DNA science key for law enforcement

cold case logoIn the 1993 movie Jurassic Park, DNA was used to genetically engineer dinosaurs, which then, of course, ran amok on an island amusement park. Three years later — not in a movie but in real life — scientists used DNA to famously clone Dolly the sheep.
Closer to home, the science is being used by local law enforcement agencies to help them catch bad guys. DNA helps them identify suspects, link crime scenes where there are no suspects, rule out suspects, and determine whether a serial offender may be involved in a crime.
In 2013, Lethbridge regional police were able to check DNA on a beer can they found inside a pickup truck that had been stolen from its owner. That DNA led them to a suspect who pleaded guilty in court to one count of possession of stolen property.
