Let's review the 2015 death of Vladimir Putin's media czar the night before he was scheduled to talk with U.S. Justice Department officials about the Russian media outlet RT. 

Though Mikhail Lesin’s death was ruled an accident by Russia, 

an American FBI agent said, "Everyone thinks he was whacked."

He continued: “What I can tell you is that there isn’t a single person inside the bureau who believes this guy got drunk, fell down, and died. 

Mikhail Lesin’s battered body was discovered in his Washington DC Dupont Circle hotel room on the morning of November 5, 2015 with blunt-force injuries to the head, neck, and torso. 

After an almost year-long "comprehensive investigation," a federal prosecutor announced last October that Lesin died alone in his room due to a series of drunken falls “after days of excessive consumption of alcohol.” 

His death was ruled an "accident," and prosecutors closed the case.
