DDC Forensic Services provides comprehensive services in cases involving DNA evidence, from crime scene to courtroom. Our DNA forensic testing services help identify possible sources of DNA evidence, create DNA profiles from these sources, and compare the profiles of suspect, victim, and evidence. Our forensic scientists can deliver expert testimonies and provide case consultation and review of the DNA evidence presented in a case upon request.
Finding DNA Evidence
From identifying perpetrators through a "cold hit" on the national convicted offender database, CODIS (Combined DNA Index System), to exonerating wrongfully convicted individuals, DNA testing has increasingly become an indispensable tool to help ensure justice.
DDC has a number of presumptive and confirmatory tests that detect the presence of blood, semen, and other biological materials left behind at a crime scene. When sources of human DNA are found, our laboratory scientists will extract the DNA for testing and analysis. Depending on the sample type (blood, hair, bone, vaginal swab, etc.) and condition, one or more of the following testing systems may be used:
DDC offers complimentary training on collecting crime scene evidence for DNA analysis. We conduct trainings at our mock crime scene facility in Fairfield, Ohio. Please contact us for more information.
Linking DNA Evidence
When DNA evidence has been analyzed, the DNA profile can be used to link the evidence to a suspect, or to link different crimes together, such as when DNA from a single perpetrator is found at two different crime scenes.
DNA evidence can also be used to prove the innocence of a falsely accused or wrongly convicted person, as well as identify the bodies of victims of violent crimes, accidents, or natural disasters. The power of DNA technology in identifying individuals and establishing biological relationships makes its applications limitless.
