As DNA technology advances, solving cold cases is becoming increasingly easier, with offenders more likely to be caught from just one piece of DNA evidence left at the scene. This could potentially deter others from committing violent crimes in the future.
In cases where there is not enough DNA data to draw conclusions or the case does not fit the laboratory's criteria, the case is put into a backlog of cases until there are enough similar cases with positive outcomes to attempt analysis; despite this, investigators use available records to make matches for missing people.
The continuous development and usage of DNA evidence at scale and work towards solving past cold cases will become increasingly effective in deterring violent crimes and making society safer. This could lead to fewer unidentified cases in the future.
