Veterinary Forensics and Hair- Swindon (UK) 22 May 2014
David Bailey teams up with Claire Gwinnet from Staffordshire University to deliver a one-day course on the benefits of animal hair in resolving issues relating to drug exposure, species identification, data base construction, recent animal movement and DNA analysis. David will present results and up to date analysis of the first ever Pit Bull type dog hair database that he is currently constructing.
?This module is an introduction into forensic hair analysis, especially focusing on the forensic applications for Veterinarians. All stages of forensic hair analysis will be discussed from sampling hair from crime scenes to interpretation of hair evidence. Techniques for sampling will be discussed with applied examples, e.g. taking hair for toxicological analysis or for species identification/comparison.
Contamination prevention and sample storage/handling will also be included. The structure and microscopic characteristics of hair will be introduced with examples of different types of hair. Microscopy techniques will be described (including casting and sample preparation) and documentation methods. Methods that can be completed in any Veterinary lab will be highlighted. Animal hair analysis will be discussed including exotic animal hair analysis. Interpretation of hair evidence will be introduced including its positives, its limitations and its use in court. Case studies of different wildlife crime cases will be included. A brief introduction into toxicological analysis of hairs will be given. Practical sessions will be a mixture of animal hair identification including forensic analysis and documentation of a series of different animal hairs and the analysis of mock-up case studies that could be seen in veterinary practice.
Key learning objectives: ?By the end of this module, delegates should be able to:
- Appreciate the wide range of hair evidence that can be left at a crime scene and understand the key principles by which this evidence can be characterized and compared with control samples, reference materials and databases
- Develop practical skills, especially in microscopy, in the analysis of hairs
