The son of the late Washington, D.C., Mayor Marion Barry has died.

Marion Christopher Barry, 36, died Sunday, according to relatives. According to news reports, he died of an apparent drug overdose.

His girlfriend found him, and he was taken to George Washington University Hospital.

Christopher Barry, who had struggled with drug use and had recent brushes with the law, ran unsuccessfully for D.C. Council's Ward 8 seat last year after his father died. He came in sixth place on the ballot.

His father, Marion Barry, served as mayor of D.C. from 1979 to 1991 and again from 1995 to 1999. A Democrat, Barry, the best-known local political figure in D.C.'s modern history, died at the age of 78 in November 2014. He also had his struggles with drugs.

Cora Masters Barry, widow of Marion Barry, said she was not prepared to talk about Christopher Barry's death.

"It is very difficult for me right now," she told the Washington Post.

Christopher Barry had started a construction firm last year and was trying to form a community business enterprise. Trayon White, the Democratic nominee for the Ward 8 council seat, said Barry was on the site of one of his construction projects in Southeast D.C. as late as Saturday.

White, who was a protege of the elder Barry, called Christopher Barry a friend who will be missed.

"Chris was like a brother to me. He cared about the community. He had a lot of things that he wanted to work on to better the community," White said.
