Forensic Science
DNA barcoding is often used for species identification in forensic science cases. Unknown animal or plant samples at crime scenes can be found, collected, and identified, in hopes of linking it to a suspect and getting a conviction. Poaching, killing of endangered species, and animal abuse are examples of crimes where DNA barcoding is used, since animal DNA is often found. Once identified, plant DNA is usually used as trace evidence to link a suspect to a crime scene.
