How can forensic investigators determine which of identical DNA Twins committed a crime?

What method can be used to distinguish between identical twins?
Using what’s known as ultra-deep, next-generation sequencing, a team in Germany has developed a test that claims to reliably identify which twin a biological sample belongs to. The test works by taking a close look at the genetic letters (called base pairs) comprising the 3 billion-base-pair human genome.

Do identical twins have the same blood DNA?
It is a basic tenet of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and, thus, share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not.
Do identical twins come from Mom or Dad?
So, having identical twins is not due to genetics. On the other hand, fraternal twins can run in families. In fact, a woman that has a sibling that is a fraternal twin is 2.5 times more likely to have twins than average!
Why are identical twins not exactly?
DNA Differences Identical twins do indeed start with identical DNA—they are the result of the same sperm from dad and the same egg from mom. The original fertilized egg divides one or more times before the resulting clump of cells splits into two. Each clump of cells goes on to become one of the identical twins.
