Forensic entomology plays a critical role in medicolegal investigations, particularly for estimating the minimum post-mortem interval (mPMI) in cases involving advanced decomposition and dismemberment. This case report presents a complex forensic case from Kuala Lumpur, Malaysia, demonstrating the utility of insect colonization patterna in reconstructing perpetrator behaviour. The case involves a 35-year-old female victim who suffered fatal blunt force trauma and post-mortem dismemberment. Her decapitated head was discovered concealed in a bolster, while other severed body parts were hidden within various wrappings in an apartment. Entomological examination revealed a significant disparity in fly colonization across the remains. The head hosted six diverse Dipteran species: Chrysomy megacephala, Chrysomya rufifacies, Chrysomya nigripes, Lucilia cuprina, Hydrotzea spinigera and Sarcophagidae. Conversely, the concealed body parts were colonized by only two species, Ch. megacephala and Ch. rufifacies. This differential colonization indicates the head remained exposed for a longer duration, permitting multiple oviposition events, whereas the perpetrator's activities on other body parts delayed insect access. Based on the developmental stages of Ch.megacephala collected from the head, the mPMI was estimated at approximately five days. corroborating subsequent police findings. The temporal separation in colonization provided a crucial timeline, suggesting sequential processing and concealment of the remains. This case underscores the importance of detailed entomological analysis for providing reliable biological timelines and behavioural inferences in challenging scenarios designed to obscure forensic evidence
