Abstract

The importance of well-preserved knots and ligatures, in conjunction with clear and unambiguous photographs and other recording techniques, is demonstrated using comparatively flawed and idealized images of mock exhibits. The identification of wends (working ends), stands (standing parts), severed ends, and unobstructed crossing points is critical. Further, determining the lengths of segments and the circumferences of loops, along with rope or cord diameters, can be of assistance during an analysis. Subtle details, such as the interrelationship of various wraps and complex entanglements, can be maintained when employing careful removal procedures. Any information that might be acquired from the knotted evidence could inform subsequent determinations and conclusions. Carefully preserved exhibits and recorded details may assist the analyser of knots and ligatures in establishing the tying sequence, the purpose of those knots, the tying habits and relative skill level displayed, and possibly the number of tiers. Case-specific issues, such as whether the knotted evidence points to homicide or suicide, may be clarified.

RÉSUMÉ

L’importance des noeuds et des ligatures bien conservés, en conjonction avec des noeuds et des ligatures clairs et photographes non ambiguës et d’autres techniques d’enregistrement, est démontrée en utilisant des images relativement imparfaites et idéalisées d’expositions fictives. L’identification de extrémités, dormants, extrémités coupées et les points de passage non obstrués sont essentiels. En outre, déterminer la longueur des segments et les circonférences des boucles, ainsi que les diamètres des cordes, peuvent être utiles lors d’une analyse. Détails subtils, tels que l’interrelation de divers enveloppes et enchevêtrements complexes, peuvent être maintenus lors de l’utilisation d’un retrait soigneux Procédures. Toute information qui pourrait être obtenue à partir de la preuve nouée pourrait éclairer les déterminations et conclusions ultérieures. Expositions soigneusement conservées et les détails notés peuvent aider l’analyseur de noeuds et de ligatures à établir la séquence, le but de ces noeuds, les habitudes de nouage et le niveau de compétence relatif affiché, et possiblement le nombre de niveaux. Questions spécifiques au cas, telles que la question de savoir si les noeuds indiquent un homicide ou un suicide peuvent être clarifiées.
