Richard J. Daronco was appointed by President Ronald Reagan to the United States District Court for the Southern District of New York.

In April 1988, Judge Daronco presided over a bench trial in a sex discrimination and sexual harassment case, in which the plaintiff represented herself. On May 19, 1988, Daronco issued a written decision holding in the defendant employer's favor and dismissing the case.

On May 21, 1988, Charles L. Koster, a retired New York City police officer and the father of the unsuccessful plaintiff, shot and killed Judge Daronco while the judge was doing yardwork at his home. Koster then committed suicide.
