Las Vegas Casino Supervisor Sold Gunman Rifle Used In Deadly NYC Attack

2 days ago Authorities say the 27-year-old man who killed four people at a Manhattan office building bought the rifle he used in the attack and the car he drove across country from his supervisor at a Las Vegas casino. Police say Shane Tamura fatally shot four people in the building that houses the National Football League’s headquarters on Monday before killing himself. New York police said Wednesday that Tamura’s supervisor at the Horseshoe Las Vegas legally bought the AR-15-style rifle he sold to Tamura for $1,400. It isn't clear yet if the gun sale was legal. Police say Tamura believed he had a brain disease linked to contact sports and accused the NFL of hiding the dangers of playing.
