Autopsy: Former Putin aide died of blunt force trauma in DC

WASHINGTON (AP) -- An autopsy has found that blunt force trauma to the head was the cause of death for a former aide to Russian President Vladimir Putin whose body was found in a Washington hotel room.

District of Columbia police spokesman Officer Hugh Carew confirmed the autopsy results for Mikhail Lesin on Thursday. Carew says the D.C. Medical Examiner's Office found the manner of death to be undetermined. Carew says police continue to investigate Lesin's death, as they have since his body was found at the Doyle Dupont Circle Hotel in November.

After his death, Russian media reported that he had suffered a heart attack, citing his family members.

Lesin was a media adviser to Putin who helped found the English-language news service Russia Today.
