On July 13, Singleton was in a taxi when police say he began acting erratically while high on PCP. The cab driver called 911, and police restrained him by using a "protective body wrap."
Singleton was on his way to a nearby hospital when he went into cardiac arrest and died. Although the homicide ruling does not imply criminal activity, the medical examiner deemed the actions taken by police contributed to his death.
Police Commissioner Bill Bratton and New York City Mayor Bill de Blasio have since defended the officers' actions, insisting authorities followed police "protocol."
In the case of Singleton, no officers have been subjected to any disciplinary action.
