What is the function of a 'control sample' in forensic analysis?

The function of a 'control sample' in forensic analysis is primarily to provide a baseline for comparison with suspect samples. Control samples are collected from known sources and help analysts determine whether the evidence obtained at a crime scene can be linked to a suspect, victim, or location. By comparing the characteristics of the control sample with those of the suspect sample, forensic experts can draw conclusions about the relevance and significance of the evidence.

These comparisons are crucial in establishing connections and can assist in verifying hypotheses about how a crime may have occurred. The integrity of the forensic analysis relies significantly on the use of control samples, which help ensure that the evidence is analyzed systematically and accurately.
