Taking a DNA sample is relatively easy. It can be done by swabbing the inside of a persons mouth or taking a blood sample. It’s something done to every person convicted of a felony. Their DNA profile is then sent to the state crime lab, where it is kept in a database database with other convicted offenders. Then, evidence collected at a crime scene is run through the DNA database to see if there’s match.
