Officer David Haynes was killed in an automobile accident while involved in a vehicle pursuit of a burglary suspect.

The pursuit was traveling down Kings Highway when another car pulled out of Oleatha Avenue and collided with Officer Haynes' patrol car. The officer was transported to a local hospital where he succumbed to his injuries.

The driver who was fleeing the pursuit was subsequently captured and confessed. In September 2011 he plead guilty to second degree murder, first degree burglary, and resisting arrest by fleeing police. He was subsequently sentenced to 20 years in prison.

Officer Haynes had served with the St. Louis Police Department for only one year, and had served with the United States Marines before joining the department. He was survived by his wife.
