What is the correct order of evidence collection at a crime scene?

The correct order of evidence collection at a crime scene emphasizes the importance of prioritizing evidence based on its transience and practicality of collection. The approach involves first identifying and prioritizing the evidence present, allowing investigators to focus on the most transient evidence, which is susceptible to change or loss over time. Collecting the most transient information first ensures that critical evidence is preserved, as this type can vanish or degrade if not addressed promptly.

Focusing on the easiest evidence to collect first takes into consideration the efficiency of the process, allowing investigators to efficiently manage time and resources while ensuring that valuable evidence is not overlooked. This methodical approach is crucial in maintaining the integrity of the crime scene and ensuring that all important evidence is documented and collected properly.

The other options do not follow this structured and prioritized approach. Collecting all evidence simultaneously could risk contaminating the scene and missing crucial information, while investigating before collecting may lead to the destruction or alteration of key evidence. Collecting from least to most transient would not prioritize the most critical evidence and thereby could compromise the investigation.
