Name a common type of evidence that can be collected from a crime scene.

• A. Fingerprint evidence
• B. Ballistic evidence
• C. DNA evidence
• D. Witness statements

Answer: (C)

DNA evidence is considered a common and highly valuable type of evidence that can be collected from a crime scene due to its ability to provide a definitive link between a suspect and the crime. DNA, which is unique to each individual (except for identical twins), can be extracted from various biological materials, such as blood, saliva, hair, skin cells, and even bodily fluids. This makes it a powerful tool for both identifying suspects and exonerating the innocent. Furthermore, advancements in forensic science have made it possible to analyze very small samples of DNA, enhancing its utility in solving crimes. When DNA evidence is matched to an individual in a database, it can serve to establish a strong correlation that supports a case. Other types of evidence, while also important, may not provide the same level of individual specificity. For example, fingerprint evidence is unique to individuals and is crucial for identification but may not be available in every case. Ballistic evidence can link a firearm to a crime but is limited to specific crimes involving shooting. Witness statements can provide crucial context but are subject to memory biases and inaccuracies. Thus, DNA evidence stands out in its reliability and effectiveness in criminal investigations.
