DNA profiling of trace evidence - Mitigating evidence in a dog biting case

A young girl was the victim of a severe dog attack. An animal, suspected of having caused the attack, was later impounded for investigation. Microclot s of blood, recovered from the dog's fur, were analyzed by STR DNA. Results showed that this blood was not related to the biting. Other forensic evide nce-hairs, fibers, and odontology-failed to connect a particular animal to the attack. The implications of these findings for the dog and its owners a re discussed as well as other forensic methods for resolving such cases.
