LIVE – Updated at 18:35

New York Mayor Eric Adams says the city is sending two teams to Las Vegas as part of the investigation into the mass shooting at a Manhattan skyscraper on Monday evening.

They will be executing a search warrant and tracing two firearms recovered at the scene after Vegas resident and casino employee Shane Tamura, 27, stormed the office building at 345 Park Avenue shortly before 6:30 p.m. Monday, “spraying” the lobby with bullets from an AR-15-style rifle.

Tamura took an elevator up to Rudin Management’s 33rd-floor office, where he continued firing rounds, before turning the gun on himself, according to Police Commissioner Jessica Tisch. Other tenants barricaded themselves in their offices before being led to safety by police.

An NYPS officer, a security guard, a Blackstone executive, and an associate at Rudin have been named as the victims. The NFL said one of its employees was seriously injured.

Mayor Adams said Tuesday that Tamura “appeared to have gone to the wrong floor” and had intended to reach the NFL offices located on the lower levels. A note left by Tamura blamed playing football for his alleged chronic traumatic encephalopathy (CTE).

Shooting was New York's deadliest in 25 years

18:31 , Oliver O'Connell

Monday’s shooting that left four people dead, in addition to the gunman, in a Midtown Manhattan skyscraper was New York City’s deadliest single shooting in 25 years.

The New York Times reports that the last time a shooting in the five boroughs recorded a higher toll was in 2000.

In that incident, five people were fatally shot and two were injured at a branch of the fast food chain Wendy’s in Flushing, Queens, during a robbery, according to former police officials and published reports.

Tight security and strict gun laws make incidents such as that on Monday evening rare in the city. Mass shootings, particularly those involving a rifle, and not connected to another crime, such as a robbery or drug deal, do not tend to happen.

“I don’t recall a time in the last two decades that we’ve had a stranger mass shooting like this,” James Essig, the former chief of detectives at the New York Police Department, told the Times. “Just doesn’t happen here.”

NFL community begins reacting to shooting at the league’s office

18:30 , AP

A couple of NFL coaches opened their news conferences Tuesday by talking about the shooting at the league’s New York City office.

Brian Daboll of the New York Giants and Raheem Morris of the Atlanta Falcons offered their thoughts and prayers to the victims of the shooting. When asked if he had talked to players or staff about the shooting or if they feared for their safety, Daboll said he had not yet had any conversations in that regard.

In a memo to staff, NFL Commissioner Roger Goodell praised the swift law enforcement response and honored the off-duty police officer who was killed in the attack.

What weapon did the shooter use?

18:19 , Oliver O'Connell

The outlet identifies it as a .223-caliber Palmetto State Armory M4 assault rifle, equipped with a black scope, a handguard, and a shoulder sling.

The AR-15 style gun retails for approximately $500 and was equipped with a high-capacity magazine.

Security guard 'assassinated' before he could disable elevators

18:12 , Oliver O'Connell

New York Mayor Eric Adams told CBS Mornings that the security station in the lobby of 345 Park Avenue includes an alarm button that disables the elevators in an emergency.

A security guard was attempting to activate the alarm, “but he was assassinated behind the counter as he attempted to hide himself behind the counter,” Adams said.

The security guard has since been named as Aland Etienne by the 32BJ union, which represents security and janitorial staff in the city.

Manhattan DA pays tribute to slain officer

In a statement, Manhattan District Attorney Alvin Bragg called the shooting “horrific and senseless.”

He said Didarul Islam, the off-duty police officer who was killed, was a “beloved family man and brave public servant.”

Trump cuts more than half of all federal funding for gun violence prevention

17:52 , Oliver O'Connell

President Donald Trump’s administration has cut more than half of all federal funding for gun violence prevention programs, according to a new report.

The Justice Department slashed 69 community violence intervention grants in April, ending more than $158 million in funding, Reuters reports. These grants were directed to several cities throughout the U.S., including Baltimore, Chicago, Los Angeles, New York, and Washington, D.C.

The grants helped fund several programs that work to prevent gun violence. These included training outreach teams to de-escalate conflict, social workers to connect people with key services, and programs for hospitalized gun violence victims, Reuters reports.

Katie Hawkinson has the details.

Gunman worked at Las Vegas casino

17:33 , Oliver O'Connell

The gunman, Shane Tamura, was employed by the Horseshoe Las Vegas hotel and casino, a spokesperson confirmed in a statement to CNN.

“We can confirm that Shane Devon Tamura was a surveillance department employee at Horseshoe Las Vegas. Our thoughts are with the victims, their families, and all those affected by this tragic event. We are cooperating with law enforcement and will not be commenting further,” the statement read.

In remarks on shooting, Schumer reveals he once worked in building where it occurred

Senate Minority Leader Chuck Schumer opened his remarks in Congress this morning on yesterday's midtown Manhattan mass shooting: “I come to the floor this morning not as Democratic leader, not even as the senior Senator from New York, but simply as a New Yorker. As a kid from Brooklyn, as someone who's walked that stretch of Park Avenue a thousand times. Yesterday, my city, the greatest city on Earth, was shattered when a gunman took the lives of four innocent New Yorkers in cold blood, just four blocks from my office in midtown Manhattan. I actually worked in the building where the shooting took place for one summer as a summer associate at a law firm.”

New York sending two teams to Las Vegas as part of investigation

17:22 , Oliver O'Connell

New York Mayor Eric Adams told CNN that the city was sending two teams to Las Vegas as part of the investigation.

They will execute a search warrant and trace the two firearms that were recovered.

He told Wolf Blitzer the city’s medical examiner would decide whether to test the gunman for chronic traumatic encephalopathy (CTE), the degenerative disease that can definitively be diagnosed only after an autopsy.

“The motive appeared to be connected to the shooter’s belief that he was suffering from CTE and [the claim that] he was an ex-NFL player,” Adams said. “Those items just don’t pan out. He never played for the NFL.”

Asked if the gunman had been on the radar of law enforcement, Adams said: “He was not on our radar at all.”

NYPD’s Didarul Islam lauded as hero who tried to stop NFL shooter Shane Tamura. Here’s what we know

17:10 , Oliver O'Connell

The “hero” New York Police Department officer killed by a lone gunman in the lobby of a Midtown Manhattan office tower was a married father of two whose wife is reportedly pregnant with their third child.

Didarul Islam, 36, died making “the ultimate sacrifice” after gunman Shane Tamura stormed into 345 Park Avenue shortly before 6:30 p.m. Monday with an M4 rifle, police said.

Rhian Lubin reports.

Fourth victim named

17:02 , Oliver O'Connell

Security Guard Aland Etienne was also killed in the lobby of the building. His identity was confirmed by Manny Pastreich, the president of the union 32BJ that represents security and janitorial personnel in the city, The New York Times reports.

Police said he was shot while staffing the security desk.

Pastreich said Etienne “took his job duties extremely seriously,” and called him “a New York hero,” adding, “We will remember him as such.”

“We are very saddened about the tragic loss of life … thankfully, everyone at (our) firm is safe," said Mitchell S. Nussbaum, co-chair of law firm Loeb & Loeb, which has offices on the 18th to 22nd floors of the building.

Nussbaum, who was not present during the incident, stated that staff are working from home and will continue to do so for the rest of the week.

He said employees sheltered in place until police escorted them out last night. The final group of staff was escorted from the building sometime after 10 p.m. ET.

Report: Father of cop slain in NYC shooting had stroke when he was told

16:40 , Oliver O'Connell

The father of slain NYPD officer Didarul Islam, who was killed in Monday’s horrifying shooting at a Midtown Manhattan office building, suffered from a stroke after learning the news of his son’s death, according to a report.

Isabel Keane reports.

Third victim identified, report says

16:35 , Oliver O'Connell

Julie Hyman was killed on the 33rd floor of the office tower, where she worked for Rudin Management as an associate.

She graduated from Cornell in 2020.

The three other victims were all shot in the lobby of the building. They have been identified as NYPD officer Didarul Islam, Blackstone executive Wesley LePatner, and the third is believed to be a security guard who has not yet been named.

Gunman Shane Tamura’s intended target was the NFL offices in the building, according to Mayor Eric Adams. He took the wrong elevator and ended up in the Rudin offices instead, where he opened fire again before turning the gun on himself.

A statement from the Rudin family, which owns 345 Park Avenue, said that a “cherished Rudin colleague” was among those killed in the shooting on Monday. It did not name the victim.

“The Rudin family and everyone at our company are devastated by yesterday’s senseless tragedy,” the statement said, thanking the police and other emergency responders as well as the mayor.

“The building will remain closed today as the authorities continue their investigations. As New Yorkers, we stand shoulder to shoulder in the face of this hatred, we grieve with the families and loved ones of those lost, and we pray for the full recovery of those injured.”

Shooting occurred in heart of Manhattan's financial sector

16:25 , Oliver O'Connell

Monday's shooting caused a significant shutdown across Midtown Manhattan, forcing employees at major financial firms, including hedge fund Citadel and investment bank Jefferies Financial Group Inc., into lockdown.

The disruption highlighted Park Avenue's growing prominence as the city’s financial centre, now housing more leading institutions than Wall Street itself.

JPMorgan Chase & Co.’s massive new headquarters at 270 Park Avenue is situated just blocks from 345 Park Avenue, where Blackstone is based.

Security arrangements under scrutiny following shooting at high-rise office tower

15:56 , Oliver O'Connell

The offices of investment firm Blackstone and KPMG at 345 Park Avenue are closed following last night’s tragedy.

The shooting, which claimed the lives of four victims in addition to the gunman, has raised questions about security protocols in similar high-rise office buildings.

Most financial firms' offices throughout New York have security desks, with many restricting elevator usage to those with security passes; however, lobby access is less restricted. That may change in the aftermath of this incident. Rudin Management, which owns the building, did not immediately respond to a request for comment on possible changes when asked by Reuters.

After opening fire in the lobby, the shooter, Shane Tamura, accessed an elevator that took him to the 33rd floor of the building, where Rudin’s offices are located. He shot another person there before turning the gun on himself.

A Goldman Sachs spokesperson told Reuters that the company has “robust security protocols” throughout its buildings and is “constantly assessing their effectiveness to ensure they reflect best practices, especially based on recent events.”

Blackstone CEO Stephen Schwarzman and President Jon Gray wrote a note to staff on Monday calling the day the “worst day in the firm's 40-year history,” according to sources who saw the memo.

Wesley LePatner, the firm’s global head of Core+ Real Estate and chief executive officer for Blackstone Real Estate Income Trust, was one of the four victims of the gunman.

Later on Tuesday morning, Blackstone will hold a Zoom call, sources familiar with the matter told Reuters.

Photos show desperate attempt to barricade offices in midst of shooting

Photos obtained by New York’s ABC7 show the moment Blackstone employees barricaded the door to their office with couches and other furniture as gunman Shane Tamura stalked their building.

The barricade reaches the ceiling in an effort to stop any access to that floor of the building.

After opening fire in the lobby of the skyscraper at 345 Park Avenue, Tamura, whose intended target was believed to have been the NFL offices, took an elevator to the 33rd floor, where he turned the gun on himself.

Rep. Jerry Nadler, who represents Midtown Manhattan in Congress, tweeted: “Gun violence in this country is an epidemic. The tragic loss of a brave police officer and innocent civilians is far too common.”

The Democrat lawmaker continued: “From Columbine to Sandy Hook, from the Tree of Life synagogue to the Pulse nightclub, from Charleston to today’s shooting in Midtown Manhattan, we must put an end to the easy access to weapons of war that continue to take innocent lives.”

New York governor calls for national assault weapon ban

15:20 , Isabel Keane

New York Gov. Kathy Hochul called on Congress to pass a nationwide assault weapons ban after a gunman opened fire in a Manhattan office, killing four people.

Hochul noted that while New York has some of the strongest gun laws in the country, the gunman was still able to bring the weapon across state lines and kill innocent people.

“Our laws only go so far when an AR-15 can be obtained in a state with weak gun laws and brought into New York to commit mass murder,” Hochul said in a statement.

“The time to act is now. The American people are tired of thoughts and prayers. They deserve action. Congress must summon the courage to stand up to the gun lobby and finally pass a national assault weapons ban before more innocent lives are stolen,” she said.

Gunman intended to go to NFL offices but went to wrong floor, mayor says

12:48 , James Liddell

New York Mayor Eric Adams said that mass shooting suspect Shane Tamura intended to go to the NFL offices on the lower floors of the Park Avenue office building.

Speaking on Fox 5’s Good Day New York this morning, Adams said that he “appeared to have gone to the wrong floor.”

After opening fire in the building’s lobby, Tamura allegedly took an elevator up to the 33rd floor, where he continued firing rounds.

“There are two different elevator banks,” he continued. “Some banks don’t go to every floor. He appeared to have gone to the wrong bank, and he ended up on the floor of Rudin Management.”

It comes after reports that investigators found a note in Tamura’s pocket sharing grievances with the NFL and claiming that he suffered from chronic traumatic encephalopathy (CTE).

“Terry Long football gave me CTE and it caused me to drink a gallon of antifreeze,” the piece of paper read, according to CNN. “You can’t go against the NFL, they’ll squash you.”

The motivations behind the attack were not immediately clear.

The suspected shooter Shane Tamura was a talented football player during his high school days, former teammates have said.

On the field, the Tamura was considered an “elusive” running back, former Granada Hills Charter School coach Walter Roby told NBC News.

Caleb Clarke, a former classmate and high school football teammate, played with Tamura at a Santa Clarita high school before he transferred to Grenada Hills.

He told NBC News that Tamura “was the biggest goofball in the world, just a ton of energy, class clown.”

Clarke said he didn’t recall Tamura being a troublemaker in school.

“You never would have thought violence was something you’d associate with him,” he said.

Just hours before four people were shot dead inside 345 Park Avenue on Monday evening, police said that Shane Tamura arrived in Manhattan.

The 27-year-old shooting suspect drove his BMW an estimated 2,500 miles across the country over several days after leaving his home in Las Vegas, Nevada, on Saturday.

Police Commissioner Jessica Tisch told reporters Monday that Tamura’s car passed through Colorado on Saturday, then Nebraska and Iowa on Sunday before arriving in New York City on Monday.

It was not clear why Tamura was in New York City or what had motivated him to open fire inside the building, home to the offices of several high-powered companies, including the investment giant Blackstone, the NFL and accounting firm KPMG.

Chris Raia, the assistant director in charge of the FBI’s New York field office, vowed to bring the “full force” of the agency in the probe into Monday’s shooting in Midtown Manhattan.

“You have the full force of FBI New York and full force of FBI to get to the bottom of the answers,” he told reporters on Monday.

NFL Commissioner Roger Goodell said an NFL employee was seriously injured in the Park Avenue mass shooting.

“As has been widely reported, a gunman committed an unspeakable act of violence in our building at 345 Park Avenue. One of our employees was seriously injured in this attack. He is currently in the hospital and in stable condition,” he wrote in a message to employees.

NFL staff were at the hospital supporting the worker’s family, he said.

Goodell added he believes that all other employees “are otherwise safe and accounted for.”

Hochul and Adams among New York officials remembering slain NYPD officer

10:30 , James Liddell

Top New York officials have paid tribute to NYPD officer Didarul Islam, who was shot dead during Monday’s mass shooting in Midtown Manhattan.

“Officer Didarul Islam represented the very best of New York,” Governor Kathy Hochul wrote on X late on Monday. “An immigrant from Bangladesh, he joined the NYPD to protect his city — and gave his life doing so.”

New York City Mayor Eric Adams tweeted that Didarul “represented the best of New York City, an immigrant from Bangladesh who put on a uniform to protect and serve us all.”

New York City Police Commissioner Jessica Tisch wrote: “May Police Officer Didarul Islam’s memory be a blessing.”

House Minority Leader Hakeem Jeffries said he is “praying hard for the brave NYPD officer impacted and all other victims of this tragedy.”

GOP congressman Mike Lawler tweeted: “I’m devastated by the senseless killing of an NYPD officer and innocent civilians in Midtown.”

Tamura had 'documented mental health history'

10:20 , James Liddell

Shane Tamura, who police identified as the Park Avenue mass shooter, had a “documented mental health history,” Police Commissioner Jessica Tisch told reporters on Monday evening.

It was not immediately clear whether that played a role in the incident and police are working to understand why he targeted the office block.

Shane Tamura was 'elusive' on high school football field

09:56 , James Liddell

The gunman accused of killing at least four people inside a sprawling Park Avenue office block, home to offices for the NFL, was a talented high school football player, according to his former coach.

Tamura, 27, transferred to Granada Hills Charter School in Granada Hills, a neighbourhood in Los Angeles, in 2015 when he was a senior, a former classmate told NBC News.

Former coach Walter Roby told the news station that Tamura was “a great” running back who was “real elusive, real agile.”

“He came in, worked hard, kept his nose down,” Roby said.

Anthony Michael Leon, Tamura’s former teammate at Granada Hills, said that he was shocked to learn of Monday evening’s mass shooting.

“I’m telling you, this was one of those kids who never exerted bad energy or a negative attitude,” Leon said.

Police said the motivations behind the attack are not immediately clear.

Note reportedly found on gunman details anger at NFL and claims of CTE

09:35 , James Liddell

In Shane Tamura’s pocket, investigators say they allegedly found a note claiming that he suffered from chronic traumatic encephalopathy (CTE), a disease linked to head trauma, and asked that his brain be studied, a source told CNN.

In the note, he allegedly expressed grievances against the NFL – which has its headquarters in the building he attacked – and requested that his brain be studied.

“Terry Long football gave me CTE and it caused me to drink a gallon of antifreeze,” it read, according to CNN. “You can’t go against the NFL, they’ll squash you.”

Former Pittsburgh Steelers lineman Terry Long was diagnosed with CTE. The former football player died by suicide after drinking antifreeze in 2005.

“Study my brain please I’m sorry Tell Rick I’m sorry for everything,” the note reportedly said.

Blackstone executive among four dead: report

09:22 , James Liddell

After storming the Park Avenue skyscraper on Monday, suspect Shane Tamura immediately opened fire on NYPD officer Didarul Islam, before a volley of gunfire struck others, police said.

Among those killed was an executive at investment giant Blackstone who was shot in the lobby, sources told the Wall Street Journal.

Other Blackstone employees are in the hospital receiving treatment, one source said.

Blackstone employees shared messages over email that there was a shooter in the lobby, an employee told the Journal, warning each other not to go downstairs. Others barricaded themselves in offices and bathrooms, they added.

Who is Didarul Islam? The NYPD officer killed in Midtown Manhattan shooting

09:14 , James Liddell

New York City Police Department officer Didarul Islam was among four people gunned down in Monday evening’s shooting at the 345 Park Avenue office tower, officials say.

The 36-year-old Bangladeshi national had been off-duty, but working a private security job in the building when he was shot dead by suspect Shane Tamura, NYPD Commissioner Jessica Tisch said at a Monday press conference.

“He put himself in harm’s way, he made the ultimate sacrifice – shot in cold blood, wearing a uniform that stood for the promise that he made to this city,” she said.

“He died as he lived, a hero.”

Didarul had served in the NYPD’s 47th precinct in the Bronx for three and a half years, New York City Mayor Eric Adams told reporters.

Adams met with Islam’s family earlier Monday night and told them that “he was a hero and we admire him for putting his life on the line.”

Islam leaves behind his pregnant wife and two young sons.

Suspected gunman Shane Tamura is accused of opening fire in a Midtown Manhattan office building in New York City on Monday evening and killing four people, including a New York police officer, before turning the gun on himself.

“I want to extend my profound sympathies to all of the victims and their families, and to the brave NYPD cops who today lost a brother,” NYPD commissioner Jessica Tisch said a press conference on Monday evening.

Here's what to know about the shooting

08:44 , James Liddell

A New York City police officer and at least three others have been killed after a gunman entered a Midtown Manhattan office building and opened fire, according to officials.

Police said the gunman, who is now dead from a self-inflicted wound, was identified as Shane Tamura, a 27-year-old from Las Vegas.

Tamura is accused of strolling into the Manhattan skyscraper carrying an M4 assault rifle by his side on Monday at around 6:30 p.m and “spraying” ammunition inside the building’s entrance.

New York City Police Commissioner Jessica Tisch said Tamura exited a black BMW and walked toward the building’s entrance carrying the assault rifle. A loaded revolver, ammunition and magazines were found in the car, according to officials.
