The forensic literature on the pathophysiology of human hanging is still limited. Therefore, forensic pathologists often feel uncomfortable when confronted with related questions. Here presented is the filmed suicidal hanging of a 37‐year‐old man. This recording allows a unique analysis of agonal movement sequences: loss of consciousness (13 sec), convulsions (15 sec), decortication rigidity (21 sec), decerebration rigidity (46 sec), second decortication rigidity (1 min 11 sec), loss of muscle… 
Agonal Sequences in Four Filmed Hangings: Analysis of Respiratory and Movement Responses to Asphyxia by Hanging *
TLDR
Despite differences in the types of hanging, this unique study reveals similarities that are further discussed that may hold the key to answer questions regarding the sequence of events leading to death in human asphyxia.
Agonal Sequences in Eight Filmed Hangings: Analysis of Respiratory and Movement Responses to Asphyxia by Hanging *
TLDR
This study analyzed eight filmed hangings and found that rapid loss of consciousness was observed, closely followed by convulsions, and a complex pattern of decerebrate rigidity and decorticate rigidity then followed.
Six‐Year Retrospective Study of Suicidal Hangings: Determination of the Pattern of Limb Lesions Induced by Body Responses to Asphyxia by Hanging *
TLDR
The proportion of hanging victims presenting with limb lesions was estimated, to compare this rate between hanging in restraint spaces and in more open settings, and to describe the usual pattern of limb lesions associated with hanging.
An overview of the mechanical asphyxia with the main emphasis on hanging
TLDR
In this review, selected studies recently reported on suicidal hangings are selected according to the criteria used to determine the method of death in the autopsy records of the Department of the Forensic Medicine and Criminalistics at the Medical Faculty in Rijeka (from 1966 to the beginning of 2017).
Injury after non-judicial hanging
TLDR
The overall incidence of cervical spine injury after hanging is low and spinal immobilisation should probably be instituted depending on the mechanism of the hanging; however, a patient presenting with signs of life to an emergency department is unlikely to have a severe cervical spine injuries.
Mechanism of Death in Hanging: A Historical Review of the Evolution of Pathophysiological Hypotheses
TLDR
The historic experiments that shaped current theories about the pathophysiology of death by hanging were reviewed, including respiratory asphyxia, interruption to cerebral blood flow because of occlusion of vessels in the neck, and cardiac inhibition secondary to nerve stimulation.
Further Observations on the Speed of Death in Hanging
TLDR
The speed with which death may result from hanging not only gives an insight into fatal pathophysiological mechanisms, but also provides useful information for situations where a lethal outcome is to be avoided, or is not intended.
Death by hanging: a retrospective case-control investigation of the intervertebral disc vacuum phenomenon on PMCT
TLDR
The presence of centrally located VP can indicate that hanging could be considered as an alternative mechanism of death and that great forces and loads may have affected the spine perimortem, especially with decreasing age and when Simon’s bleedings are present.

The course of respiration and circulation in death due to typical hanging
TLDR
The analysis of the ECG complexes revealed that the heart muscle adapted to oxygendeficiency during typical hanging, and was almost the same as that in obstructive asphyxia.
