The components of the DNA test could be defective. As our understanding of DNA transfer increased, DNA analysts and Sexual Assault Nurse Examiners began advising the collection of the suspect's underwear along with penile swabs from the suspect if a limited time period (perhaps 36 hours or less) had passed between the assault and the apprehension of the suspect.
