The mysterious death of former Kremlin aide Mikhail Lesin has gotten even weirder as details have emerged showing that Lesin — or someone pretending to be him — traveled out of the U.S. after his death.

Lesin, the founder of Russia’s RT news agency, largely seen as the Kremlin’s propaganda machine, was found dead in a hotel room in Washington, D.C. on Nov. 5. Although Russian media immediately proclaimed that he had died from a heart attack, many believe foul play was involved — a theory that gained credence last week when U.S. authorities announced Lesin had died from a blow to the head.
