The Nassau police department is on the hunt for about 1,200 convicted criminals -- required by state law to provide a DNA sample -- a unique endeavor that has netted the force scores of arrests, police said.
While departments across the state take DNA from convicted criminals at the time of their next arrest, Nassau is one of the few that go out and search for those who owe DNA regardless of when the crime was committed, officials said.
In the past three years, Nassau police have collected 572 samples from those convicted of all felonies and penal code misdemeanors -- including felony DWI. Police don't track how many crimes are solved as the result of DNA collection but estimate about one of every 50 samples collected leads to an arrest.
