Why is it important to collect the most fragile evidence first when processing a vehicle?

Collecting the most fragile evidence first when processing a vehicle is crucial because such evidence is often at a higher risk of being compromised or destroyed during the collection of other, more substantial evidence. Fragile evidence, such as hair, fibers, or certain types of trace evidence, can be easily disturbed or lost due to movement, environmental conditions, or the very act of collecting more robust evidence. If fragile evidence is not prioritized, there is a substantial chance it could be altered or inadvertently destroyed before it can be documented or collected effectively. Therefore, addressing this delicate evidence first helps ensure that it is preserved for thorough examination and analysis later on. This practice enhances the overall integrity of the investigation and can significantly influence the outcomes of forensic examinations.
