Police say the man who shot and killed four people in a New York City skyscraper spent days traveling across the country to reach his target. Murders such as these are increasingly common as the United States becomes desensitized to mass shootings. Investigators say Shane Tamura, who lived in Las Vegas, went through Colorado, Nebraska and Iowa before arriving in New Jersey yesterday afternoon. Just a few hours later, he was in midtown Manhattan with an assault rifle.
Those details evoked memories of Luigi Mangione’s journey from Georgia to New York last December, where he allegedly assassinated the CEO of United Health Care. In both cases, the men had nurtured grievances, Mangione with the health care system, Tamura with the NFL over its past reactions to brain injuries among football players.
“Social media has certainly had an impact,” said Northeastern University criminology Professor James Alan Fox. “If someone has a grudge, a grievance, they can find other people online who will support them, who confirm their ideology.”
