Dolores “Do-Dee” Brown, an Arlington police officer who served 32 years with the county police before retiring in 1986, died July 29 at her home in Annandale. She was 77.

The cause was complications from diabetes, her daughter, Roxanne Brown-Ankney, said.

Ms. Brown was a plainclothes officer throughout her police career, serving at different times in the juvenile section, as a school resource officer and as an arson investigator, working in tandem with the County Fire Department. She also served on the governor’s task force on child abuse.

Dolores Adrianne Brown was born in Alexandria and graduated from George Washington High School in 1954.

In the 1970s, while working as a police officer, she enrolled in a law enforcement program at American University that gave academic credit for police work, and she received a joint bachelor’s and master’s degree in justice and law enforcement.

After retiring as a police officer, she was an assistant manager at Bowl America in Alexandria and office manager in Annandale of Renewing Love Ministries, a Christian-oriented, nondenominational ministry specializing in relationships with family members and others.

Ms. Brown was a member of the Cornerstone National Evangelical Free Church in Annandale.

Survivors include a daughter from a relationship, Roxanne Brown-Ankney of Annandale; a sister; and two grandchildren.
