Which statement is true about mishandling crime scene evidence?

• A. Evidence may be contaminated
• B. Evidence may be conclusive
• C. Evidence becomes stronger
• D. Evidence becomes inadmissible automatically

Answer: (A)

Mishandling crime scene evidence threatens its reliability from collection through presentation. When evidence isn’t properly protected, it can become contaminated—substances, fibers, or even fingerprints from unrelated sources can be transferred onto the evidence, or the evidence can be degraded by improper storage, temperature, or exposure. Contamination can obscure or alter what actually happened, making analysis less trustworthy and interpretation more uncertain. That’s why the statement that mishandling may contaminate evidence is true. It’s not accurate to say the evidence may be conclusive if mishandled, because contamination or improper handling undermines reliability and weakens the ability to prove facts. Likewise, evidence does not become stronger as a result of mishandling. Regarding admissibility, mishandling can raise red flags and lead to challenges to authenticity or chain of custody, but it does not automatically render evidence inadmissible in every case; the court weighs the issues and may still admit or exclude based on the surrounding circumstances.
