Railway and aviation deaths
- Topic
In train and air-crash deaths the doctor helps identify the victims, tell whether they were alive and clarify the cause.
What it is
Railway deaths are usually suicides or accidents (people on the track, level crossings, riding on the outside of trains); homicide and placing a dead body on the line are rare but must be ruled out. The injuries are very extensive and can include separation of body segments; where there are overhead lines, electrocution is another cause. In air crashes with many victims, the main task is identification, which relies on forensic odontology, DNA and personal effects. In both, the autopsy looks for signs of life, toxicology clarifies whether alcohol or other substances played a part and, in the crew, the examiner looks for diseases that could have caused the crash.
Key facts
- Identification with many victims follows the disaster victim identification procedure: postmortem data matched against antemortem data.
- Forensic odontology keeps its value even when the body is badly destroyed or charred.
- In the crew, the examiner looks for diseases (for example heart disease) and substances that may have contributed to the crash.
- Risk factors for railway suicide include young age and mental disorders; prevention includes physical barriers and staff training.
- The event affects train drivers, railway staff, emergency services and witnesses, who may need psychological support.
Structure
- Train: injuries from the impact, the passing wheels and dragging; grease and track dirt on skin and clothing.
- Electrified train: electrical marks and arc burns as well as blunt trauma.
- Aircraft: severe polytrauma from deceleration, often with later burns and charring.
Next step: what to do and document
- Collect and number all remains separately, with their position at the scene, for reconstruction and identification.
- Look for and record signs of vital reaction at the wound edges and, if there was a fire, soot in the airway and carboxyhaemoglobin.
- Take toxicology samples (alcohol, drugs, carbon monoxide) from victims and, in an air crash, from the crew.
- In the crew, perform a full autopsy looking for diseases that could have caused sudden incapacity.
- Keep clothing, personal effects and prostheses under chain of custody: they are key to identification.
Test yourself
Think of the answer, then tap the question to see it.
What forensic question is essential when a body is found on a railway line?
Whether the person was alive when struck; signs of vital reaction help rule out a dead body placed on the line.
Which identification method keeps its value even when a body is charred after an air crash?
Identification by forensic odontology, together with DNA.
Which findings show that an air-crash victim was breathing during the post-crash fire?
Soot in the trachea and bronchi and raised carboxyhaemoglobin in the blood.
What causes of death are seen in people riding on the outside of a train?
Trauma from falls or from striking obstacles and, on electrified trains, electrocution by the overhead lines.
