Casino Employee in Las Vegas Sells Assault Rifle Later Used in New York City Shooting Incident
Headline: No Charges Against Horseshoe Supervisor in Manhattan Shooting Incident
The supervisor at the Horseshoe Las Vegas casino resort, who sold the AR-15-style rifle used by Shane Tamura in the tragic shooting incident in Manhattan, has not been reported as charged as of the latest information available.
On July 30, 2025, Tamura, a former employee of the casino's surveillance department, purchased the rifle from his supervisor. It was later used in the shooting incident that claimed the lives of four individuals across two locations in Manhattan.
Tamura, who had a history of mental illness, also bought a BMW from his supervisor and drove it across the country to commit the atrocity. The revolver found in his car was legally purchased in a separate transaction in Nevada on June 12.
Investigations revealed that Tamura had left a note in his wallet, blaming the NFL for hiding the dangers of brain injuries and apologizing to his Horseshoe supervisor. The note read, "I love you Momma, I'm sorry."
A search of Tamura's Las Vegas apartment revealed anti-psychotic, anti-epileptic, and anti-inflammatory medications, 100 rounds for the revolver, a single rifle round, and no ID.
It is unclear if the gun sale was legal or if any charges have been filed against the supervisor. The police initially reported that only parts of the rifle were supplied, but it was later confirmed that the entire rifle was sold.
In September 2023, Tamura was arrested on a misdemeanor trespassing charge at Red Rock Casino Resort in Las Vegas' Summerlin suburb. He refused to leave the property after being detained by police for demanding $5,000 without showing his ID.
As of Wednesday, the New York police contingent was in Las Vegas, where they obtained a warrant to search Tamura's Horseshoe locker. The search did not lead to any immediate charges against the supervisor.
