Message from the Forensic Science Standards Board (FSSB)
The positive progress during the first full year of OSAC has not been without some operational and communications challenges. While OSAC processes were developed to be transparent and thorough, we realized over the past year that further efficiencies and improvements could be gained.
With this focus in mind, the FSSB conceptualized and attended the recent OSAC Leadership Strategy Session on June 22, 2016. Three representatives from each OSAC main committee contributed, providing both written and verbal feedback related to the OSAC program. This exercise ultimately resulted in 25 programmatic recommendations that are now under further consideration and analysis for potential implementation later this year. Recommendations included:
• Refining OSAC infrastructure and processes to be more efficient without sacrificing quality. This will help ensure that OSAC members' time is used wisely, and will maximize their strategic input to scientifically sound standards and guidelines.
• Potentially refining the infrastructure to foster additional inter-committee efforts, so that collaboration between human factors, quality, legal, and statistician stakeholders can occur with forensic science practitioners as early and as often as practical.
• Developing an overarching strategy to best achieve timeliness, relevance, consensus, and quality in OSAC standards.
OSAC Leadership Strategy Session. John Paul Jones, Associate Director of OSAC Affairs at NIST, facilitated the OSAC Leadership Strategy Session. Attendees discussed a path forward for OSAC that will maximize collaboration between the various stakeholders.
One recommendation was to continue to hold these leadership discussions regularly, in order to ensure that these inter-committee and inter-stakeholder discussions continue at the committee chair level and beyond.

OSAC Digital Evidence Subcommittee Survey on Accreditation, Standards and Certification
As the digital evidence forensic discipline progresses, there are questions regarding quality assurance policy that need to be addressed. The Scientific Working Group on Digital Evidence and the OSAC Digital Evidence Subcommittee created a survey to seek stakeholder opinions regarding laboratory accreditation, digital evidence standards, and examiner certification. Please take a few minutes and complete the survey; it will close on December 1st, 2016. Your participation is valued and will help those writing policy guides and standards from the perspective of the entire community.
Upcoming Public Comment Period for Standards/Guidelines Under Consideration for the OSAC Registry
The Chemistry/Instrumental Analysis SAC has submitted the following standard (ASTM: E2451-13 Standard Practice for Preserving Ignitable Liquids and Ignitable Liquid Residue Extracts from Fire Debris Samples) to the OSAC Registry.

On the Horizon
(OSAC Meetings for OSAC Members and Invited Guests) The next full OSAC meetings are scheduled for summer 2016 in Phoenix, AZ. Instead of meeting as one large group, the OSAC will meet separately in a series of smaller meetings.
o (OSAC Meeting Breakout #4) Biology/DNA SAC + 3 Subcommittees, and Crime Scene SAC + 7 Subcommittees, Aug 23-26, 2016
o (OSAC Meeting for OSAC Members and Invited Guests) The following full OSAC meeting is scheduled for April 3-7, 2017, tentatively in Leesburg, VA.
o OSAC public meeting date and times will be announced shortly.
Biology/DNA SAC News- The Biology/DNA Scientific Area Committee approved the Wildlife Forensics General Standard document in July 2016 and the document was submitted to the American Academy for Forensic Sciences (AAFS) Academy Standards Board (ASB) for consideration. The document will now move through the ASB process where it will hopefully be converted into an SDO approved standard which can then be considered by the OSAC for inclusion on the Registry of Standards. Kathy Moore, Chair of the Wildlife Forensics Subcommittee gave a presentation at the Green Mountain conference the last week of July. The Biology/DNA SAC, the Biological Methods Subcommittee, the Biological Data Interpretation & Reporting Subcommittee, and the Wildlife Forensics Subcommittee will be meeting August 23-26 in Phoenix, Arizona to continue work on several documents, including a terminology document for forensic biology, validation of probabilistic genotyping systems, internal validation of existing mixture interpretation procedures, and training/education requirements for serologists and DNA analysts. Dr. George Herrin, Chair of the Biology/DNA SAC is scheduled to give a presentation at the 27th ISHI meeting in Minneapolis, MN on September 29, 2016 covering recent SAC activities.

OSAC Featured Unit: Wildlife Subcommittee
By Kathy Moore, M.S., Chair of OSAC Wildlife Subcommittee
Wildlife forensics differs from human forensics in a variety of notable ways. In human forensics, the focus is on identifying the perpetrator of a crime. In wildlife forensics, the first step is often determining whether or not a crime has occurred, which depends on whether a protected animal or plant species is involved—and there are many, many species to consider. Identifying the species (such as black bear) is often what is required—rather than identifying the individual (Smokey Bear). Species-level identifications are based on class characteristics, diagnostic for particular species. These may be either physical, morphological characteristics or genetic sequences. Due to the great diversity of species that must be considered in wildlife forensics investigations, the development of databases used for individualization and geographic assignment is prioritized by different laboratory programs. In contrast to human DNA analyses, there are no standardized commercial kits to be used in DNA analysis of wildlife species, and loci are not standardized among laboratories that analyze the same species. Wildlife forensic laboratories also tend to be small, where an analyst is responsible for everything from sample login, through analysis, to generation of the report. Crimes investigated by wildlife forensic scientists include:
• Poaching (killing wild animals in violation of the law)
• Trafficking in protected animals/plants or products
• Seafood fraud
• Animal cruelty
• Animal attacks
• Human crimes if animal evidence is probative
In 2012, SWGWILD compiled several published sources to estimate that the transnational illicit wildlife trade, including wildlife, timber, and illegal fishing, is worth approximately $53 billion a year. A 2013 Scientific American article indicated that "illegal wildlife trafficking is an estimated $19-billion-a-year industry, which makes it the fourth most lucrative illicit activity in the world after the drug trade, counterfeiting and human trafficking." Wildlife forensic scientists are few in number, but analyze evidence related to this large and complex international trade, as well as suspected violations of domestic game and animal protection laws.
Examples of evidence items that could come across the lab bench of a wildlife forensic analyst include: thousands of pounds of suspected mislabeled fish, a feather cape, elk steaks from a hunter's freezer, exotic leather cowboy boots, dried shark fins, and intricate carvings made of ivory or bone. Most analysts specialize in certain techniques (such as DNA, morphology, or veterinary pathology) and taxonomic groups (mammals, reptiles, marine animals, etc.), as taxonomic groups may be governed by different laws, and considerations of species' biology and distribution can impact interpretation of analytical results.
Two examples of species protected domestically by the Marine Mammal Protection Act and the Endangered Species Act, the scrimshawed sperm whale tooth, and a package of bacon made from Bryde's whale. Both are protected from international trade by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
The Wildlife Forensics Subcommittee of OSAC focuses on standards and guidelines related to taxonomic identification, individualization, and geographic origin of non-human biological evidence based on morphological and genetic analyses. Kathy Moore, M.S., chair, works for NOAA Fisheries' Marine Forensic Laboratory, and has worked doing wildlife forensic methods development and/or casework for more than 20 years.
With input from members as well as guests representing state, national and international agencies, the subcommittee has completed work on its first document, "Wildlife General Standards", which has been approved by the SAC and sent to the AAFS's Academy Standards Board. Currently, the Subcommittee is working on the following projects:
• Wildlife Forensic Report Writing Standard
• DNA Standards
• Morphology Standards
• Education and Training Standards
• Biology SAC-wide terminology document
