Determining the age of a wound is challenging in forensic pathology, but it can contribute to the reconstruction of crime scenes and lead to arrest of suspects. Forensic scholars have tended to focus on evaluating wound vitality and determining the time elapsed since the wound was sustained. Recent progress in forensic techniques, particularly high-throughput analyses, has enabled evaluation of materials at the cellular and molecular levels, as well as simultaneous assessment of multiple markers. This paper provides an update on wound-age estimation in forensic pathology, summarizes the recent literature, and considers useful additional information provided by each marker. Finally, the future prospects for estimating wound age in forensic practise are discussed with the hope of providing something useful for further study.

In this study, we assessed 30 insertion-deletion polymorphisms (Indels) (Investigator DIPplex® kit) in four Chinese populations (n = 952) and evaluated their usefulness in forensic genetic applications. After the Bonferroni correction at a 95 % significance level (p = 0.0017), there were no deviations from the Hardy-Weinberg equilibrium observed except for the HLD114 locus in the Tibetan ethnic group studied. A high level of discrimination power was observed for the DIPplex® kit in four sample populations (CDP > 0.9999) and the combined random match probabilities (CMP) were in the range of 1.4766 × 10(-11) to 5.2742 × 10(-13). Four Indels have been selected for further analyses as possible ancestry informative single nucleotide polymorphisms. The study support that the Investigator DIPplex® kit provides a powerful supplement to standard short tandem repeat-based kits for individual identification and kinship analysis in the Chinese population.
