Russian media reported the Wagner chief could be laid to rest as early as Tuesday.
Russia’s Investigative Committee has confirmed Wagner chief Yevgeny Prigozhin was killed in a plane crash.
The fatal plane crash has raised questions about the future of Yevgeny Prigozhin’s private army.
A preliminary U.S. intelligence assessment concluded the plane was downed Wednesday by an intentional explosion.
The crash was widely seen as an assassination to avenge a mutiny that challenged President Vladimir Putin.
The crash also comes after Russian media reported that a top general linked to Prigozhin was dismissed from his position as commander of the air force.
Intelligence shared with The Washington Post shows the Russian president was warned about Yevgeny Prigozhin's plans “at least two or three days” in advance.
Yevgeny Prigozhin is seen telling his troops they will spend time in Belarus training its military before deploying to Africa.
The president's comments about the Wagner mercenary leader refer to the very real reputation Russia's Vladimir Putin has for poisoning his enemies.
Russian President Vladimir Putin met with Wagner leader Yevgeny Prigozhin days after a short-lived rebellion by the mercenary chief and his private army.
