Malaysia Goodson, 22, fell to her death on Monday while carrying a stroller with her 1-year-old daughter down a flight of stairs at a New York City Subway station.

According to NBC New York, Goodson was found unconscious on the southbound platform at the Seventh Avenue B D E station near Times Square around 8 p.m. She had the stroller in her hands with her daughter, who was unharmed, tucked inside.

Authorities are unclear whether the fall was accidental or if it was sparked by a medical issue. Goodson's family told the news outlet they were not sure what caused the fall either. There were reportedly no signs of trauma at the scene.

The woman lived in Stamford, Connecticut, and was visiting family in New York City when she fell.

Goodson's death sparked an outcry on social media with several mothers and disabled people spotlighting the accessibility issues with the city's subway system. Protesters gathered in front of the Manhattan station on Wednesday morning to hold a vigil.

Reports from NBC said that only 25 percent of NYC subway stations have elevators and on average each one experienced outages at least 50 times a year.

Mayor Bill de Blasio criticized the MTA following reports of the woman's death.

The public transit company addressed the "heartbreaking tragedy" in a statement, which said, "The MTA, medical examiner's office and NYPD are conducting a full investigation."

Goodson's daughter has been reunited with her father and grandmother.
