On Post Mortem
A veterinarian may be asked to examine the remains of an animal. Any remains, even skeletal remains, can provide useful information. Never refuse to conduct a post mortem because the body has deteriorated.
- Perform a thorough necropsy regardless of an obvious cause of death.
- Look for evidence of blood, chemicals, foreign bodies, or accelerants on the coat, mouth, or paws.
- Take radiographs of the whole body. These are important regardless of the cause of death, as healing or healed fractures can establish a history of repeated trauma. In the attached slide, the two top and left bottom photos show old healed fractures (evident callus formation), while the bottom right photo shows recent fractures.
- Estimate the time of death based on gastric emptying, body condition (liver, algor, and rigor mortis) and forensic entomology. (For more information, see M Merck Veterinary Forensics: Making the Case - Proving Cruelty Through Forensics, and also visit http://www.sfu.ca/~ganderso/
- Look for evidence of starvation
- Look for other causes of death in emaciated animals.
- An emaciated animal may have an underlying disease that contributes to its condition and may provide mitigating circumstances for its death.
- Note the loss of external and internal fat. Pericardial and perirenal fat are lost late in starvation. Bone marrow is the last fat lost during starvation.
- Look for evidence of pica in stomach or feces, gastric ulcers, and melena.
- For more detailed information on evidence of drowning, heat stroke, asphyxiation, and traumatic wounds (gunshot and knife) please see The Veterinarian's Role in Handling Animal Abuse Cases : Veterinary Forensics : Making the Case - Proving Cruelty Through Forensics or visit veterinaryforensics.com
