A sledgehammer was also used to kill convicted murderer Yevgeny Nuzhin, 55, in November.
Nuzhin, who enlisted in the Wagner Group during the invasion, was said to be executed for claims of treason.
In recent months, the mercenary group are thought to have taken massive casualties. Out of 50,000 people conscripted to the group from Russian jails, 40,000 are believed to be dead, missing, or have deserted their posts.
Anybody who is captured for desertion by the group is likely to suffer a similar fate to Nuzhin. But it’s not just hammering the group used to punish their men. They also reportedly cut off fingers or castrate and skin their men alive.
