OUR LAB'S ORGANIZATION STRUCTURE The Laboratory consists of seven units: The Administration Branch provides managerial and administrative support to the laboratory staff and is organized into five operational units:
Budget/Purchasing and Personnel This unit tracks, balances and projects the Lab's budget, and provides support in purchasing office and analytical supplies and equipment. They also assist staff with personnel matters. Clerical Support In addition to answering incoming calls and greeting visitors, these folks also assist analysts with a multitude of clerical duties including copying, faxing, filing, and more involved duties such as database work and travel planning. Evidence Processing All evidence is handled by this unit which is tasked with providing guidance to investigators on properly submitting evidence; receiving and logging evidence into and out of the Lab's tracking database; and maintaining chain of custody and the physical integrity of items submitted for analysis.
Quality Assurance The lab is accredited by the American Society of Crime Laboratory Directors, Laboratory Accreditation Board (ASCLD/LAB). The Quality Assurance unit provides services which support accreditation standards. Facilities Management The Facility Manager works hard at taking care of the building to make the staff comfortable and happy. The job includes maintaining all mechanical, electrical, plumbing, heating and cooling services, etc., as well as overseeing the grounds keeping crew. The Chemistry Unit uses chemical, and instrumental techniques to identify and compare a wide range of submitted evidence items, including wildlife parts and products and poisons/pesticides.
Common Chemistry determinations carried out by the Laboratory:

The Criminalistics Unit uses microscopic, chemical, and instrumental techniques to identify and compare a wide range of submitted evidence items such as wildlife parts and products, bullets, cartridge cases, shot pellets, fibers, paint, soil, and physical taggants. The Criminalistics Section is organized into three operational units: the Criminalistics Staff, the Firearms Staff, and the Fingerprints Staff.
Common criminalistics determinations carried out by the Laboratory:

The Genetics Unit uses information from protein and DNA analysis to answer questions about unknown samples.
Sometimes law enforcement officials need to identify blood or tissue and have no visual clues to suggest what kind of animal they represent. The Genetics Section uses information from protein and DNA analysis to answer questions about these unknown samples, such as about species, gender, parentage, number of individuals, or whether two samples come from the same individual animal. In addition, questions about where an animal lived or what population or subspecies it belonged to may be addressed. For some of these questions, each species may require a separate research project. Before questions like these can be answered, basic research must be done to satisfy the requirements of both the scientific and legal communities. The amount of work which needs to be done is likely to continue to increase as more and more species become endangered. Common criminalistics determinations carried out by the Laboratory:
The Morphology Unit uses visual and microscopic comparison techniques to identify a wide range of wildlife parts and products back to a family, genus or species source.
The morphology section consists of a herpetologist, an ornithologist, and a mammalogist. Expertise, experience, and reference material currently available allows identification to species of complete specimens of most North American reptiles, amphibians, birds, and mammals. Identification of whole specimens from outside North America is limited to those species present in our ever-changing vertebrate reference collections. The most common services delivered by Morphology involve:
The staff of the section is well-versed on the national and international holdings of vertebrate groups in the Museum community, the scientific literature, and on additional sources for expertise within the area of vertebrate taxonomy and identification.
The difficulty with morphology-based forensic identifications is two-fold:
For more information about the hard science involved, please visit our Science Professionals: Morphology page as well as our Morphology publications, Feather Atlas The Pathology Unit conducts pathological evaluations of evidence that supports law enforcement agent's investigations into illegal killing of protected wildlife.
Trace evidence such as bullets, pellets, stomach contents, etc. may be collected from submitted carcasses and evaluated in other sections of the laboratory in order to assist the pathologist in making a diagnosis or cause-of-death determination. The most common services delivered by Pathology involve:
