The attack unfolded shortly after 4:24 p.m. local time on Monday along Seventh Avenue in Times Square, one of New York City's busiest tourist hubs. NYPD Commissioner Jessica Tisch described the incident as "an unprovoked double stabbing" that occurred within approximately 20 seconds.
According to preliminary information provided by police, the suspect approached a man who had just exited a subway station and was waiting with his wife to cross the street. A witness reported seeing the woman remove two knives from a red Target bag before stabbing the 68-year-old man in the right side of his abdomen. The suspect then stabbed Erin Piacenti before officers intervened.
Mayor Mamdani thanked NYPD officers for stepping in and "prevented a horrific attack from becoming even worse." All three individuals were taken to hospital, where both Piacenti and the suspect were pronounced dead. The second victim is now listed as stable at Bellevue Hospital.
Piacenti's employer, Bank of America, confirmed her role as a vice president. The attack has drawn widespread attention due to its location in Times Square and the unprovoked nature of the violence during peak afternoon hours. Authorities have not yet released the suspect's identity or a possible motive, but the investigation is ongoing.
