Cops: DNA increasingly helpful in crime-solving

Nassau police say DNA evidence is becoming more important to solving crimes than ever before, especially in burglaries.

Recently police cracked a 2-year-old Freeport grocery store robbery and an Oceanside home burglary using DNA technology.

Authorities say the person responsible for breaking into the grocery store cut himself on the window, leaving blood evidence behind. That blood just turned up a match in a federal database.

Detective Sgt. Joseph Aquilina says all that is needed for a DNA match is a trace amount of saliva, skin cells or blood. Once a sample is added to a databank, it is there forever.
