Let’s assume that a lab has come back with a report that a person’s DNA was found at a crime scene, and let’s assume that the technician at the lab hasn’t committed some kind of fraud. For instance, let’s assume that the technician hasn’t falsified the results.

DNA forensic analysis has come a long way since it was first developed in the early 1980s and commercially available in the late 1980s. Improvements in collection, quantification, and amplification techniques have meant that forensic technicians – the men and women employed by places like the State Bureau of Investigation – are now able to develop DNA profiles from relatively small amounts of biological evidence collected from a crime scene.
