What is the main purpose of maintaining chain of custody?

• A. To document who controlled a piece of evidence from discovery to court
• B. To determine the credibility of witnesses
• C. To prove guilt beyond a doubt
• D. To determine the admissibility of testimony

Answer: (A)

The main idea is that the chain of custody provides an unbroken record of everyone who has handled a piece of evidence from the moment it is collected until it is presented in court. This documentation shows who had custody, when transfers occurred, and how the item was stored, helping prove that the evidence remains the same item and has not been tampered with. By keeping this trail, the evidence’s authenticity and integrity are protected, which supports its admissibility and the weight it is given in a case. This focus on documenting control and handling is what makes it the best answer. Determining credibility of witnesses is about their testimony, not the physical evidence. Proving guilt beyond a doubt is the overall burden of the case, not a function of tracing custody. And admissibility of testimony concerns what witnesses may say in court, rather than how physical evidence has been maintained.
