The woman who fatally stabbed a young Bank of America executive in the middle of Times Square last week had struggled with mental health problems for much of her adult life, her brother told the New York Post, painting a picture of a family that watched a mother of three spiral without adequate intervention for years.
Pamela Cisneros, 49, of Queens, was shot and killed by police after she allegedly stabbed two people near the heart of Manhattan's busiest tourist corridor, then charged at officers with two kitchen knives. One of her victims, 32-year-old Erin Piacenti, a Bank of America vice president from Chester, New Jersey, did not survive.
The attack has renewed hard questions about how New York City handles mentally unstable individuals who cycle through police encounters without ever being arrested or committed, and whether the city's legal and mental health systems are failing both the public and the people they claim to protect.
Cisneros's brother described her as a woman who had battled possible bipolar disorder and other mental health challenges for years. He told the Post that her condition had worsened over time and that the family had witnessed her deterioration without being able to force her into sustained treatment.
She was a mother of three. Her brother's account suggests that her struggles were not hidden from the people around her, and that the violence in Times Square did not erupt from nowhere.
The portrait that emerges is one familiar to families across the country: a relative whose behavior grows more erratic, whose contact with authorities produces paperwork but no lasting intervention, and whose crisis ultimately lands on strangers.
The stabbing took place in one of the most heavily policed patches of real estate in the United States. Times Square sits within steps of an NYPD substation. Officers responded quickly, but not before Cisneros had already plunged a knife into Piacenti and stabbed a 68-year-old man, who was later reported in stable condition.
When officers confronted Cisneros, she refused to drop her weapons. Police Commissioner Jessica Tisch told reporters that Cisneros said she would not put anything down and "would rather kill" the officers. Police then fired, fatally striking her. Officers provided first aid afterward, but Cisneros died from her injuries.
The 68-year-old male victim's identity has not been publicly released. His condition was listed as stable.
The woman who lost her life was not a tourist wandering through Times Square on a whim. Erin Piacenti was a vice president of business selection and conflicts at Bank of America, a role that placed her squarely in the professional class of young New Yorkers who move through the city every day trusting that its public spaces are safe enough to walk through.
She was 32 years old and lived in Chester, New Jersey. The Washington Examiner identified Piacenti as the deceased victim, drawing on details about her professional background and personal life.
Bank of America released a statement after her death:
"We are shocked and deeply saddened by the tragic loss of our colleague. She was a valued teammate who will be greatly missed. Our hearts go out to her family and all of her loved ones."
Piacenti's killing turned a routine walk through one of the world's most famous intersections into a crime scene, and her family's loss into a symbol of a broader public safety failure.
Cisneros had prior mental-health-related encounters with police. Newsmax reported that those contacts occurred in 2018 and 2019. Despite those encounters, she had no arrest record in New York City.
That gap between contact and consequence sits at the center of a recurring debate in the city. Officers interact with a person in crisis. Reports get filed. The individual returns to the community. No charges follow. No involuntary commitment is pursued, or if it is, it does not stick. Then something catastrophic happens.
New York's legal framework for involuntary psychiatric holds requires a showing that a person poses an imminent danger to themselves or others. Civil liberties advocates have long defended that high bar. But cases like this one force the public to ask whether the bar is calibrated to protect the right people.
The Times Square stabbing was not even the first fatal knife attack in that location this year. Newsmax noted that a man was fatally stabbed in the same area in May. Two deadly stabbings in roughly four months, in a zone saturated with police presence and surveillance cameras, suggest that the problem is not a lack of officers on the ground.
It suggests something deeper: that individuals in severe mental health crises are moving through public spaces with weapons, and that the systems designed to intercept them before violence are failing at a basic level.
Authorities have not publicly confirmed what triggered Cisneros's attack or whether she targeted Piacenti specifically. Investigators have not said whether Cisneros was receiving any mental health treatment at the time of the stabbing, or whether she had been evaluated or released from any facility in the weeks before the attack.
The NYPD has not disclosed whether Cisneros made any statements about her intentions before the stabbing began. Her brother's account of a long mental health struggle raises the question of whether any agency, hospital, or court had an opportunity to intervene and did not.
Those facts will matter as the city reviews what happened and whether any systemic change follows.
Cisneros is dead. Piacenti is dead. A 68-year-old man is recovering from stab wounds. And the city's mental health infrastructure, which has absorbed billions in funding over the past decade, produced a woman with documented police contacts who walked into Times Square with two kitchen knives and killed a stranger.
The officers who responded did their jobs. They confronted an armed attacker, gave clear commands, and used lethal force only after Cisneros refused to disarm and threatened to kill them. The failure did not happen in those seconds. It happened in the years before them.
A family knew. Police had prior contact. And still, nothing in the system stopped Pamela Cisneros from reaching Times Square with a pair of knives and the intent to use them.
When the institutions trusted to keep dangerous people off the streets cannot do that, the cost is not abstract. It is a 32-year-old woman who will not come home.
