Nine Russians -- all in key positions -- have wound up dead in recent months

At least one appears to be an assassination

Washington CNN  — 

Nine high-profile Russians, including several high-profile diplomats, have died over the nine months since the US presidential election on November 8.

Among the recent deaths were six Russian diplomats. Some of the deaths appeared natural and governments have ruled out foul play.

In some cases, though, questions remain. That’s either because the facts have changed over time, details are hard to come by, or the deaths are still under investigation.

Self-proclaimed online sleuths and conspiracy theorists have filled the information void with speculation that the deaths were somehow related to Russia’s interference in the 2016 presidential election. No evidence has surfaced to make such a connection.

Here’s a rundown of the nine deaths – and one near-fatality:

Russian politician who fled to Ukaine shot dead

Denis Voronenkov, 45, was gunned down Thursday outside a hotel in Kiev. Voronenkov and his wife both spoke out against Russian President Vladimir Putin after they left Russia for Ukraine in October.

Voronenkov also helped Ukraine in its ongoing fight against Russian influence, testifying in a treason trial against ex-Ukrainian President Viktor Yanukovych, who was perceived as a puppet politician for Putin.

Ukraine’s president called the shooting a “Russian state terrorist act.” Russian authorities denied the accusation.
