DNA samples collected from individuals under arrest using the FBI Convicted Offender DNA Collection Kit are collected using?

• A. Blood samples
• B. Buccal cells obtained from the insides of the cheeks
• C. Saliva
• D. Hair follicle cells

Answer: (B)

The key idea is that this kit uses a non-invasive cheek swab to collect DNA, specifically buccal cells from inside the cheek. Buccal swabs are quick, comfortable for the person, and provide ample, high-quality DNA for CODIS analysis when collected under a standardized protocol. This approach also minimizes risk and handling complexity for officers in the field or processing room, while ensuring consistent sample quality and a clear chain of custody. Blood collection would be more invasive and time-consuming, making it less practical for rapid offender processing. While saliva can be used for DNA in other contexts, the FBI Convicted Offender DNA Collection Kit standardizes on cheek swabs. Hair follicle samples can yield DNA but are less reliable and require follicles from the hair, making this method less consistent for routine offender collections.
