Investigators searched Yevgeny Prigozhin s property in St Petersburg on June 24 this year after the Wagner chief s failed mutiny against Russia s defence ministry.
Authorities say an investigation into the plane crash that allegedly killed Wagner boss Yevgeny Prigozhin is underway, as some supporters point the finger of blame at the Russia, and others at Ukraine.
Russian outlet Readovka, closely linked with Prigozhin, reported Wagner had a long-established mechanism of action in the event of the death of Yevgeny Prigozhin or Dmitry Utkin .
