Prigozhin was thought to have died in a 2019 plane crash, only to reappear days later. This time, there's more evidence he's dead.

• Wagner Group boss Yevgeny Prigozhin is presumed dead after a plane crash outside of Moscow.
• He was incorrectly reported as having possibly died in a plane crash in 2019.

Wagner Group boss Yevgeny Prigozhin is presumed dead after a plane crash on Wednesday.

But this isn't the first time the warlord, who had attempted an uprising against Putin, is thought to have died in a plane crash.

Russian news outlet Readovka reported in October 2019 that Prigozhin had died after his plane crashed in the Democratic Republic of the Congo, citing sources related to his Wagner mercenary group.

But Russian news agency RIA Novosti then reported two days later that he wasn't dead, but had just been busy and was surprised by the reporting. The agency noted that some media outlets and bloggers had reported the news.

The case has strange parallels to news this week of Prigozhin's possible demise after a private jet that he was listed as a passenger crashed in Russia's Tver region outside of Moscow.

His apparent death comes two months after he started an uprising that involved his forces taking a key Russian military base. Wagner soldiers started to march towards Moscow before striking a peace deal with the Kremlin.

However, there seems to be some more evidence this week compared to in 2019: Moscow's civil aviation agency said Prigozhin was on board, a Telegram channel associated with the group announced his death, and his body was reportedly identified in a morgue.

But some are still skeptical that Prigozhin is definitely dead, and are waiting for more evidence.

Keir Giles, Russia analyst at London-based Chatham House told The Washington Post that "until we know for certain it's the right Prigozhin, let's not be surprised if he pops up shortly in a new video from Africa," referring to the continent where the Wagner Group is also active.

Prigozhin is also a well-known purveyor of misinformation. He financed a "troll factory" that's accused of interfering with US elections.

Experts told Insider that there are three likely scenarios for what happened this week: he is dead because Russian President Vladimir Putin ordered it, he is dead because someone else ordered it, or that Prigozhin didn't actually die and faked his death.

Many are pointing to Putin being responsible, noting that the Russian president has been linked to the killings of many critics and enemies.

White House National Security Spokesperson Adrienne Watson said that if Prigozhin's death is confirmed "no one should be surprised."

UK defense sources told the BBC that Russia's FSB security and spy agency, which Putin once led, is the party most likely to have targeted the plane.
