There's a black box of Prigozhi plane, they start investigating.

Russian investigators have found the black box flight recorder from Wagner's chief Yevgeny Pigozin's plane, which allegedly crashed in Moscow.

The investigative committee also said that troops found at the crash site would submit to the genetic test to confirm their identity, writes the “TheTelegraph”.

“The edition will carefully control all possible versions of what happened”, the committee said through a telegram.

Although both recorders and troops have been recovered, it may be long before official investigation data is released.

Black boxes contain large quantities of flight data to analyze, as well as cabin audio recordings.

Russian authorities have cited the need to wait for the results of the DNA test to confirm Prigozhin's death, but Vladimir Putin has already expressed his condolences.

The Kremlin, meanwhile, has denied involvement in the plane crash case.
