When was DNA testing first used by the police?


Although they discerned the double helix in 1953, DNA profiling didn’t come until a few decades later.

The inquiry, otherwise known as DNA barcoding, started in the 1980s as scientists used solitary qualities of the helix to identify individuals.

Dr Jeffrey Glassberg filed the senior patent which explored this opportunity in 1983, and British geneticist Sir Alec Jeffreys evolved a profiling process the following year.

Once established, authorities hand-me-down profiling for the first time during an inquiry following murders between 1983 and 1986.
