"The Russian Embassy to the United States has repeatedly sent through diplomatic channels inquiries about the progress of investigation into the death of Russia's citizen. The US side has not provided to us any substantive information," Russian Foreign Ministry spokeswoman Maria Zakharova wrote today on her Facebook page on Friday.
"We are awaiting the related clarifications from Washington and the official data on the progress of the investigation. If the information published by the media today is confirmed, then Russia's competent authorities will send a request to the US side for international legal assistance," she wrote.
Lesin died on November 6, 2016 at the Dupont Circle in the center of the US capital at the age of 57. The police found nothing suspicious at the scene then.

Lesin held the post of Russia's Minister for the Press, TV and Radio Broadcasting and Mass Communications between July 1999 and February 2004. In 2013-2014 he was the CEO and Chairman of the Board of Gazprom-Media Holding, TASS reports.
