Malaysia Goodson, 22, of Stamford, Connecticut, fell in the Seventh Avenue subway station, at 53rd Street, about 8 p.m., officials said. She was unconscious and unresponsive when officers arrived.
She was taken to a nearby hospital, where she was pronounced dead, police said.
Goodson’s 1-year-old daughter, who was not identified, was found conscious and treated at the scene. She was reunited with her father and grandmother.
The Seventh Avenue station where Goodson fell does not have an elevator. The Metropolitan Transportation Authority, which operates the subway, did not respond immediately to a request for comment.
It was not clear whether she suffered from a medical condition or if she was killed from the impact of the fall. An investigation into her death was ongoing Tuesday, police said.
The city’s medical examiner will determine what caused Goodson’s death, officials said.
