Police say this stemmed from an argument between two women that spiraled out of control.
The deadly incident was caught on camera.
Video shows a group of people with two children nearby walking down the street.
Just a few moments later, the woman at the center of the police hunt can be seen.
She walked up to the 22-year-old woman and a fight broke out.
As the fight ensued, the young woman was stabbed multiple times as onlookers stood by.
The street where the victim took her final breath turned into a crime scene.
It is still unclear what led up to the heightened situation around 10:15 Tuesday night, which unfortunately got out of control on West 40th Street.
The woman who was stabbed in the chest died at the hospital.
She was later identified as Jordin Walston, 22, of Morningside Heights.
Walston was with her boyfriend at the time of the deadly confrontation.
For New Yorkers and tourists, they say this isn't the city they once knew.
"The city is unsafe. But it's not like it used to be. I mean before we did have crime obviously but not to this magnitude. It's overpopulated with homelessness (and) mental health issues so it gets chaotic. One argument to another and then it leads to this," Juan Hernandez, New York resident, told Eyewitness News.
Police described the suspect as a woman wearing a white shirt and blue jeans, that got away down 8th Avenue.
