A series of unprovoked knife attacks across Manhattan has left three people dead, including two men and one woman, with a suspect now in custody. The incident, described by city officials as a deadly spree, has raised concerns about the failures of the criminal justice and mental health systems. The accused, a 51-year-old man with a significant criminal history, was released from jail just a month before the attacks. He faces charges of first-degree murder for the violent incidents that occurred in multiple locations throughout the city.
