiting dangerous intentions.
