Bill Browder believes that President Putin is behind an "epidemic of murder" of high-level Russians.
One of Putin's most high-profile critics is the man who used to be Russia's biggest foreign investor. A string of unexplained deaths of more than a dozen top Russian business figures is believed to be connected to Putin acting as the country's "mafia boss," according to Bill Browder.
He made the comments on a radio show.
At least 15 executives with strong ties to Russia's energy industries have died in different ways in the last four years. Accidents or likely suicides are what Russian authorities call them.
Dramatic falls, drowneds, and murder-suicides are some of the reported causes of death.
He said that if someone dies in that way, it should be seen as suspicious.
It looks like an epidemic of murder when people all of the same industry die at the same time.
Don't rule out the foul play.
The deaths include the murder-suicide of Sergey Protosenya and most of his family in Catalonia. Mossos D'Esquadra said that it is still under investigation.
According to local media, the body of Putin's point man at Russia's Far East Development Corporation, Ivan Pechorin, washed up on the shore after he fell from a speeding boat.
State-controlled media reported that the chair of the board of directors at a major energy company fell out of a window in an apparent suicide. The board of the oil company was critical of the war in Ukraine.
He didn't think Maganov's death would be payback for his criticism.
The deaths were more likely due to the cost of the war.
"Because of the war, there's a lot less money, and when here's a lot less money, it becomes a lot more coveted," he said. There are people sitting in front of large assets.
Shadowy figures may have requested that the money be diverted. Killing him and asking his replacement the same question is the best way to get the cash.
"My own experience says that Vladimir Putin is the mafia boss, and I think he's going to get a cut." The head of state is also the boss of the mob.
Multiple independent investigations have suggested that Putin's vast wealth is connected to his network of oligarchs and their business holdings.
The potential source of funding has been capped by the sanctions of the West.
He said that the only money that hasn't been sanctioned is the oil and gas industry's revenue.
His attempts to expose corruption in Russia ended in his expulsion from the country.
The lawyer who was imprisoned after his expulsion died there. The act in Maginitsky's name was passed by congress.
