The obituary yesterday on Oscar Ernest Murden, 35, a guard lieutenant at the D.C. correctional complex at Lorton, who accidentally drowned in the Potomac River, erroneously identified his former wife. She is Dr. Alicia Heron.

Oscar Ernest Murden, 35, a guard lieutenant at the D.C. correctional complex at Lorton and a former Metropolitan police officer, was found dead Sept. 21 in the Potomac River near the Marine Corps air station at Quantico, Va. He had fallen from his fishing boat off Charles County, Md., on Sept. 18 and the Maryland State Medical Examiner's Office listed his death as an accidental drowning.

Mr. Murden, who lived at the Lorton complex, was born in Washington and attended Roosevelt High School. At the time of his death, he was a part-time student at Northern Virginia Community College.

From 1967 to 1970, he was in the Army. He served in Vietnam and won the Bronze Star. He joined the Metropolitan Police Department when he left the service. In 1976, he transferred to the D.C. Corrections Department.

He was a former member of All Souls Unitarian Church in Washington and a volunteer with the D.C. Lighthouse for the Blind.

His marriage to the former Dr. Alicia Heron ended in divorce.

Survivors include a son, Oscar E. Jr., of Alexandria; his mother Doris Sheils of Silver Spring; his father Charles Murden of Patterson, N.J.; five sisters, Karen M. Winfield of Silver Spring, Kristle M. Edwards of Tacoma, Wash., Pamela M. Chew of Annapolis, and Meryl M. Murden and Cecelia M. Titus, both of Takoma Park, and a brother, Michael, half sister, Dominique D. Dunn, and half brother, Neils C. Dunn, all of Silver Spring.
