Police Fire on Knife-Wielding Perpetrator After Fatal Stabbing

New York Police Commissioner Jessica Tish said officers were forced to use lethal force when a knife‑wielding attacker refused to drop her weapons and continued to pose a threat to bystanders. The suspect, identified as Pamela Sisneros, had previously been involved in a separate knife assault that left another person injured. The investigation so far shows no terrorist motive, but points toward possible mental‑health factors.
