Abstract
The article presents an expert case of electrical injury from technical electricity in water (the corpse of a girl with signs of a thermal burn was found in the bathroom, nearby there was a telephone connected to the electrical network). A forensic histological examination of the damaged tissues was carried out. The authors studied the histological picture of the electrical mark and changes in the dermis caused by electrical current in water. It was revealed that, firstly, the morphological picture of the electrical mark in water is determined by both the electrochemical damaging effect associated with the development of electrolytic processes in tissues and thermal exposure; secondly, not only the skin and subcutaneous fat, but deeper tissues are subject to massive traumatic effects which should be taken into account when the treatment of patients with non-fatal electrical injuries.
