What is a primary reason for conducting a search for fingerprints last in the investigation?

Conducting a search for fingerprints last in the investigation is primarily focused on the need to avoid contaminating other types of evidence that may be present at the crime scene. Fingerprints are often fragile and can be easily disrupted or compromised by moving objects, applying dust or chemicals, or touching surfaces where they might be located. By leaving the fingerprint analysis till the end of the investigation, analysts ensure that other evidence types, such as biological materials, trace evidence, or physical evidence, remain uncontaminated and intact for proper collection and analysis.

In contrast, while fingerprints can certainly be valuable, they require careful handling and processing, making it crucial to prioritize other evidence that might be more susceptible to degradation or contamination during the investigation process.
