Karl L. Gochenour, 68, a former champion duckpin bowler who managed and operated local bowling alleys for 40 years before retiring in 1971, died Friday at his Washington home after a heart attack.

In the 1930s and early 1940s, Mr. Gochenour ranked among the top 10 bowlers in the country and was among the top five bowlers in the Washington area.

He managed and was part owner of the Brookland Bowling Alley in Washington in the 1940s and 1950s and then owned the Fort Davis Bowling Alley here until about 1970, when he became manager of the Pla-Mor Bowling Alley in Arlington.

Mr. Gochenour was an active member of the Eastgate, Riverdale and Silver Hill Lions Clubs during the past 36 years.

He was born in Crimora, Va., and moved to Washington as a boy.

Survivors include his wife, Irene, of Washington; two daughters, Karlene L., of Deptford, N.J., and Nancy G. Stiltner of Springfield; three brothers, Roy M., of Monroe, La., Herman E., of St. Petersburg, Fla., and Olin C., of Conway, S.C.; and two sisters, Alma Lewis of Oxford, Miss., and Mae Adcock of Baltimore.

The family suggests that expressions of sympathy be in the form of contributions to the Lions District 22-C, Eye Bank and Research Foundation Inc., Washington.
