Dear Police1 Member,
The arrest of the Golden State Killer in April through the use of DNA evidence and a genealogy website has put a spotlight on how DNA technologies are changing police investigations. In this month’s Investigations eNewsletter, we take a look at the history and future of using DNA in investigations.

We also highlight a new report that provides valuable insights into portable drug testing devices, and review the latest policy updates for eyewitness identification procedures.
