One year after Stephen Paddock killed 58 Las Vegas concertgoers, criminal psychologists and threat-assessment experts are still puzzling over why a wealthy, 64-year-old gambler committed the deadliest mass shooting in modern U.S. history. Experts are used to finding answers as to why mass shooters commit their crimes, be it anger at co-workers or fellow students over perceived slights, terrorism or mental illness. Typically, mass shooters are younger men who nurse real or perceived grievances, according to a recent FBI study of 63 such attackers. Dr. Palarea said that in mass shootings when there is no grievance, the motive is often infamy. When Las Vegas police revealed that Paddock had also scoped out other rooms high above other outdoor concert venues, he said, it confirmed his suspicions that Paddock wanted to kill as many people as possible.
