Rapid DNA technology can provide investigators with real-time investigative information, enhance border security and public safety, aid in prevention and detection of human trafficking, and provide identifications in mass casualty events. While Rapid DNA was designed for operation by non-technical field personnel, it is important to be implemented properly with the complementary support of trained […]

Interpreting mixture samples from a bulk pipeline is arduous since the signal is a cacophony of low-fidelity fluorescence from noise, artifact and incomplete allele signal from an unknown number of contributors. The resultant electropherograms (EPGs) are sometimes so complex as to require significant computational power to complete the interpretation. An alternate to the bulk-processing pipeline […]

For the past three years, Signature Science has been working on the IARPA PROTEOS program to demonstrate that protein sequencing can successfully be used for human forensic identification for samples where DNA was either absent or degraded, specifically touch samples. Together with the University of North Texas Health Science Center and The Ohio State University, […]

Over the past decade microbial forensics has shifted from solely biosecurity applications to include human identification (HID). Studies have shown that the human skin microbiome could potentially serve as an adjunct to traditional DNA evidence, especially when the human DNA is low quantity. Recently, a custom targeted panel for the human skin microbiome has been […]

Forensic DNA analysis is typically used to target a single organism that is only one component of a more diverse biological sample, e.g., human DNA. Forensic samples can be considered a type of environmental sample and will routinely consist of many organisms. Those non-targeted organisms may hold significant value and may be used to provide […]

Y chromosome STR haplotypes have been used in assisting forensic investigations primarily for identification and male lineage determination. The Scientific Working Group on DNA Analysis Methods (SWGDAM) Lineage Marker Committee published interpretation guidelines for Y-STR typing, which provide helpful guidance. However, these guidelines do not address the issue of kinship analysis with Y-STR haplotypes. Because […]

As the world slowly starts to return to business, new challenges are faced by restrictions in the courtrooms. Combining the nerves of regular testimony with personal protective equipment (PPE) on the stand, along with temperature checks, and new check‐in procedures, adds to the stress of everyday testimony. However, many courtrooms are opting for another choice, […]

Investigative genetic genealogy is becoming a popular topic in the forensic community for its use in solving previously “unsolvable” cold cases for law enforcement. The United States, unfortunately, has very high rates of infanticides–or the murder of a child younger than four years of age. Because these children are so young and have likely not […]
