Long-term qualitative analysis of clothing degradation associated with surface-decomposition in Cape Town, South Africa
The effect of clothing on the decomposition process of human and non-human animal bodies has received considerable attention. Yet, little attention has been given to the effect of decomposing bodies on the integrity of carrion-associated clothing globally, with no data from Africa. We conducted a long-term (over three years) micro- and macroscopic qualitative analysis of the degradation of synthetic, natural, and mixed-fiber clothing associated with surface-decomposing porcine bodies in Cape Town, South Africa. Five porcine bodies dressed in seasonally appropriate clothing were surface deployed and allowed to decompose over multiple seasons in the thicketed Cape Flats Dune Strandveld, an environment of forensic interest in Cape Town. Microscopically, the yarns of synthetic (acrylic pullover jerseys), natural (cotton T-shirts), and mixed-fiber (denim jeans) clothing were distorted and degraded within two to six months, one to three months, and one and a half to two years, respectively. Macroscopically, synthetic, and mixed-fiber clothing showed no visible damage after three years and ten months. Conversely, damage in the form of multiple small holes was noticeable on the natural fiber clothing within two to seven months, with complete disintegration of the clothing evident within two and a half years or less. This study is the first to elucidate the degradation of clothing associated with surface-decomposing bodies in Africa. Our findings reveal that the yarns of synthetic, natural, and mixed-fiber clothing associated with surface-decomposing bodies will degrade over time in different ways and can be used as indicators of the minimum time-since-death of clothed deceased individuals.
期刊介绍:
Science & Justice provides a forum to promote communication and publication of original articles, reviews and correspondence on subjects that spark debates within the Forensic Science Community and the criminal justice sector. The journal provides a medium whereby all aspects of applying science to legal proceedings can be debated and progressed. Science & Justice is published six times a year, and will be of interest primarily to practising forensic scientists and their colleagues in related fields. It is chiefly concerned with the publication of formal scientific papers, in keeping with its international learned status, but will not accept any article describing experimentation on animals which does not meet strict ethical standards.
Promote communication and informed debate within the Forensic Science Community and the criminal justice sector.
To promote the publication of learned and original research findings from all areas of the forensic sciences and by so doing to advance the profession.
To promote the publication of case based material by way of case reviews.
To promote the publication of conference proceedings which are of interest to the forensic science community.
To provide a medium whereby all aspects of applying science to legal proceedings can be debated and progressed.
To appeal to all those with an interest in the forensic sciences.
