What could be a consequence of improper biological evidence handling?

• A. Increased clarity in the investigation
• B. Contamination that could ruin evidence in court
• C. No real impact on the investigation's validity
• D. A boost in case closure rates

Answer: (B)

Improper handling of biological evidence can lead to contamination, which is a significant concern in forensic investigations. When biological samples, such as blood, saliva, or other bodily fluids, are not handled correctly—whether through improper storage, lack of sterilization, or inadequate chain of custody—the integrity of the evidence can be compromised. Contamination can introduce foreign DNA or other biological materials that could lead to false conclusions during analysis. For instance, if a sample is inadvertently mixed with another or exposed to an environment where cross-contamination can occur, it may no longer accurately represent the original source. As a result, this tainted evidence can be deemed inadmissible in court, making it difficult or impossible to prosecute a case successfully. The reliability of forensic evidence is paramount, as it often plays a crucial role in establishing guilt or innocence. Therefore, proper evidence handling is essential to maintain the purity of biological samples, ensuring that they can be confidently presented and upheld in a legal setting.
