James McConnell Truitt, 60, a former executive and reporter with The Washington Post, Newsweek and Time Inc., committed suicide Tuesday at San Miguel de Allende, Mexico.

"Jim Truitt was a brilliant, sensitive man," Katharine Graham, the chairman of The Washington Post Company, said yesterday. "He had a special appreciation for what was new and interesting and good in art and literature."

Mr. Truitt, who had lived in San Miguel de Allende since 1969, joined Time Inc. in 1948. He was assigned to the Time-Life bureau in Washington for several years and later to New York, where he was chief of correspondents for Life Magazine. Other assignments included Dallas, where he was chief of the Life bureau, and San Francisco, where he was bureau chief for all Time publications.

In 1960, he returned to Washington and went to work for The Post as assistant to the late Philip L. Graham, then the publisher of the newspaper. He was appointed a vice president of the company and the publisher of Art News, which at that time was owned by The Washington Post Company.

In 1964, Mr. Truitt joined Newsweek, another publication of The Washington Post Company, and was the magazine's bureau chief in Tokyo for three years. He returned here for Newsweek and in the late 1960s was one of the first editors of The Post's Style section. He resigned in 1969.

Mr. Truitt, who was born in Chicago and reared in Baltimore, graduated from the University of Virginia. He served in the Navy in the Pacific during World War II. He worked for the State Department here before joining Time Inc.

His marriage to Anne Dean Truitt ended in divorce.

Survivors include his wife, Patt, of San Miguel de Allende; three children by his first marriage, Alexandra Kusack and Mary Finch, both of New York City, and Samuel R., of Washington, and three grandsons.
