What does the term "ligature" refer to in forensic contexts?

In forensic contexts, the term "ligature" specifically refers to a medium used to bind or tie objects or individuals. This is often discussed in relation to crime scenes, particularly in cases involving strangulation or suffocation, where ligatures can be crucial pieces of evidence. Such materials can include ropes, cords, or other items that may have been used to restrain a person or alter their ability to breathe.

Identifying and analyzing ligatures at a crime scene can provide valuable information regarding the circumstances of an offense, including the manner in which an act was committed and potentially the identity of the perpetrator through trace evidence. The forensic examination of ligatures can also reveal details about the materials used, which can be linked back to specific locations or items found in a suspect's possession.

Understanding the role of ligatures in criminal investigations enhances an evidence technician's ability to collect and preserve important evidence, contributing to the overall investigation and prosecution of a crime.
