P. Betz et al., THE DETECTION OF PETECHIAL HEMORRHAGES OF THE CONJUNCTIVAE IN DEPENDENCY ON THE POSTMORTEM INTERVAL, Forensic science international, 64(1), 1994, pp. 61-67
Petechial haemorrhages of the conjunctivae are not specific for lethal
throttling or strangulation, but they belong to the important indicat
ors for such mechanisms. In experimental models it is shown that petec
hial bleedings of the conjunctivae disappear with the occurrence of ad
vanced signs of putrefaction or in cases of fresh-water logging. There
fore, it must be emphasized that the lack of petechial haemorrhages in
putrefied or fresh-water-logged corpses is of very restricted meaning
for the examination, whether throttling or strangulation has taken pl
ace or not, and the autopsy should always be performed in these cases
with special regard to the neck.
