Fatal bear attack in Russian Federation: A case report.

Human-bear conflicts are a growing concern globally, with Russia harboring a significant population of brown bears. This case report details a fatal encounter between a male hunter and a brown bear in the greater Khabarovsk region. On October 2015, the hunter's body was discovered approximately 400 m from a deceased brown bear, indicating a deadly confrontation.

[Fatal injury to the neck while working with an angle grinder].

A fatal accident using an angle grinder is presented. During the forensic medical examination of the corpse, a soft tissue wound of the neck was found, localized in the region of its anterior and right lateral surfaces, with damage to the common carotid artery, internal jugular vein, sternocleidomastoid and sternothyroid muscles, thyroid lobe, incomplete transection of the trachea and esophagus caused by the rotating disc of an angle grinder. This observation supplements the existing ideas about injuries caused by power tools, as well as the possibility of reconstructing an event based on a comprehensive assessment of data from the scene.

[The distinc features of a blood drip stain on a surface covered with house dust].

The purpose of the investigation is to establish the characteristics of a blood drip stains on a surface covered with house dust. In most cases, objects at the crime scene are covered in some degree of dust deposits. Accordingly, in external bleeding wounds, blood drops on dusty surfaces.

[Morphology of traces of large blood drops on a snow-covered surface with different bleeding source height].

Aim is to study morphology of the traces of a large drop of blood formed on snow-covered surface when it falls from different heights. In the experiment, we studied the morphology of blood drop traces fallen from 20, 50 and 100 cm on a just settled dry snow cover in a moderately frosty environment (-8 °C) Dropping from a height of up to 20 cm, a blood drop formed a cylindrical channel in the snow cover and spread out to form a disc-shaped element. However if the bleeding source was located at a 50 and 100 cm distance, an element close to a ball, consisting of blood crystals and ice was formed in the final section of the cylindrical channel.

[Influence of negative ambient temperature on the morphology of blood droplet traces].

The aim of this study was to identify the peculiarities of blood droplets on the street in frosty weather on the surfaces of objects with a negative temperature. The effect of negative ambient temperature (-19 °C) on the morphology of blood droplet traces was experimentally established. On cold trace surfaces, the droplet footprint was smaller, relatively flat and with wave-shaped edges; there was no splashing.
