Identification of the Suspect

The shooter was soon identified as 27‑year‑old Shane Devon Tamura, a Las Vegas resident, found dead from an apparent self-inflicted gunshot wound on the 33rd floor stairwell or office area of the building. A concealed carry permit issued in July 2022 by Las Vegas bearing his name and photo was recovered at the scene, confirming his identity. A vehicle registered to him in Nevada, with a rifle case inside, was found on site.

Weapon Involved

Tamura was armed with a Palmetto State Armory AR‑15‑style rifle, .223 calibre, equipped with a black scope, green handguard, and a 30‑round magazine. The rifle was found blood‑stained on the 33rd floor after the shooting ended; witnesses described the sound as a “barrage” echoing in the lobby and hallways.
