A sudden knife attack cut through the afternoon congestion of Times Square on Monday when a woman armed with two large knives stabbed two strangers within seconds of one another, killing a 32-year-old New Jersey woman and seriously injuring a 68-year-old man before police shot and killed the suspected attacker.
The violence began shortly after 4:20 p.m. Aug. 31 near West 41st Street and Seventh Avenue, an intensely traveled section of Midtown Manhattan where subway passengers emerge directly into dense pedestrian traffic. Police identified the suspected attacker as Pamela Cisneros, 49, of Queens, and said the preliminary investigation has uncovered no relationship between her and either victim.
The first victim, a 68-year-old Rhode Island man, had recently exited the subway and was waiting with his wife to cross Seventh Avenue. Investigators determined that Cisneros removed two knives from a shopping bag before approaching the man and stabbing him in the right side of his abdomen.
The injured man was transported to Bellevue Hospital with wounds initially considered life-threatening. By Tuesday, authorities reported that his condition had stabilized. His identity had not been publicly released. Investigators found no evidence of an argument, confrontation or previous contact between the man and Cisneros before he was attacked.
Cisneros continued north along Seventh Avenue, reaching the vicinity of West 42nd Street within seconds. There she encountered Erin Piacenti, 32, of Chester, New Jersey. Police said Piacenti was stabbed in the abdomen approximately 20 seconds after the first victim was wounded.
Piacenti was rushed to Bellevue Hospital, where she died from her injuries. She worked as a vice president within Bank of America’s global corporate and investment banking operations. Her identity was publicly confirmed Tuesday following notification of her family.
The speed of the two attacks initially created some confusion surrounding the duration of the episode. The 20-second period described by authorities refers to the interval separating the two stabbings, not the entire confrontation. Cisneros remained armed afterward and continued north through Times Square, extending the incident for several additional minutes.
Witnesses alerted nearby NYPD officers as Cisneros approached the area between West 42nd and West 43rd streets. The confrontation developed only a short distance from the NYPD substation near One Times Square, placing numerous officers within immediate reach of an armed suspect moving through one of the most densely occupied public spaces in the country.
Police surrounded Cisneros while she continued holding a knife in each hand. Officers spent approximately four minutes directing her to surrender the weapons. She refused and threatened the officers while maintaining possession of both knives.
Multiple officers then deployed Tasers in an attempt to incapacitate her. The devices failed to stop her movement. Police said Cisneros advanced toward officers while continuing to wield the knives, at which point two officers fired their service weapons.
Cisneros was struck and fell to the pavement. Officers secured her, placed her in handcuffs and administered emergency medical assistance before she was transported to Bellevue Hospital. She was later pronounced dead.
Both knives were recovered by investigators. Portions of the confrontation were recorded by witnesses on cellphones, while police body-worn cameras captured the officers’ encounter with Cisneros. The NYPD has announced that the body-camera recordings will be released after the investigative process permits public disclosure.
The department’s Force Investigation Division is examining the fatal police shooting, including the officers’ attempts to obtain Cisneros’ surrender, the deployment of Tasers and the circumstances immediately preceding the gunfire. Investigators are separately reconstructing Cisneros’ activities before the first stabbing and attempting to determine why she was carrying the knives in Times Square.
Police records show Cisneros had no previous NYPD arrest history. Authorities disclosed that the department had documented two earlier mental-health-related encounters involving her, one in 2018 and another in 2019. Officials have not released the underlying circumstances of those encounters, and investigators have not established that they explain Monday’s attack.
No motive had been identified by Tuesday. Investigators have described the two victims as strangers to Cisneros and have found no evidence that either was selected because of a personal connection, dispute or identifiable association. Authorities have also reported no evidence linking the attack to terrorism.
The location magnified both the danger and the scale of the police response. Times Square carries enormous pedestrian volumes throughout the day, combining subway passengers, tourists, office employees, theater patrons, street vendors and residents within several closely packed blocks. The stabbing occurred during the afternoon while the surrounding sidewalks and intersections were heavily occupied.
Seventh Avenue was partially closed while detectives documented the scene, recovered physical evidence and reviewed available recordings. Police activity remained concentrated around the area for hours before traffic restrictions were removed.
Monday’s homicide was the second fatal stabbing reported in Times Square during 2026. A separate stabbing death occurred in the district in May, although authorities have identified no connection between the incidents. The killings have occurred against a broader decline in New York City homicides this year, with the city recording substantially fewer killings than during the corresponding period of 2025.
For investigators, the remaining questions extend beyond the sequence already captured by cameras and witnesses. Detectives are examining Cisneros’ movements before she reached Seventh Avenue, how long she had possessed the knives, what brought her to Times Square and whether additional evidence can establish what preceded the first attack.
What has been established is a compressed sequence of violence across several blocks of Midtown Manhattan: a man stabbed while standing beside his wife, a second stranger attacked approximately 20 seconds later, an armed suspect continuing through crowded streets and a prolonged police confrontation that ended only after Tasers failed and officers opened fire.
Piacenti died at 32. The 68-year-old victim remained hospitalized in stable condition Tuesday. Cisneros, 49, also died at Bellevue Hospital, leaving detectives to reconstruct the circumstances behind an attack that began without an apparent dispute and ended minutes later with two people dead in the center of Times Square.
