Scientists develop DNA test to distinguish between identical twins in forensic breakthrough that could help to solve decades-old cold cases

Scientists may finally have cracked the code to using DNA to pinpoint a specific individual from a set of identical twins.

Since it was first introduced to the courts in the 1980s, DNA analysis has transformed the way we approach criminal investigations.

But, despite more than 30 years of advancements since, there’s still one scenario that can stand in the way of nailing down the right suspect even when DNA is present: identical twins.

Identical twins arise from the same fertilized egg, and standard DNA tests are so-far unable to pinpoint the minute differences.

That means in cases where one twin commits a crime, it sometimes ends up that both walk free, as prosecutors are unable to conclude which of the two really did it.
