Forensic
Investigation
Methods
Over the past three years, the EBRP Coroner’s Office has
investigated five cases of fatal carbon monoxide poisoning, one
accidental and four suicides.
Carbon monoxide gas cannot be seen, or smelled or tasted. It
does not cause irritation and the person being exposed often does not
know he/she is being poisoned. Carbon monoxide is produced from the
burning of such things as wood, gasoline, oil, natural gas, kerosene
and coal.
Case History
During a
prolonged power outage due to a recent storm, Bill and Kathy decide to
purchase a generator to preserve the food in the freezer and have some
electricity in the house. While Bill is at work, Kathy decides to do
some vacuuming and brings the generator inside the home and starts it
up. Upon his return home that evening, Bill finds Kathy on the floor
of the kitchen, she is cold to touch and stiff. He calls EMS who upon
arrival calls the coroner. The coroner determines that the cause of
death is Carbon Monoxide Poisoning. The manner of death is accidental.
Prevention
Since wintertime
may be a especially dangerous time for carbon monoxide poisoning, the
following information is provided:
-
Gasoline
powered engines fumes are a dangerous source of carbon
monoxide. This includes not only automobile engines but also:
generators, lawnmowers, chain saws, weed “eaters”, and any
small engine.
- Never use a gas range or oven to heat the home.
- Charcoal
grills, camping stoves, camping lanterns should never be used
indoors or in an enclosed tent.
Of course,
all gas appliances and fireplaces should be inspected on a
regular basis to assure proper functioning. Improperly vented
gas heaters or wood burning fireplaces can be hazardous.
- In addition
to these precautions, carbon monoxide detectors are available
commercially.
Signs and Symptoms
Carbon monoxide poisoning include:
- headaches
- dizziness
- shortness of breath
- confusion
- nausea
- fainting
- convulsions
- coma
- death
Forensic Investigation Methods
|
Of course a complete death scene investigation and proper
collection of evidence and the body are essential foundations
for any forensic evaluation.
In carbon
monoxide poisoning, the tissues of the body may appear to be
“cherry red” in color.
The blood
appears abnormally red when drawn for analysis.
Chemical
analysis of the blood reveals an elevation of “carboxyhemoglobin”.
The elevation of this chemical in the blood means oxygen is not
getting to the tissues of the body. This lack of oxygen
availability to the body is what causes the death.
