The decapitated corpse of a mining company boss has been found in the latest episode of a grizzly string of mysterious deaths among senior Russian executives since the war in Ukraine started. The body of Alexey Sinistyn, CEO of potassium and magnesium mining firm K-Potash Service, was found near Russia’s Kaliningrad exclave on Monday, Russian media reported. The deceased was “found without a head,” state-run news agency RIA Novosti cited law enforcement officials as saying, adding that the body was found under a bridge with a tow rope attached to it.
