How does forensic science contribute to solving cold cases?

Forensic science plays a significant role in solving cold cases by utilizing advanced technologies and methods to analyze evidence that may have been collected years or even decades prior. The correct approach involves applying modern analytical techniques to old evidence, which can lead to the identification or confirmation of suspects that may not have been possible at the time of the original investigation. These updated methods could include DNA analysis, which has revolutionized the ability to link biological evidence to individuals with greater accuracy than was previously achievable. This means that evidence that seemed inconclusive or irrelevant can now yield new insights, potentially bringing new life to a case that had gone cold.

In contrast, approaches that dismiss old evidence or focus solely on witness testimonies limit the potential for re-examination of facts that could lead to new discoveries. Simply re-interviewing suspects without the context of improved forensic methodologies may not provide new information relevant to the case. Consequently, leveraging forensic science through the analysis of existing evidence is the most effective strategy in resolving cold cases.
