Once a Sheriff’s Deputy in Florida, Now a Source of Disinformation From Russia

In 2016, Russia used an army of trolls to interfere in the U.S. presidential election. This year, an American given asylum in Moscow may be accomplishing much the same thing all by himself.

A dozen years ago, John Mark Dougan, a former deputy sheriff in Palm Beach County, Fla., sent voters an email posing as a county commissioner, urging them to oppose the re-election of the county’s sheriff.

He later masqueraded online as a Russian tech worker with a pseudonym, BadVolf, to leak confidential information in violation of state law, fooling officials in Florida who thought they were dealing with a foreigner.

He also posed as a fictional New York City heiress he called Jessica, tricking an adviser to the Palm Beach County Sheriff’s Office into divulging improper conduct by the department.

“And boy, did he ever spill ALL of the beans,” Mr. Dougan said in a written response to questions for this article, in which he confirmed his role in these episodes.

Those subterfuges in the United States, it turned out, were only a prelude to a more prominent and potentially more ominous campaign of deception he has been conducting from Russia.

Mr. Dougan, 51, who received political asylum in Moscow, is now a key player in Russia’s disinformation operations against the West. Back in 2016, when the Kremlin interfered in the American presidential election, an army of computer trolls toiled for hours in an office building in St. Petersburg to try to fool Americans online.
