    Microsatellite polymorphisms reveal phylogenetic relationships in primates (1995)

    Notes: Abstract We amplified, via PCR, DNA segments from intron 1 of the tyrosine hydroxylase gene (TH01) and intron 40 of the von Willebrand factor gene (VWA) in ten nonhuman primate genera. In humans both introns contain polymorphic microsatellites with tetrameric repeats. Compared to the allelic ranges in human populations relatively short repeat arrays could be detected for the nonhuman primates typed, presumably reflecting an ancient precursor state at both microsatellite loci. Furthermore, our results provide evidence for an association of the average number of repeats present in different primate genera and their divergence time from man. DNA sequencing of VWA orthologues revealed a relatively high variability in the arrangement of repeats in the 5′-repeat arrays, the generation of which could probably be explained by polar mutational events.

    Experimental bloodstains on fabric from contact and from droplets (1997)

    Notes: Abstract The differentiation between contact bloodstains and stains produced by projected droplets on fabric can be crucial in crime scene reconstruction since suspects can explain bloodstains on their clothing by contact with the victim post mortem. Experimental smear and contact pressure stains on three different types of fabric were compared with stains produced by falling and projected droplets (“dynamic” stains) of equivalent size. The morphology of the small stains (0.1–10 μl) was investigated with a macroscope. Characteristic for “dynamic” stains are symmetry and rhythmicity (secondary droplets) of the stain and a zonal drying pattern. Contact stains lack the characteristic features of “dynamic” stains and show a clear impregnation of the material resulting in a blood-soaked reverse side of cambric and cotton and in a paler overall colour. The mode of formation of microstains (blood volume 1 〈 μl) on irregular surfaces (e.g. terry cloth) can be difficult to determine since the rough surface structure and the small blood volume reduce the characteristics of dynamic stains. In these cases, comparison with experimental stains on the same surface material is recommended.

    Criminal anticipation of DNA investigations resulting in mutilation of a corpse (2000)
    Springer
    International journal of legal medicine 113 (2000), S. 247-248

    Notes: Abstract A corpse of a female was found in her apartment in a state of advanced putrefaction. Both hands were amputated, the external genitals were excised and the body parts had been removed from the scene. The subsequent investigations proved that the body parts had been severed post mortem. The cause of death was determined to be manual strangulation. A 33-year-old man later confessed that he had strangled the victim 9 days prior to discovery of the body and that he had had sexual intercourse post mortem. According to the confession, the rational motive for the subsequent mutilation was to eliminate biological stains (e.g. semen inside the vagina, epithelial cells below the fingernails from scratching) suitable for forensic DNA analysis. This constitutes a new type of defensive mutilation intended to prevent the identification of the perpetrator. An increase in the occurrence would be detrimental to the elucidation rate of homicides: in a total of 171 homicides investigated at this institute, DNA analysis of biological stains gave reliable evidence in 45 cases.
