How can decomposition stages be utilized in forensic science?

Utilizing decomposition stages in forensic science is essential for estimating the time of death, a critical factor in criminal investigations. As a body undergoes decomposition, it progresses through distinct stages—such as fresh, bloated, active decay, advanced decay, and dry remains—each with specific timelines depending on environmental factors like temperature, humidity, and the presence of insects.

Forensic entomologists often assist in this process by studying insect activity, which is closely related to the decomposition stages. By understanding the general timeline of these stages, forensic scientists can estimate how long it has been since death occurred. This information can be crucial for establishing timelines in criminal cases, helping to narrow down the time frame during which a crime may have occurred and providing potential leads in an investigation.

Other options, while related to the study of a deceased individual, do not directly link to how decomposition stages inform the time of death. For example, identifying the deceased's past, determining the cause of death, or assessing health involves different forensic methodologies and analyses beyond just observing decomposition.
