NYC shooter Shane Tamura's brain will be tested for CTE, medical examiner's office says
A spokesperson for New York City's Office of Chief Medical Examiner told USA TODAY Sports it would be testing for the disease as part of a full neurological work-up of the deceased.
"Our office has neuropathology expertise in house and will be examining the brain as part of the additional testing for the complete autopsy," a spokesperson wrote in an email.
The story was first reported by The Washington Post.
The medical examiner's tests come after Tamura asked in a three-page note, found in his wallet after the shooting, to be tested for CTE, which is a brain condition experienced by people who have repeated blows to the head, often through contact sports such as football.
Tamura claimed his time playing high school football in California caused him to develop CTE. He also wrote in his note the NFL "knowingly concealed the dangers to our brains to maximize profits. They failed us."
CTE can result in a variety of symptoms, including increased aggression, emotional instability and suicidal thoughts and behavior, according to the Mayo Clinic. It can only be diagnosed posthumously.
As of 2023, the Boston University CTE Center had tested 376 former NFL players for the disease. It found 345 of them (91.7%) suffered from CTE. However, an article revealing that data noted the prevalence among all NFL athletes is unknown because it can only be diagnosed after death and "brain bank samples are subject to selection biases."
"While the most tragic outcomes in individuals with CTE grab headlines, we want to remind people at risk for CTE that those experiences are in the minority,' said Dr. Ann McKee, then the director of the BU CTE Center and chief of neuropathology at VA Boston Healthcare System. "Your symptoms, whether or not they are related to CTE, likely can be treated, and you should seek medical care. Our clinical team has had success treating former football players with mid-life mental health and other symptoms."
Chris Nowinski – the CEO of the Concussion Legacy Foundation, which works closely with the Boston University CTE center – cautioned The Washington Post that even if Tamura is diagnosed with CTE, it wouldn't rule out other factors from having contributed to his actions. Those potential factors include mental illness, genetic disorders and drug use.

New 911 calls reveal mother's concerns about NYC shooter Shane Tamura
A trove of new documents and 911 calls give insight into Shane Tamura's mental health before he shot and killed four people in a Manhattan skyscraper. In the years before 27-year-old Shane Tamura walked into a New York City skyscraper and fatally shot four people, he had several run-ins with police and his mother had twice called authorities to report he threatened to kill himself, newly released records show. In 2024 and 2022, Tamura's mother called 911 in Las Vegas telling dispatchers she was worried her son would take his own life. She said he had a firearm and had been diagnosed with bipolar disorder and suffered from insomnia, depression and sports-related concussions. Authorities have said Tamura, a former high school football player, had a history of mental health issues, but the 911 recordings and police reports made public by the Las Vegas Metropolitan Police Department give new insight into Tamura's life in the years before the shooting. On July 28, police say Tamura carried out a mass shooting in New York City, which they believe targeted the National Football League's headquarters. Officials say he drove across the country, walked into a Manhattan skyscraper and opened fire with a rifle, killing four people, including an off-duty police officer and several building workers. He died of an apparent self-inflicted gunshot wound. After the rampage, investigators discovered that he left behind more ammunition, firearms and a three-page note in which he said he suffered from CTE, a brain condition experienced by people who have repeated blows to the head, often through contact sports such as football. The note criticized the NFL, saying it "knowingly concealed the dangers to our brains to maximize profits" and he asked his brain to be studied – a request that is being fulfilled by New York City's Office of Chief Medical Examiner as part of a full autopsy and neurological analysis. The new 911 calls and police reports released by the Las Vegas Metropolitan Police Department include another mental health intervention in 2024, an arrest a year earlier for trespassing at a casino and a traffic violation. The shooting remains under investigation and a full autopsy could take several weeks. Tamura threatened to take his own life in motel room, mother told police In September 2022, his mother called 911 in Las Vegas and told a dispatcher that Tamura started slamming things and threatened suicide while at a motel. She said she was calling from her car but still had a key to the hotel room. Tamura's mother told the dispatcher he had sleeping pills and kept a gun in his backpack. "He didn't say he made a plan, he said that he just can't take it anymore," she told the dispatcher. "I'm afraid to leave." His mother said Tamura was under a doctor's care for depression, sport-related concussions, chronic migraines and insomnia. After officers and a paramedic arrived on the scene an officer filed an emergency request for the former high school football player to be admitted to a mental health facility. A year before shooting, Tamura hospitalized for mental health crisis In August 2024, police and local paramedics went to Tamura's apartment after his mother reported he had threatened suicide. The Las Vegas Metropolitan Police Department released body camera footage showing the responding officer's interaction with emergency medical responders and Tamura. When the officer walked into the apartment, Tamura was sat shirtless while paramedics checked his vital signs. A paramedic at the scene spoke to the officer, telling him that Tamura "called his mom, made some statements about not wanting to be here anymore." The paramedic said Tamura told them he had a gun in his backpack but has been cooperative. The encounter was calm with the officer and paramedics following him as he put on a shirt and grabbed a few items to take with him to a hospital. They walked downstairs and Tamura was put on a stretcher and wheeled into an ambulance. An officer filed an application to admit him into a mental health facility or hospital for treatment related to a mental health crisis, records show. Tamura's police encounters: Traffic violations, trespassing arrest In the two years before Tamura carried out the deadly mass shooting, he was arrested for trespassing at a casino and was issued a citation for driving without a valid license. In May 2024, he was pulled over by a Las Vegas Metropolitan police officer because he did not have a license plate on the back of his car. "I know," he told officers, body camera footage shows. "I'm sorry guys. I know I shouldn't be driving." After checking his license and registration information, an officer approached Tamura and told him he would receive a citation and his car would be towed because his license had been suspended. The officer and Tamura spoke calmly as the officer told him to park his car and get a ride home. About seven months earlier, in September 2023, Tamura had a more aggressive interaction with police and was arrested on a charge of trespassing after he refused to leave a casino, a police report related to the incident said. Police wrote that Tamura had been gambling at a table when an employee asked for his identification. Tamura refused to show it and he was asked to leave the property, according to police. He walked to the cashier clerk and asked to collect $5,000 in winnings. She asked for his ID, as is common practice with such amounts, and he refused again. Police say he got into a heated conversation with security at the casino and at one point attempted to grab one of the security officials He was put on a wall and brought to a holding cell before police brought him outside and said he was free to go as long as he left the property. He refused to leave and was arrested on a trespassing charge, records show.

What an oncologist wants us to know about everyday chemicals
Endocrine disruptors are chemicals that can interfere with the complex system that produces and interacts with our hormones. Research suggests they can affect the reproductive system, our kidneys, and even increase our risk of cancer. There are over 1,000 types of endocrine-disrupting chemicals, according to some estimates, and we are exposed to them daily through things like kitchen utensils and makeup. So how worried should we be about inevitable exposure? Host Elahe Izadi speaks with oncologist Dr. Mikkael Sekeres about the connection between endocrine disruptors and cancer. Dr. Sekeres also shares his advice on steps he takes to avoid these chemicals–and how he puts the risks into perspective. Today's show was produced by Thomas Lu, with help from Rennie Svirnovskiy, who also mixed the episode. It was edited by Ariel Plotnick. Subscribe to The Washington Post here.

NFL bans smelling salts: What are they, and why were they banned now?
The NFL's decision to ban the use of smelling salts and ammonia packets hit George Kittle of the San Francisco 49ers hard. The tight end broke the news on NFL Network on Tuesday saying that he was "distraught" he would be no longer allowed to use them on "every drive" during the season. [Join or create a Yahoo Fantasy Football league for the 2025 NFL season] Why the league is banning smelling salts comes down to player safety, as the NFL says the products are not safe and are used to mask concussions. What are smelling salts and what are they used for? Smelling salts can come in the form of bottled powders or packets that feature ammonia and other chemicals. It is a very strong smell and they are mostly used to treat fainting victims. But athletes have used them for years as a way to become more alert before or during a game in order to boost performance. Once the ammonia fumes are breathed in, it triggers a reaction that sends a jolt of adrenaline throughout the body, while also clearing out nasal passages. 'Ammonia is an irritant,' family medicine physician Elizabeth Rainbolt, MD, told the Cleveland Clinic website. 'It irritates your airways and your lungs. When you breathe it in, you reflexively take a really big breath. It doesn't cause a 'high' per se, but the rush of oxygen triggers your sympathetic nervous system to take over and can make you feel amped up in a way.' Why is the NFL banning smelling salts? NFL Network's Mike Garafolo shared the memo that got Kittle so worked up. Citing a 2024 memo from the U.S. Food and Drug Administration, the NFL explained its reasoning for banning ammonia inhalants (AIs), an umbrella term that includes smelling salts. 'In 2024, the FDA issued a warning to companies that produce commercially available ammonia inhalants (AIs), as well as to consumers about the purchase and use of AIs, regarding the lack of evidence supporting the safety or efficacy of AIs marketed for improving mental alertness or boosting energy. "The FDA noted potential negative effects from AI use. AIs also have the potential to mask certain neurologic signs and symptoms, including some potential signs of concussion. As a result, the NFL Head, Neck, and Spine Committee recommended prohibiting the use of AIs for any purpose during play in the NFL.' The memo clarified that the AI category encompasses 'any form of 'smelling salts'' and prohibits any member of a team from administering or providing AIs to players at any point during a game. The FDA memo referenced by the NFL detailed reported adverse effects of using unapproved AIs that include "shortness of breath, seizures, migraines, vomiting, diarrhea, and fainting from consumers after using these types of products, possibly purchased through various websites." Are they used in other sports? Yes, many athletes across the sports world use them before and during games. Sometimes coaches get involved, too. Have any other sports organizations banned smelling salts? Yes. Hockey Quebec, a branch of Hockey Canada that oversees amateur hockey in the province, banned smelling salts in February, citing concern about their use by youth players.
