Just one week after a former Russian living in Britain was hospitalized in serious condition after being mysteriously poisoned, there are reports that a Russian exile has been found dead in his London home.

Nikolai Glushkov, 68, was discovered late Monday night. The cause of death is not yet known.

In the 1990s, Glushkov was a former executive of Russia’s largest airline, as well as a former finance manager of a Russian automobile manufacturer. He was charged with money laundering and fraud in 1999, spent five years in jail, and was freed in 2004. He has lived in London after receiving political asylum.

His death joins a string of suspicious Russian-linked deaths and incidents in England.

Glushkov’s friend and Putin critic Boris Berezovsky was found dead in March 2013 in a Berkshire home. At that time, Glushkov told the Guardian that he was “definite Boris was killed” because he had “quite different information from what is being published in the media.”

Glushkov continued, “too many deaths [of Russian exiles] have been happening.” And now he is one of them.

RedState first covered Skripal’s poisoning on Sunday. Yesterday, RedState front-page contributor Sarah Lee provided an update, as British Prime Minister Theresa May told Parliament it was “highly likely” Russia was involved in the poisoning. May gave Russia until the end of today to respond, stating that otherwise the U.K. would view the poisoning as “an unlawful use of force by the Russian state against the United Kingdom.”

Scotland Yard has issued a statement that “there is no evidence to suggest a link to the incident in Salisbury.”

The White House reaction to Skripal’s poisoning was “as soon as we get the facts straight, if we agree with them, we will condemn Russia or whoever it may be,” but it has not yet commented on this most recent death.
