The process of decomposition is complex and varies significantly from one body to another, even when they are located close to each other. Factors such as the body’s fat content, any drugs or medications taken, the clothing worn, and even unique odors can all influence the rate and manner of decay. This variability means that two bodies may decompose under identical environmental conditions yet experience entirely different processes of breakdown.

This insight is drawn from Val McDermid's work in "Forensics: What Bugs, Burns, Prints, DNA and More Tell Us About Crime." The author emphasizes the multitude of elements that can affect decomposition, highlighting the unpredictable nature of bodily decay. Understanding these variables is crucial in forensic science, as they can provide valuable information in criminal investigations.
