The paper reports on a remarkable case of corpse disposal. A 32-year-old inmate of a prison with the permission to go out on weekends had disappeared since 1 1/4 years. His corpse poured in a concrete block was found in a metal-drum having been sunk in a disused part of a river. Although formation of adipocere and putrefaction was found, the corpse was in a relatively good status of conservation. The man had been killed by a punch of a forked crowbar on his head.
