One person died and five others were injured in a parking lot collapse in lower Manhattan on Tuesday. The incident occurred near Ann Street and Nassau Street, not far from the New York Stock Exchange and Pace University, and officials have stated that foul play is not suspected.

Firefighters were the first to search for casualties, but they were forced to withdraw due to the unstable conditions of the collapsed structure. Emergency workers then used robotic devices to search the site, and all victims are believed to have been accounted for.

Police Commissioner Keechant Sewell told reporters that the collapse was likely due to a structural failure. The New York City Fire Department used drones for the first time to search for casualties, as the situation was extremely dangerous for firefighters still inside the building.

According to Chief of Fire Operations John Esposito, six people were in the parking structure at the time of the incident. The identity of the deceased has not been released.

The parking structure is used by Pace University students, faculty, and staff, and the campus was evacuated as a precaution. New York City Mayor Eric Adams described the building as “completely unstable.” Online records from the state’s Department of Buildings show that the structure had 45 violations, 25 of which were issued since 2003. Many of the violations were related to elevators, and one 2003 filing noted cracks in the structure’s ceiling slabs and “defective concrete with exposed rear cracks.”

Eyewitnesses reported that the collapse occurred suddenly, with some seeking refuge in nearby businesses. Sandy Imhoff, who lives in an adjacent apartment, fled her home when the building began shaking. She was concerned about her cats but relieved that everyone in her building could evacuate safely.
