NEW YORK (KTNV) — At least four people, including an off-duty NYPD officer, were shot and killed in Midtown Manhattan in New York City on Monday evening by a Las Vegas man, according to New York City authorities.
In total, five people were shot, with one in critical condition, said New York City Mayor Eric Adams in a press conference on Monday. Four other victims are being treated for minor injuries after attempting to flee the scene.

The suspect has been named as a Las Vegas man, 27-year-old Shane Tamura.
New York City Police Commissioner Jessica Tisch said they received calls of an active shooting around 6:28 p.m. EST.
According to authorities, surveillance video shows Tamura exiting a black BMW, carrying an M-4 assault rifle.
He proceeded to enter the commercial building and immediately opened fire. While in the lobby, the suspect allegedly shot and killed a police officer identified as 36-year-old Didarul Islam, who was working as private security. Afterwards, he would go onto the 33rd floor, where he continued opening fire and eventually would shoot and kill himself.
Authorities say Tamura has a Las Vegas address, and the car he was driving was registered in Nevada. Police in New York also discovered medication prescribed to Tamura, ammunition, a loaded revolver, magazines and a backpack.
The car traveled cross-country to New York City.
"The initial investigation shows that Mr. Tamura's vehicle traveled cross-county through Colorado on July 26, then Nebraska and Iowa on July 27, and then in Columbia, New Jersey as recently as 4:24 p.m. today. The vehicle entered New York City shortly thereafter," said Tisch.
New York authorities say that law enforcement in Las Vegas stated that Tamura has a documented mental health history.
According to CNN, Tamura had a concealed weapons permit, but did not have a significant criminal background.
Channel 13 searched court records on Tamura and found that he faced trespassing charges for an incident in 2023, but the case was later dismissed by the DA's office, according to court records.
His motives are still under investigation. It is unclear why Tamura targeted the commercial building at 345 Park Avenue.
According to authorities, they believe that Tamura is a lone shooter and there is no longer an active threat to the public.
"There's still many questions that we have to answer, and we will answer them, but for now, our city is in mourning for the innocent lives lost. May their memories be a blessing," said Tisch.
Channel 13 sent crews out to the address believed to belong to Tamura.
Channel 13 will continue providing updates.
