John A. Rothrock Jr., 63, retired chief judge of Fairfax General District Court and a former basketball coach at Arlington's Washington-Lee High School, died March 1 after a heart attack at his farm in Amissville in Rappahannock County, Va.

Judge Rothrock had served 26 years on the General District Court when he retired in 1980. Before he was named to the bench in 1954, he was a teacher and coach at Washington-Lee High School for five years, a period in which his teams won 80 games while losing 18 and captured a Northern Virginia championship.

His service at General District Court coincided with a period of explosive growth in Fairfax County, and at his retirement it was the busiest court in Northern Virginia, with seven judges and about 20,000 cases a year.

It had jurisdiction over misdemeanors, traffic offenses, civil suits up to $5,000 and preliminary hearings on felony charges and it was often called Fairfax County's court of first resort.

During his years on the bench, Judge Rothrock presided over hundreds of cases involving the likes of shoplifters, vandals, wife beaters, weekend drunks, violators of zoning ordinances and people unable or unwilling to control their dogs.

During the 1950s, he also served two days a week as judge of the Juvenile and Domestic Relations Court, hearing up to 35 cases a day. In 1962, Judge Rothrock reorganized the court to establish separate divisions for juvenile and traffic cases.

Judge Rothrock was a former president of the Municipal and County Court Judges Association of Virginia. In 1972, he received an achievement award from the Fairfax County Council on Alcoholism for establishing a counseling program for drunk drivers.

A native of Monticello, Ind., Judge Rothrock served in the Navy during World War II. A graduate of Northwestern University, he received a degree in business administration from Purdue University. He moved to this area in 1948 and taught and coached basketball at Mount Vernon High School for one year before he became basketball coach at Washington-Lee.

While teaching and coaching at Washington-Lee, he attended George Washington University Law School at night, and passed the D.C. bar exam one year before receiving his law degree. He was named a judge shortly after completing law school.

In 1966, Judge Rothrock was named "Man of the Year" by the Fairfax City Chamber of Commerce. He was a former director of the National Bank of Fairfax, a Mason and a member of the Fairfax United Methodist Church.

A former resident of Fairfax City, Judge Rothrock moved to Amissville upon his retirement, and then traveled extensively in Mexico and the American Southwest.

His marriage to the former Ann Farr ended in divorce.

Survivors include his wife, Nancy Rothrock, and one son by his second marriage, Sid Rothrock, both of Amissville; one son by his first marriage, Dr. John Rothrock of San Diego, and two brothers, Joe Rothrock of Albuquerque, and Judge Thomas Rothrock of Fairfax.
