#MurderCapital: 'My double life as crime reporter and crack addict'
When Ruben Castaneda moved to the US capital in 1989 to take up a job with the Washington Post the city was gripped by a crack epidemic and rampant gun violence.
He was a user himself, having picked up the habit on the West Coast. Days after arriving in Washington, he was taken to S Street Northwest by a "strawberry" - a streetwalker who traded sex for drugs.
They were in the Shaw/U Street neighbourhood, less than two miles from the White House.
In his new book 'S St Rising', Castaneda chronicles his double life as a crime reporter and crack addict.
He told the BBC how his personal story of overcoming drug abuse echoes the city's transformation from murder capital of America to gentrified boomtown.
