Reconstruction of Forensic Road Traffic Accidents (RTA) often relies on physical evidence such as tyre marks, skid marks, deformation patterns on vehicle, electronic vehicle data, and witness statements. In some rare road accident investigations, however, conventional indicators of vehicle speed are insufficient and making reliable accidence reconstruction challenging. Under such circumstances, the application of classical mechanics provides a scientific theory for determining the motion…

Glycans are a relatively underexplored class of structurally diverse and biologically informative molecules in forensic biology. Glycan structures are generated through complex enzymatic pathways and can vary by cellular origin, tissue type, biological state, and individual characteristics unlike DNA and proteins. Their possible forensic significance is not restricted to their occurrence in biological matrices, since environmental conditions after deposition may influence their persistence,…

Forensic biology has traditionally been based on the use of DNA profiling as the primary method for human identification and biological evidence analysis. While conventional Short Tandem Repeat (STR) profiling is highly reliable for individual identification, it alone cannot address several important forensic questions, including the biological origin of a sample, the age of the contributor, tissue or body-fluid identification, environmental association and aspects of crime scene…

As an introduction, LLLT (Low-Level Laser Therapy) is a physical therapy modality whereby it acts by inducing a photochemical reaction in the cell, a process referred by Professor Hamblin of Harvard as “photobiomodulation” Photo-biology works on the principle that when light hits certain molecules called chromophores, the photon energy causes electrons to be excited and jump from low-energy orbits to higher-energy orbits. LLLT not only energizes the injured cells, but improves…

As one of the most commonplace forms of trace evidence uncovered at crime scenes, human hair serves as a critical biological link during violent physical encounters. Historically, forensic trichology relied on microscopic evaluation-a technique invaluable for ruling out suspects but incapable of absolute individualization. However, integrating Polymerase Chain Reaction (PCR), Short Tandem Repeat (STR) profiling, and mitochondrial DNA (mtDNA) sequencing has revolutionized hair analysis,…

Forensic DNA analysis is an enormous field that rapidly evolves and increases, which highlights a various number of disciplines such as biology, genetics, instrumentation. homicide, biophysics, statistical, recombinant DNA technology and more, that aims to resolve legal matters which revolves around rape, murder, robbery, paternity dispute or identification of human remains. A subfield of forensics is Criminalistics which includes the application of principle of branch of sciences like…

Background: Forensic microbiomics is an emerging discipline that investigates the use of human associated and environmental microbial communities as complementary sources of forensic evidence. The recent development of next-generation sequencing, metagenomics, bioinformatics and computational biology has expanded the possibility to use microbiome analysis for forensic investigations, providing valuable biological information beyond conventional DNA…

Crime scene management forms the cornerstone of forensic investigation, directly influencing the integrity, admissibility, and probative value of physical evidence. Improper scene handling can irreversibly compromise investigative outcomes. This narrative review discusses the theoretical foundations, procedural frameworks, and practical dimensions of crime scene management, integrating established forensic principles with field observations from operational experience at a regional forensic…

Youth crime is a growing national concern in Uganda, reflecting global patterns and country-specific social and economic pressures. This article presents the first comprehensive national overview of youth and juvenile crime from 2017–2024, drawing on Uganda Police Annual Crime Reports, JLOS data reports, and complementary statistical sources. Offences committed by young people aged 12–18 and 18–30 including theft, drug and substance abuse, assault, burglary, robbery, and sexual violence have…
