title: The evidential value of singed hairs in arson cases.
abstract: The prevalence of singed hairs on hands was examined in a representative sample comprised primarily of Hamburg LKA staff members to determine the evidential value of such traces in criminal cases. Hair samples were taken from the hands of 160 subjects and examined under a microscope. Evidence of singing was found in 53 of the samples. These traces were largely restricted to a limited number of areas. Distribution of singed hairs over a wide area was observed in just 3 subjects all of whom reported contact with an open flame. The presence of singed hair on the back of the hand can be of great evidential value, though the corresponding distribution pattern must be carefully interpreted.
