Information on Procedure for Necropsy
(gathered by APNM)
It is very important to preserve evidence in felony
cases involving animal cruelty. If a felony case involves an animal
who has died, a necropsy (animal autopsy) should be performed and
tissue samples for pathological examination should be taken. Just
like cases involving human death, in court cases involving the prosecution
of an animal case, an Official Cause of Death must be determined.
In cases where the cause of death is not immediately
obvious, very few veterinarians have the advanced training needed
to issue an Official Cause of Death that will be acknowledged by
the courts. The veterinarians at the New Mexico State Veterinary
Diagnostic Laboratory in Albuquerque are Board Certified Pathologists
and are considered experts in their field. They are qualified to
determine an Official Cause of Death. Some veterinarians may believe
they are qualified and will fulfill your request for a necropsy,
but the courts may not consider them sufficiently qualified and
may disregard their opinion.
While, a complete necropsy of the intact carcass
by a board certified pathologist will provide the best chance to
determine the Cause of Death, in some cases a Cause of Death can
also be determined and accepted by the Court if the necropsy is
performed by the local practicing veterinarian and appropriate fresh
and fixed (preserved) tissues are collected and submitted to the
State Diagnostic Lab. Most local veterinarians are equipped to take
tissue samples to send to the State Diagnostic Laboratory.
Timeliness is a very important consideration when
processing forensic evidence. The sooner the veterinarian has access
to the body for examination, tissue samples, and transport, the
better. If the weather is cool the body will provide useable samples
for much longer than if the weather is hot. Even if you suspect
an animal has been dead for more than 24 hours, dont disregard
the forensic evidence. It may still be valuable.
For example, in cases of suspected poisoning,
stomach contents may reveal crucial evidence, even though other
tissues have deteriorated beyond use. Each case may be different
and law enforcement should consult with an expert before proceeding.
Preserving and gathering forensic evidence is
as important in obtaining prosecutions in animal cases as it is
in cases involving humans. Although costs will vary according to
individual cases and the pathology each case may require, rough
costs of a gross necropsy, which does not include virus isolation
or toxicology (the science of poisons), as of January 2000, are:
Dog - $66.00
Cat - $66.00
Horse - $121.00
Sheep or Goat - $33.00
Cow - $55.00
* Toxicological pathology (tests for poisons or
chemical changes in tissue), which may be needed in some cases,
could cost an additional $15 - $55+.
In summary, to make a solid case and gather sound
evidence, it is best to contact the NM State Veterinary Diagnostic
Laboratory to determine the Official Cause of Death and for related
necropsy information in felony cases. To assist law enforcement,
local veterinarians should be familiar with the procedures used
to prepare, process, and arrange transport of the animals
body to the State Laboratory in Albuquerque. Courier services are
often used to ensure timely arrival and are not as costly as one
might think.
