NYC shooter obtained weapon from casino supervisor, investigation reveals
Police on Wednesday shared new details about Shane Tamura , the man behind the deadly shooting that claimed four lives at a Manhattan office building housing the NFL's headquarters and other corporate offices.
According to investigators, Tamura purchased both the AR-15-style rifle used in the attack and the car he drove cross-country from his supervisor at a Las Vegas casino. The supervisor, who worked in the surveillance department at the Horseshoe Las Vegas, has not been publicly identified. Authorities say the individual has been cooperative and is not facing any charges at this time.
Tamura paid $1,400 for the rifle, which the supervisor had legally purchased. Police initially believed the weapon had been sold in parts but later clarified that the entire firearm was transferred. It remains unclear whether the private sale itself complied with legal standards.
Detectives have secured a warrant to search Tamura's locker at the casino and are in the process of obtaining additional warrants for his phone and laptop.

The attack began in the building's lobby, where Tamura fatally shot three people. He then rode an elevator to the 33rd floor, where he killed a fourth person before turning the gun on himself.
A note discovered on Tamura's body offered insight into his motive. In it, he expressed anger over the NFL's handling of chronic traumatic encephalopathy (CTE), a brain disease linked to repeated head trauma. Tamura claimed he suffered from CTE himself.
At his studio apartment in Las Vegas, investigators found another note, this one filled with personal anguish. In it, Tamura expressed feelings of failure and disappointment, particularly in relation to his parents, and offered a heartfelt apology to his mother. Police also recovered prescribed medications, including anti-inflammatories and epilepsy treatment.
Authorities confirmed Tamura had a history of mental illness, though specifics have not been released. Detectives plan to speak with his parents as the investigation continues.
