In the process of “DNA fingerprinting,” of which a DNA profile is created, DNA evidence from a crime scene can be used to match to criminals already in the database. A DNA profile focuses on thirteen markers, or locations, on the genome that have high variability between people. Consequently, the likelihood of two people having the same results for those thirteen markers is very small (Matheson, 2016). In fact, the chances can be as high as 1 in 1 billion (“What is a Cold Case,” 2008). While this type of testing helps to match DNA to a profile already in the database, it cannot be used for people who previously had a clean record before committing the
