The tragic Manhattan shooting at a corporate office building has taken a shocking turn, as authorities reveal the gunman acquired his rifle and vehicle from his supervisor at a Las Vegas casino. This startling connection adds a new layer to the unfolding crime investigation, raising profound questions about the circumstances surrounding the fatal incident and the pathways to such acts of gun violence.
On a somber Monday, Shane Tamura, 27, unleashed chaos in the Manhattan building, fatally wounding three individuals in the lobby before ascending to the 33rd floor where he killed a fourth person and subsequently took his own life. The building, notably housing the National Football League’s headquarters among other corporate entities, became the scene of an unimaginable tragedy that reverberated through the city.
Investigators delving into Tamura’s background discovered a troubling note in his Las Vegas studio apartment, expressing a deep sense of parental disappointment and an apology to his mother. Further searches uncovered psychiatric medication, an epilepsy drug, and an anti-inflammatory, all prescribed to Tamura, providing initial insights into his possible state of mental health.
A pivotal breakthrough in the crime investigation came when detectives learned Tamura purchased the AR-15-style rifle and the car from his direct supervisor within the surveillance department at the Horseshoe Las Vegas. The supervisor reportedly acquired the rifle legally before selling it to Tamura for $1,400, adding a complex dimension to the rifle sale inquiry.
While the supervisor has been cooperative with authorities and currently faces no charges, the legality of the rifle sale remains a central point of the ongoing inquiry. Police had previously misstated that only parts of the rifle were supplied, correcting their information to confirm a full weapon transaction, further intensifying scrutiny on private firearm transactions.
Amidst the relentless crime investigation in both New York and Las Vegas, the victims of the Manhattan shooting are being mourned. Julia Hyman, a real estate firm worker and a 2020 Cornell University graduate, was laid to rest after an emotional service. Security guard Aland Etienne, an unarmed professional, was remembered by his union, having been shot while at his lobby security post.
The New York City Police Department is also preparing for the funeral of officer Didarul Islam, who was tragically killed while working a department-approved second job providing security for the building. Meanwhile, teams of detectives continue their work in Las Vegas, executing search warrants for Tamura’s casino locker and awaiting warrants for his phone and laptop, as they seek to speak with his parents to piece together the full narrative.
Police have indicated Tamura had a history of mental illness, though specific details remain undisclosed. A prior misdemeanor trespassing arrest in September 2023 at a Las Vegas suburban casino, where he became agitated when asked for ID, highlights a pattern of concerning behavior, even though those charges were later dismissed.
This incident starkly underscores the complexities of gun violence and the challenges in preventing such tragedies. Nevada’s red-flag law, which allows for temporary firearm removal from individuals deemed a risk, serves as a crucial tool, yet experts emphasize its efficacy hinges entirely on its proactive utilization by family members or law enforcement when concerns about mental health or dangerous behavior arise.
