Pamela Cisneros, a 49-year-old mother of three from Queens, walked into one of New York’s busiest tourist hubs on a Monday afternoon carrying two kitchen knives in a red Target bag. Within minutes, she had stabbed two strangers in random, unprovoked attacks near Times Square, killing one and wounding the other, before being fatally sH๏τ by police.

The sequence unfolded with shocking speed. Around 4:24 p.m. near West 41st Street and Seventh Avenue, Cisneros approached a 68-year-old man from Rhode Island who had just exited the subway with his wife. She pulled the knives from the bag, waved them, and stabbed him in the abdomen. He survived and was later listed in stable condition. Roughly 20 seconds later, a block north near West 42nd Street, she stabbed 32-year-old Erin Piacenti, a Bank of America vice president from New Jersey, also in the abdomen. Piacenti was pronounced ᴅᴇᴀᴅ at Bellevue Hospital.

Officers located Cisneros shortly afterward near an NYPD substation on West 43rd Street. Body-camera footage and witness accounts show a roughly four-minute confrontation in which she repeatedly refused commands to drop the weapons. She told officers she would rather kill them than surrender the knives and advanced while swinging both blades. Multiple officers deployed Tasers without effect. Two then fired their service weapons, striking her. Cisneros was taken to Bellevue, where she was pronounced ᴅᴇᴀᴅ. The knives were recovered at the scene. Police described the stabbings as random and unprovoked. Cisneros had no prior criminal arrests with the NYPD but carried a documented history of mental-health encounters in 2018 and 2019.

Family members later painted a more complex picture of the woman behind the attack. Her brother, Patrick Peralta, 59, said Cisneros had struggled for years with what he believed was bipolar disorder, alongside earlier postpartum depression after the birth of her second child. She had attempted suicide years earlier by trying to jump in front of a subway train in Queens. In recent years she received monthly medication injections and appeared more stable. She had told relatives she felt fine as recently as the Saturday before the incident. Peralta last saw her in person in early August at a family gathering for their stepfather’s birthday. He said she had never previously shown aggression or violence toward others and expressed complete shock at the sudden change.

Cisneros’s father, Mario Cisneros, noted that she had lived with serious mental-health challenges for decades and that he had believed she was improving, though she had recently stopped attending some appointments with him. Court records and family accounts also indicate periods of personal upheaval, including a divorce and time spent in Florida with her children before returning to New York. Neighbors and social-media posts from earlier periods reflected an uneven life—sometimes troubled, sometimes quieter—before the sudden violence in Midtown Manhattan.

The episode has renewed attention on the challenges of managing long-term mental illness in a dense urban environment. Cisneros lived in Woodside, Queens, and had been receiving treatment that relatives believed was keeping her symptoms under control. Yet on that Monday afternoon the system that had previously contained her struggles failed to prevent a rapid, lethal break. Police responded according to their training once the threat escalated, ending the immediate danger after the two stabbings. The surviving victim recovered; the family of Erin Piacenti was left grieving a young professional whose life ended in an unprovoked attack on a crowded sidewalk. Officials continue to review the full circumstances, including body-camera evidence and Cisneros’s medical history.

The tragedy leaves unanswered questions about warning signs that may have been missed and the limits of current mental-health support for individuals who appear stable until they suddenly are not. In the heart of Times Square, a long private battle became a public horror in less than half an hour.
