The 57-year-old millionaire was found dead the morning of Nov. 5 in his room, lying on the floor. His family told media outlets that the former aide to Russian President Vladi­mir Putin had suffered a heart attack.

But on Thursday, the D.C. Medical Examiner’s Office said Lesin died of blunt force trauma to the head and had bruises on other areas of his body. The examiner reached no conclusion about whether the man who was a trusted member of Putin’s inner circle and once ruled a media empire died because of a crime, an accident or some other means.

He was found just before 7 a.m. on Election Day, lying on the floor of the Russian Consulate on the Upper East Side.

The man was unconscious and unresponsive, with an unidentified head wound — “blunt force trauma,” in cop parlance. By the time emergency responders reached him, he was dead.

Initial reports said the nameless man had plunged to his death from the roof of the consulate. As journalists rushed to the scene, consular officials quickly changed the narrative. The anonymous man had not fallen dozens of feet from the roof of the consular building, they said, but rather had suffered a heart attack in the security office, and died.

Churkin died one day before his 65th birthday. He was known as a deeply intelligent, combative, disarming and humorous fixture at the UN Security Council.

The diplomat suffered from cardiac arrest while at the Russian Mission on East 67th Street, a law enforcement official said. He was taken to New York-Presbyterian Hospital, where he died.

Preliminary information suggests there was no foul play in Churkin's death, New York police Lt. Thomas Antonetti said. But authorities are waiting for reports from the New York City medical examiner's office before releasing the official cause of death.
