Mass Shooting in Midtown Manhattan: Suspect's Background and Investigation

Shane Tamura, a 27-year-old resident of Las Vegas, has been identified as the gunman responsible for the tragic mass shooting that took place on July 28, 2025, at 345 Park Avenue in Midtown Manhattan, New York City. The building houses the NFL headquarters among other offices, and the shooting resulted in four fatalities and injuries to others before Tamura took his own life[1][2][5].

Tamura drove from Las Vegas to New York City on the day of the shooting. Upon arrival, he double-parked a BMW outside the building and entered around 6:30 p.m. ET, armed with an assault-style rifle and wearing body armor[1][2]. In the lobby of the skyscraper, he first shot an off-duty police officer and multiple others before taking an elevator to the 33rd floor where he shot another victim. He then shot himself with the rifle[1].

The New York Police Commissioner, Jessica Tisch, confirmed that Tamura had a documented mental health history, including reports of suicide attempts[2][3]. His mother made two 911 calls about suicide attempts. One specific call in August 2024 reported a bipolar episode[3][4]. Despite his mental health struggles, he maintained an active concealed carry permit in Nevada[3].

Tamura lived in a gated community in Las Vegas and had a concealed firearms permit issued by the Las Vegas Police Department and a previously expired work card from the Nevada Private Investigators Licensing Board[2]. He completed high school in the Los Angeles area and was a competitive football player, described by a former classmate as a "goofball" with no obvious mental health issues at that time[2].

The investigation has revealed that Tamura had several prior interactions with police and security personnel related to mental health and legal issues. On September 27, 2023, he was involved in an incident at Red Rock Resort casino in Las Vegas where he refused to show ID and was asked to leave. He was arrested for trespassing after refusing to leave and becoming emotional, mentioning financial stress[1][3][4]. In May 2023, he was pulled over for driving without a license[4]. Bodycam footage from 2022 shows a similar casino incident where he won money but refused to identify himself to cash out winnings[4].

Police found additional ammunition, a revolver, a backpack, and medication in Tamura's vehicle after his arrest[2]. The associate and others have been located and will be questioned about the purchase of the lower receiver used to assemble the AR-15 style assault rifle Tamura used in the shooting[1].

NYPD detectives have traveled to Las Vegas to further investigate Tamura's tracks as part of the ongoing probe. A suicide note was found in Tamura's wallet, containing three pieces of paper from different notebooks. One of the pages was marked with "My Daily Affirmations." The identity of the "Rick" mentioned in the suicide note remains unconfirmed by police sources[1].

Craig Clementi, an NFL employee, was injured as a result of the shooting and was treated at a nearby hospital. He is expected to survive[1]. The investigation is ongoing, and the NFL has faced criticism for its handling of players with head injuries over the years, with links to the brain disorder referred to as CTE (chronic traumatic encephalopathy) being a significant concern[1].
