A woman accused of stabbing a tourist at Macy’s flagship store in New York City had been released from a psychiatric hospital just hours before the attack, prosecutors revealed. Kerri Aherne, a 43-year-old Massachusetts woman, faced charges of attempted murder and assault following the incident. She appeared in court on December 12, where she was ordered to be held without bail. Prosecutors disclosed that Aherne had been discharged from a Manhattan psychiatric ward on the morning of the attack, after a year-long stay, and had entered Macy’s with the intention of killing someone as she believed voices in her head instructed her to do so.

According to reports, Aherne purchased a knife from Macy’s and then targeted a 39-year-old woman from California in the store’s bathroom. The victim was in the midst of changing her baby when she was attacked, resulting in the baby falling from the changing table. Fortunately, the infant was unharmed during the incident. Law enforcement officers from the New York Police Department responded to the scene following a report of the assault at Macy’s Herald Square around 3:15 p.m. local time on December 11. The victim, an employee of the Los Angeles County Sheriff’s Department, sustained multiple stab wounds to her back and a laceration to her arm. She was subsequently taken to the hospital and discharged.

Aherne faced charges of attempted murder, assault, possession of a weapon, and endangering the welfare of a child. Prosecutors also revealed that Aherne had a history of mental illness, having been arrested in 2018 for threatening to kill Senator Elizabeth Warren on Facebook. Subsequently, she was deemed incapacitated, with her mother and sister appointed as guardians, and placed on a court-ordered treatment plan. Despite being released from a psychiatric facility in New York City, Aherne expressed dissatisfaction with the care received, stating her reluctance to return to such facilities.
The bail application unveiled details of Aherne’s departure from Massachusetts in 2024 while on temporary leave from the hospital, during which she made statements suggesting a preference for prison over continued hospital treatment. Aherne is set to appear in court again on December 17.
