Russia's aviation agency had previously published the names of all 10 on board the private jet which crashed in the Tver region northwest of Moscow on Wednesday. They included Prigozhin and Dmitry Utkin, his right-hand man who helped found the Wagner group. 

“As part of the investigation of the plane crash in the Tver region, molecular-genetic examinations have been completed,” Russia’s Investigative Committee said in a statement on the Telegram messaging app. 

“According to their results, the identities of all 10 dead were established. They correspond to the list stated in the flight sheet,” it said. 

Authorities have yet to say what they believe caused his private jet to fall from the sky.
