Although the cause of death is rarely in doubt in train-pedestrian fat
alities, the manner of death is often unclear. The distinction between
accident and suicide can only be made after careful evaluation of the
history, scene investigation, autopsy findings, and toxicologic data.
A retrospective analysis of 25 consecutive train-pedestrian fatalitie
s investigated by our office between 1982 and 1992 is reported. The vi
ctims were predominantly healthy, young males. All but one person died
at the scene. The cause of death was massive blunt trauma in 88% of t
he cases. In one case, the sole injury was decapitation. A tissue or b
lood ethanol level greater than 99 mg/dL was detected in 80% of the ca
ses. A total of 60% of the cases involved persons likely to have been
sitting or lying across the railroad tracks: all but one of these vict
ims were intoxicated. The manner of death was determined to be acciden
tal in 92% of our cases. Decapitation by a moving train is an injury h
ighly suggestive of suicide. Massive blunt trauma, especially in the s
etting of ethanol intoxication, was highly associated with accidental
death. Toxicologic analysis is essential in discriminating willful sui
cide from alcohol-induced incapacitation resulting in accidental death
. Homicide, disguised as an accident or suicide, must be ruled out in
all cases. Accurate determination of the manner of death is an importa
nt issue regarding civil litigation and dispersal of insurance benefit
s.
