What type of cases can DNA analysis be particularly useful for resolving?

DNA analysis plays a crucial role in resolving cold or unsolved cases due to its ability to provide definitive evidence that can link a suspect to a crime scene or victim. In law enforcement, cold cases often involve crimes such as homicides or sexual assaults where biological evidence, such as blood, saliva, or hair, may still be preserved. Advances in DNA technology allow forensic scientists to analyze these samples even years after the crime occurred, sometimes leading to breakthroughs in investigations that have long gone cold.

Unlike the other options mentioned, cold cases typically involve physical evidence that can be directly connected to individuals through DNA profiling. Speeding violations, school attendance issues, and financial fraud investigations do not typically benefit from DNA analysis, as they do not involve physical or biological evidence that can establish a direct link between individuals and a particular incident.
