John T. Reges, 62, a Washington attorney who specialized in criminal law and who was the owner of the Old Angler's Inn in Potomac, died Monday at Sibley Memorial Hospital. He had cancer.

Born and reared in Washington, Mr. Reges began practicing law here in 1948 with his father, the late George H. Reges. Except for several years in the 1960s, when he represented the American Stevedore Co. in New York City, he maintained a private law practice here until his death.

In the early 1960s, Mr. Reges made national headlines as the defense lawyer of convicted killer Larry Lord Motherwell, who died in San Quentin Prison in 1966 while serving a life sentence for the murder of Pearl Putney, a wealthy 72-year-old Washington widow.

Mr. Reges also made local headlines here while attending St. John's College High School, where he was an all-metropolitan basketball center nicknamed "Ace of Aces." He earned a basketball scholarship to Georgetown University, from which he graduated with a bachelor's degree. He earned his law degree from Columbus University School of Law, now Catholic University's law school.

He was a founding member of the National Lawyers Club here and member of the American and D.C. bar assocations.

He also was the owner of the Old Angler's Inn, an area landmark located along the C & O Canal in Potomac, which is operated by his wife Olympia.

Mr. Reges was a lieutentant and a pilot in the Army Air Force during World War II.

His first marriage to Mary Angela Cunningham ended in divorce.

Besides his wife, Olympia, of Potomac, survivors include two sons by his first marriage, John T. Jr., of Damascus, and Timothy J., of Silver Spring, and three children by his second marriage, Kathleen, Gregory and Mark, all of Potomac; three brothers, Paul and Richard, both of Washington, and Bernard, of Delaware; a sister, Sister Marie Stephen Reges of Madison, Wis., and one grandchild.
