Two Strangers Were Attacked in Times Square — Then Police Faced a Split-Second Decision

It began as an ordinary Monday afternoon in one of the busiest places in New York City.

Tourists were moving through Times Square. Commuters were making their way home. Cars and pedestrians filled the streets around Seventh Avenue.

Then, within seconds, everything changed.

According to police, a woman carrying two large kitchen knives attacked two people she apparently did not know. One victim would survive.

The other would not.

And within minutes, the woman accused of carrying out the attacks would also be fighting for her life.

Two Attacks Within Seconds

The violence unfolded on August 31, 2026, shortly before 4:30 p.m.

Police identified the woman as Pamela Cisneros, 49, of Queens.

According to NYPD Commissioner Jessica Tisch, Cisneros approached 68-year-old Tak Kam after he had exited the subway and was waiting with his wife to cross the street.

Police said Cisneros removed two kitchen knives from a red Target shopping bag.

She then stabbed Kam in the abdomen.

But the attack was not over.

Authorities said Cisneros continued north along Seventh Avenue and, seconds later, approached another stranger.

That person was 32-year-old Erin Piacenti of Chester, New Jersey.

She was also stabbed in the abdomen.

Police said the two apparently random and unprovoked attacks occurred within roughly 20 seconds.

Both victims were rushed to Bellevue Hospital.

Kam survived and was reported in stable condition.

For Piacenti, however, the outcome was devastating.

She was pronounced dead at the hospital.

Officers Confronted Cisneros

By then, police officers were confronting Cisneros nearby.

According to authorities, she was still holding a knife in each hand.

What followed was not an immediate shooting.

Police Commissioner Tisch said officers spent approximately four minutes ordering Cisneros to drop the weapons and attempting to persuade her to surrender them.

She did not comply, according to the police account.

Officers then attempted another option.

Three officers discharged Tasers, according to the New York Attorney General’s Office.

They appeared to have no effect.

The confrontation was approaching its final moments.

Authorities say Cisneros then moved toward the officers while she was still holding the knives.

Two officers opened fire.

Cisneros was struck and transported to a hospital, where she was later pronounced dead.

But as investigators began reconstructing what had happened in Times Square, another part of Cisneros’ story began to emerge.

Her Family Described Years of Mental Health Struggles

Cisneros had previously experienced serious mental health problems, according to relatives and authorities.

Her family told news organizations that she had received treatment and that they had not expected her to become violent.

Her father, Mario Cisneros, told The New York Times that his daughter had lived with serious mental health problems for years.

Authorities also confirmed previous police encounters connected to mental health concerns.

One particularly serious episode occurred years earlier, when Cisneros reportedly attempted to jump in front of a subway train in Queens.

Yet her family said they had not seen her as someone likely to carry out an attack like the one that occurred in Times Square.

That made what happened on Monday even more difficult for them to understand.

And after Cisneros was killed, her mother publicly questioned whether the confrontation could have ended differently.

Her Mother Questioned the Police Response

Speaking to Fox 5 New York, Cisneros’ mother questioned why officers had ultimately needed to use deadly force.

Her comments reflected the family’s grief and confusion over the death.

But the police account contains important additional context.

Authorities say Cisneros was armed with two knives, repeatedly refused commands to drop them, was not stopped by the Tasers and then moved toward officers while still holding the weapons.

Police Commissioner Tisch characterized the situation as rapidly developing and dangerous.

The officers’ actions are now subject to formal review.

An Independent Investigation Has Been Opened

On September 2, the New York Attorney General’s Office of Special Investigation announced that it had opened an investigation into Cisneros’ death.

Such an investigation does not itself mean that officers acted improperly.

Under New York law, the Office of Special Investigation assesses incidents in which a police or peace officer may have caused a person’s death.

The attorney general’s office described the facts available so far as preliminary and subject to change as the investigation continues.

That means questions surrounding the final police encounter will now be examined separately from the criminal investigation into the stabbings.

But there is another family at the center of the tragedy.

And for them, there can be no reversal of what happened.

Erin Piacenti Had Just Returned From Maternity Leave

Piacenti was a vice president at Bank of America and the mother of a five-month-old daughter.

She had only just returned to work after spending months on maternity leave.

According to reporting about her final day, she was heading home from work when she encountered Cisneros in Times Square.

There is no indication that the two women knew one another.

Police have described the attacks as random and unprovoked, and authorities have said they have found no evidence that the incident was connected to terrorism.

Piacenti’s death left behind her husband, their infant daughter and a wide circle of relatives, friends and colleagues.

Bank of America said it was shocked and deeply saddened by the loss of its colleague.

Meanwhile, Kam, the other person stabbed that afternoon, survived.

He had reportedly been visiting his son in New York and was with his wife when he was attacked.

Three Families Were Changed in Minutes

The physical violence unfolded extraordinarily quickly.

According to police, only about 20 seconds separated the two stabbings.

Yet the consequences will last far longer.

Tak Kam survived an attack that authorities say appeared to be completely random.

Erin Piacenti, a 32-year-old new mother returning to her career after maternity leave, lost her life.

Pamela Cisneros also died after the confrontation with police.

Her relatives are now mourning while also trying to understand how someone they knew as a family member became responsible, according to authorities, for an apparently unprovoked act of violence.

And the final moments of the incident remain under official scrutiny.

The New York Attorney General’s investigation will examine the circumstances surrounding Cisneros’ death, while authorities continue working to understand what led to the attacks themselves.

For now, one of the most unsettling facts is also one of the simplest.

The two victims apparently did not know their attacker.

They were simply moving through Times Square on a Monday afternoon when, within seconds, their lives changed forever.
