Navigating justice for sexual assault survivors
Advances in DNA technology have improved how we investigate cases and interpret forensic evidence. In some cases, DNA can provide factually irrefutable proof; therefore, more and more criminal investigators including the criminal justice system are turning to forensic scientists and laboratories for accelerated casework – perform testing, interpret results, render conclusions, and testify in court.
April is Sexual Assault Awareness Month
While “I Ask” champions the message that asking for consent is necessary, we wanted to reinforce the fact that asking for justice is also the fundamental right of every victim or survivor.
QIAGEN’s fight against sexual violence
We are partnering with forensic scientists worldwide and empowering those tasked with investigating complicated cases and bringing closure, by streamlining sexual assault workflow.
Even with forensic DNA testing being the gold standard in sexual assault cases, casework backlogs, inconclusive results from challenging mixtures, degraded or low levels of DNA, and presence of inhibitors often impede successful completion of necessary casework. Samples often contain mixtures of body fluids from the victim and offender(s), and the accused often argues for a legitimate reason for his DNA being present on the victim (e.g., skin cells from a handshake, rather than sperm cells from sexual activity). Therefore, it is critical to identify the tissue source, as sperm cells can be separated from female cellular material or epithelial cells, improving cell mixture deconvolution. DNA evidence has the power to identify the assailant(s), but reliable identification of the sperm, efficient sample lysis and careful separation are essential.
A complete DNA profile can help accurately discriminate between different individuals, by matching profiles against potential suspects or a DNA database. However, the success of forensic DNA profiling can be ensured only by implementing an efficient workflow capable of handling the typically high volume of samples submitted, as well as following a sensitive and precise quantification of total human and male DNA, and degradation assessment of both male and total human DNA. Based on such information, forensic examiners can decide whether further sample purification is needed.
