Questions Rise About NYC Shooter's Mental Health and Vegas Job

A Tragic Incident Unfolds

A shocking event occurred in Manhattan when a man, Shane Tamura, 27, entered an office tower with a gun and killed four people before taking his own life. The incident has raised numerous questions about how someone with a documented history of mental health issues could have ended up in such a critical role within the security industry.

Tamura was employed in the surveillance department of a Las Vegas casino, which is known for its rigorous security protocols. However, he did not show up for his usual shift at the Horseshoe Las Vegas on Sunday. Instead, he drove across the country to carry out a mass shooting inside the skyscraper that houses the National Football League’s headquarters. A fifth person, an NFL employee, was injured in the attack.

Investigating the Circumstances

As investigators work to uncover the motive behind the attack, there are growing concerns about how a man with a history of mental health problems managed to work in one of the most security-sensitive jobs in Las Vegas. Caesars Entertainment, the company that owns the Horseshoe, confirmed Tamura's employment but has not disclosed the nature of his role or whether he was authorized to carry a weapon. A spokesperson has not responded to inquiries regarding whether Tamura’s job required him to hold a valid work card from the state Private Investigator’s Licensing Board.

State licensing records indicate that Tamura previously held a license as a private security officer, though it expired in December. While holding that license, he was arrested at a casino in suburban Las Vegas. A report from September 2023 states that he was asked to leave after becoming agitated with casino security and employees who asked for his ID. He was arrested on a misdemeanor trespassing charge, but prosecutors later dismissed the case.

Personal Details and Background

Tamura left a note indicating he had chronic traumatic encephalopathy (CTE), a degenerative brain disease linked to repeated head trauma. Authorities have not provided specific information about his psychiatric history but are investigating claims made in the handwritten note. According to officials, Tamura intended to target the offices of the NFL, accusing them of hiding the dangers of brain injuries linked to contact sports. However, he took the wrong elevator during the attack.

Tamura’s family members have not responded to messages seeking comment. No one answered the door at his family's Las Vegas home on Monday.

High School Years and Community Perception

Tamura did not play professional football but was a standout running back during his high school years in Southern California. Local news accounts described his abilities as “lightning in a bottle.” One of his former coaches, Walter Roby, said he did not remember Tamura sustaining any head injuries during his playing days. He recalled an ankle injury, "but that was the extent of it."

“He was a quiet dude, soft spoken, humble and led by his work ethic more than anything else,” Roby told The Associated Press. “His actions on the field were dynamic.”

Former classmates and neighbors say they didn’t stand out. Some of Tamura's former classmates were stunned by the shooting, and several said they had lost contact with him. Numerous others who attended Golden Valley High School, which has over 2,000 students, weren’t familiar with him. Some of Tamura's neighbors in Las Vegas also said they didn't recognize him after seeing his photo shared in news reports about the shooting.

“They were so unremarkable, or maybe they were never home when I was home,” neighbor Wendy Malnak said about Tamura and his family. Malnak, who has lived in the neighborhood since 2022, noted that many residents on what she described as a quiet street keep in touch regularly and look out for each other, yet none of them seemed to notice Tamura or his family before police officers showed up Monday night and surrounded their house.

Ongoing Investigation

Las Vegas police said Tuesday they were “supporting the NYPD with their investigation” but have not released details about the police activity Monday at Tamura's home. Two groups of New York City detectives were on their way to Las Vegas to conduct interviews and search the home, according to New York City Police Commissioner Jessica Tisch.

Authorities are also questioning an associate of Tamura who bought a component of the AR-15-style assault rifle used in the attack. Tisch said Tamura had “assembled” the weapon and used his concealed carry permit to purchase another firearm, a revolver, last month. “This is part of a larger effort to trace Mr. Tamura’s steps from Las Vegas to New York City,” she said.
