The Russian effort to exploit Rich’s tragic death didn’t stop with the fake SVR bulletin. Over the course of the next two and a half years, the Russian government-owned media organizations RT and Sputnik repeatedly played up stories that baselessly alleged that Rich, a relatively junior-level staffer, was the source of Democratic Party emails that had been leaked to WikiLeaks. It was an idea first floated by WikiLeaks founder Julian Assange, who on Aug. 9, 2016, announced a $20,000 reward for information about Rich’s murder, saying — somewhat cryptically — that “our sources take risks.”

At the same time, online trolls working in St. Petersburg, Russia, for the Internet Research Agency (IRA) — the same shadowy outfit that conducted the Russian social media operation during the 2016 election — aggressively boosted the conspiracy theories. IRA-created fake accounts, masquerading as those of American citizens or political groups, tweeted and retweeted more than 2,000 times about Rich, helping to keep the bogus claims about his death in the social media bloodstream, according to an analysis of a database of Russia troll accounts by Yahoo News.

Speaking publicly about the case for the first time, Sines, the former prosecutor, said that the Russian conspiracy-mongering vastly complicated her efforts to solve the murder by forcing her and the Washington, D.C., police department to investigate a blizzard of false allegations in order to make sure there was nothing to any of them. “To waste your time investigating BS is just horrible,” said Sines.
