Shocking Times Square Rampage: Mentally Ill Mom Who S.t.a.b.b.e.d Bank Exec to Death Was Battling Bipolar Disorder, Divorce, and Years of Estrangement From Her Daughters
A random and unprovoked stabbing spree in the heart of Times Square on Monday afternoon left one woman dead, another man wounded, and the attacker herself fatally shot by police, exposing a long and painful struggle with mental illness that family members say had defined her life for decades.
Around 4:24 p.m. on August 31, 2026, 49-year-old Pamela Cisneros of Queens pulled two kitchen knives from a red Target shopping bag near West 41st Street and Seventh Avenue. Within roughly 20 seconds she stabbed a 68-year-old man from Rhode Island in the abdomen as he waited to cross the street with his wife, then continued north and fatally stabbed 32-year-old Erin Piacenti, a Bank of America vice president who had just returned from five months of maternity leave after the birth of her daughter. Both victims were rushed to Bellevue Hospital. Piacenti was pronounced dead; the man remains in stable condition.
Police confronted Cisneros near West 43rd Street. Body-camera footage captured a roughly four-minute standoff in which officers repeatedly ordered her to drop the knives. She refused, telling them she would rather kill them than surrender the weapons, and advanced while brandishing a knife in each hand. Multiple Tasers proved ineffective. Two officers then fired, striking her. She was pronounced dead at the hospital.
Family members described a woman whose life had been marked by severe mental health challenges long before the attack. Her brother, Patrick Peralta, said Cisneros was diagnosed with bipolar disorder about ten years ago after suffering postpartum depression following the birth of her second child roughly a decade earlier. She had three daughters. The eldest and youngest lived in Florida with their father and had been estranged from her for years because of her earlier struggles. Her middle child, who is non-verbal and has severe autism, lives in a care home in Brooklyn. Cisneros had tried for years to raise the children but eventually could no longer cope.
Relatives said she had been going through a difficult divorce that stretched over several years and was only recently finalized. She worked intermittently in human resources, attended church daily, and had studied psychology. After a suicide attempt in 2019 in which she tried to jump in front of a subway train, she began receiving monthly psychiatric injections and appeared more stable in recent years. Family members expressed shock that she had never previously shown violence toward others.
The case has renewed public discussion about the limits of community mental-health treatment, the difficulty of ensuring consistent medication adherence, and the challenges facing families when a loved one lives with serious psychiatric illness. Cisneros had documented prior interactions with police related to mental health in 2018 and 2019 but no criminal record. Investigators continue to examine what may have triggered the sudden and violent break on Monday.
The tragedy claimed a promising young professional and new mother in the middle of a crowded tourist district and left a family in Queens devastated by the loss of a sister and daughter they believed was finally finding stability. It also left the city confronting once again how a person in crisis can move through one of the world’s busiest public spaces until the moment of irreversible violence.
