Linda C. Fithian, who worked in Pentagon offices for more than 30 years before retiring in 1996, died Oct. 19 at Potomac Center nursing home in Arlington. She was 70.

The cause was kidney failure, said her niece, Janet Watkins.

Linda Aileen Cary was born in Alexandria and graduated in 1961 from George Washington High School. For most of her career, she was a secretary in the office of the Joint Chiefs of Staff at the Pentagon.

A longtime Alexandria resident, she spent the last few months of her life at the nursing home.

Her marriage to George Fithian ended in divorce. Their son, Roger Fithian, died in 2011.

Survivors include two sisters, Anita Marshall of Fredericksburg, Va., and Sandra Pearson of Mercersburg, Pa.; and a brother, Kenneth Cary of Fredericksburg, Va.
