She will give the DNA fingerprinting report to the jury which will have samples of suspect and its profile matching to the evidence found at the scene of crime.
In DNA fingerprinting hair, blood, semen, or other biological samples are required for the comparison of suspect and evidence. It depends on the unique polymorphism in their DNA.
