The rising homicide rates in Nigeria underscore the necessity for comprehensive post-mortem interval (PMI) estimations to enhance the reliability of forensic investigations. This study investigates the impact of Marabunta ants (Hymenoptera: Formicidae) on the decomposition process and PMI estimation in pig carcasses during the wet season in Okuku,...

Background and aim: Accurate estimation of the postmortem interval (PMI) remains a critical challenge in forensic investigations due to the complex interplay of decompositional processes. Histo-taphonomy, the microscopic examination of postmortem tissue changes, offers a potential approach for PMI determination. This study investigates the histolog...

This study analyzed the differences in the decomposition patterns and post mortem intervals of hanged and surface carcasses using domestic pigs as human analogues. Six domestic pigs weighing between 25kg–30 kg were separated into two groups comprising three pigs each. Three pigs were hanged on the branches of trees at the research facility; whereas...

Post mortem interval refers to the time taken for a body (carcass) to completely decay; and this begins immediately at death. This timeline is affected by several factors but especially climatic factors. This means that post mortem interval varies from one climate or region to another. Therefore, to determine the factors that affect post mortem int...

Background: Decomposition timeline is the interval from death to complete decay of a carcass. Accuracy in the estimation of this interval helps to confirm the testimony of an alibi or suspect in homicide investigations especially at the law courts. Objectives: This study investigated the early and late visible post-mortem changes of porcine analog...

The assessment of the rate and pattern of decomposition is a basic tool in the investigation of crimes involving death and in forensic practice around the globe. This study is aimed at assessing the pattern of decomposition of porcine carrions in housed and open earth surface environments. This study involved two pigs Sus scrofa domestica) weighing...

Forensic taphonomy is the use of the processes associated with cadaver decomposition in the investigation of crime. Understanding taphonomic process facilitates the reconstruction of events that occur between the deposition of the remains and its discovery, reconstructing ante mortem & peri mortem events and estimation of the post-mortem interval (...

The uniqueness of fingerprints makes it a valued biometric trait and since the prints are regularly seen physical evidence in many crime scenes, forensic investigators employ them for sexual and ethnic differentiations when solving criminal cases. This study was an attempt to discriminate sex and ethnicity using thumbprint patterns and ridge densit...

Flatfoot or pes planus is defined subjectively as a weight-bearing foot with an abnormally low or absent longitudinal arch. It has been observed to be the most common foot pathology not only in patients of all ages in general but in pediatric, orthopedic practice in particular. The medial longitudinal plantar arch has crucial functions in foot biom...

The need to determine PMI is very crucial in clandestine deaths, and insects play quite a significant role is this estimation. After death, a sequence of naturally occurring post mortem changes are immediately activated first, by the actions endogenous microorganisms and later by exogenous necrophagous insects with temperature being a crucial det...

The conditions of Cervical Spine radiographs cannot be assessed by merely evaluating the alignment of bones and cartilages that make up the spine. Various radiographic parameters of the cervical spine including the Inter-pedicular Distance (IPD) and Canal Diameter, can be evaluated for diagnostic and treatment of ailments associated with the Cervic...

This study aimed to derive predictive equations for stature esti- mation using shoe print dimensions of adult Nigerian medical stu- dents in the University of Lagos. A sample of 230 volunteers (100 males and 130 females) of Ni- gerian parentage, aged 18 – 36 years comprised this cross-sectional study. Stature and 460 bi-lateral shoe prints were ob...

Anthropometric measurement of parameters like Facial and nasal indices provides vital information which can be used in plastic surgery and understanding the diagnosis between patients and the normal population. This study was carried out to establish the facial and nasal indices in Idoma ethnic group of Benue state. Four hundred (400) subjects (20...

Identification of an individual using stature is of great significance in forensic practice. With the increasing frequency of natural and man-influenced disasters, it has become imperative for forensic anthropologists to establish population-specific forensic reference standards. This study aimed to derive predictive equations for stature estimatio...

Introduction To analyse and document anthropometric parameters of the normal human auricle among Nigerians of Cross River State origin as well as to evaluate sexual dimorphism and auricular growth variation among the age groups of this population. Methods The present study was carried out on 217 adult volunteers made up of 117 females and 100 male...
