DNA typing was carried out on epithelial cells which were transferred from the hands of the suspect onto the neck of the
victim. In an experimental study 16 suspect-victim combinations were investigated for estimating the typing success. Alternatively
to an attack against the neck, the upper arm was used for “strangulation”. PCR typing was carried out using the short tandem
repeat systems (STRs) HumCD4, HumVWF31A (VWA) and HumFIBRA (FGA) and the success rate was > 70% for all 3 systems. In most
of the cases mixed patterns containing the phenotype of the suspect and the victim were obtained. In a case where strangulation
was the cause of death, epithelial cells could be removed from the neck of the victim. The DNA pattern of the suspect could
be successfully amplified using four STRs, demonstrating the applicability of this approach for practical casework.
