NYC Shooter’s Former Security Guard Role in Nevada Revealed

Oh, this should be good. I’m Avery Sinclair, your cynic in chief, here to strip away the fluff and show you what actually happened with Shane Tamura.
Shane Tamura, the man responsible for the Monday rampage in Manhattan, used to be an unarmed security guard in Nevada. According to a representative for Securitas USA, Tamura passed all the standard background screenings when he was hired and displayed an unremarkable work history. He resigned in 2021 without any red flags noted, the rep told TMZ.
Fast forward to yesterday’s tragedy and ABC News reports that Tamura had settled in Las Vegas. He landed a surveillance department position at the Horseshoe Hotel & Casino and kept a low profile. Not a single gun was part of his uniform back then, but something clearly changed.
On Monday evening, in broad daylight, Tamura walked into 345 Park Avenue with an assault rifle. He unleashed gunfire in the lobby, killing three people—including an off-duty NYPD officer—and then rode the elevator to the 33rd floor. There, a fourth victim was killed before Tamura turned the weapon on himself, shooting into his chest.
Authorities later found a handwritten note in Tamura’s wallet. It blamed the NFL for his alleged chronic traumatic encephalopathy and demanded accountability from the league’s offices, conveniently located at the same Park Avenue address. It’s unclear when or where he claimed to have suffered the injuries, but the note was confirmed by law enforcement sources cited by TMZ.
This entire scenario feels like a preventable disaster with a tragic veneer of unpredictability. The fact that a major security provider saw no issues in his past only underscores how thin the margin can be between routine background checks and life-or-death outcomes. Even after he left Securitas USA, Tamura remained in surveillance roles, a job anyone might see as harmless. Turns out, appearances can be deceiving.
There’s no evidence his previous colleagues suspected anything more than a quiet, capable guard. Yet here we are, sifting through police reports and casino records to piece together how someone passed muster one minute and became a mass casualty perpetrator the next.
For all the chatter about corporate screening processes, Tamura’s case raises bigger questions about mental health resources, head-injury awareness, and the limits of background investigations. The note about CTE points to deeper issues that no security firm or casino job could reveal or resolve.
So there you have it – another tragedy with all-too-familiar warning signs. Stay tuned for what unfolds next in this ongoing investigation.
