We outline issues with a recent publication by Mein and Williams (2023), which is primarily based on the morphology and quantification of osteocyte lacunae, microscopic cavities that house cells (osteocytes) which sustain bone tissue in living vertebrates. Using 26 rats (Rattus rattus) of unreported age and sex, the authors propose a method whereby post-mortem bone degradation on a short timescale can be quantified by analysing subtle shape changes of osteocyte lacunae. However, a lack of consideration is given to the natural variation and other biological factors influencing osteocyte lacunar morphology; the proposed diagenetic composition of lacunae is not determined; and the methods employed, including the animal model used, are unfit for the purpose of the study. Given these issues, we believe the conclusions presented by the authors should be treated cautiously and not extended to forensic investigations of post-mortem interval, particularly in humans.

Providing accurate and reliable measures of decomposition is paramount for forensic research where decomposition progress is used to estimate time of death. Mass loss is routinely used as a direct measure of biomass decomposition in ecological studies, yet few studies have analysed mass loss in a forensic context on human cadavers to determine its usefulness for modelling the decomposition process. Mass loss was examined in decomposing human and pig cadavers, and compared with other common decomposition metrics, such as total body score (TBS). One summer and one winter field decomposition experiment was conducted using human and pig cadavers, as pigs are often used as proxies for human cadavers in forensic research. The two measures of decomposition revealed two contrasting patterns of decomposition on pigs and humans, particularly in winter where TBS stabilised at similar values, but mass loss differed greatly. Mass loss was found to be faster in pigs than humans during early decompos
