Incident
Police Officer William Chisolm was shot and killed during an altercation while off-duty.

An argument ensued, resulting in a physical altercation. During that altercation, the suspect was able to gain control of Officer Chisolm's service revolver and fire one shot, striking Officer Chisolm in the head. Officer Chisolm was taken to Lincoln Hospital, where he died from his wound several hours later. The 19-year-old suspect fled the scene, but later surrendered himself to police.

Officer Chisolm had served with the New York City Police Department for three years.
