Thirty-eight Russians, including two connected to President Trump and 10 prominent critics of President Vladimir Putin, have been the victims of unsolved murders or suspicious deaths since 2014, USA Today reported on Tuesday.

They include 12 who were shot, stabbed or beaten to death. Another six died in explosions. Ten more died of supposedly natural causes. One died of mysterious head injuries, one slipped in a public bath, another was hanged in his jail cell and one died while drinking coffee. Six more were reported as unknown, the USA Today reported.

Two of the victims — Oleg Erovinkin and Alex Oronov — are linked to a dossier written by former British spy Christopher Steele that alleges Trump campaign officials colluded with the Kremlin during the 2016 presidential election, the report said.

Erovinkin, 61, a Russian intelligence officer, was found dead in the back of his car in Moscow on Dec. 26 of unknown causes.

Oronov, 69, a Ukranian-born businessman, died of unexplained circumstances on March 2.

He had arranged a meeting with Trump lawyer Michael Cohen, Trump associate Felix Sater and Andrii Artemenko, a member of Ukraine’s parliament, to discuss a peace plan for Ukraine that would have given Putin control of Crimea.

Artemenko claims Oronov, a naturalized American citizen, died of the stress that came with hatching the plan.

“Unfortunately, his heart could not endure it. He died … Friend, your death will not have been in vain, nor will the deaths of tens of thousands of Ukranians and Russians, Alex Oronov, during this wild, undeclared war!” Artemenko wrote on Facebook after Oronov’s death.

Vladimir Kara-Murza, a Russian political activist who worked with Putin opponent Boris Nemstov before he was shot to death in Moscow in 2012, chalked up the deaths to Moscow silencing its critics.

“We’ve seen political opposition leaders and activists, whistle-blowers, anti-corruption campaigners and independent journalists lose their lives in one way or another,” Kara-Murza told the newspaper. “Sometimes these are suspicious suicides and plane crashes, really rare and horrible diseases. In many others, they are straight murders.”

H e believes he has been the victim of attempted poisonings in May 2015 and in February.

“Twice in the past two years I have experienced symptoms consistent with poisoning, both times in Moscow,” he told USA Today. “Both times, symptoms came on suddenly and out of nowhere.

Both times spending weeks in a coma on life support machines. Both times, doctors set my chance of survival at 5 percent, so I’m very fortunate to be here today.”

But Boris Silberman, a Russia analyst for the Foundation for the Defense of Democracies, a Washington think tank, told the newspaper the some of the deaths, especially the older diplomats, were caused by poor health.

“Knowing how diplomats live, going from one cocktail party to the next and not to the gym in between, it finally catches up to you,” Silberman said.

He also said the Russia story has created a “fever” of speculation.

“Some of it is substantial. It’s almost like there’s something nefarious behind every piece of news. Sometimes there is. … They tend to clean up their messes this way,” he said.
