Infos

This richly illustrated two-volume book offers a comprehensive and essential reference guide for veterinary pathologists and clinical veterinarians interested in performing animal necropsies for forensic casework. It presents a broad range of animal crime cases, with particular focus on the post mortem examination and the observed pathology . 
This second volume guides readers through the forensic evaluation of animal deaths caused by drowning, fire, electrical, and environmental injuries, poisoning, animal fighting, neglect, and sexual abuse. In addition, it offers practical advice on evaluating anesthesia-related deaths, age estimation, and how to write the necropsy report.

Jason W. Brooks, VMD, PhD, DACVP, is a veterinary pathologist from the Department of Veterinary and Biomedical Sciences at Penn State University.  As a pioneer in the field of veterinary forensic pathology, he has forged a path toward advancement of the discipline by seeking out advanced training in forensic pathology and crime scene analysis from medical and law enforcement professionals.  He routinely assists law enforcement with animal crimes investigations and strives to develop instructional materials and programs for veterinary pathologists and the law enforcement community.  He conducts research on the estimation of the postmortem interval and the pathology of gunshot wounds and teaches graduate and undergraduate students in pathology and forensic sciences.
