Genital lacerations following sexual assault and consensual sexual intercourse: A...
The identification of genital injuries during a medical‐forensic examination may impact the investigation and prosecution of sexual assault. The purpose of this meta‐analysis was to compare prevalence of genital lacerations (or tears) in persons reporting consensual versus non‐co...
A statistical analysis for deepfake videos forgery traces recognition followed by a fine...
Deepfake videos are growing progressively more competent because of the rapid advancements in artificial intelligence and deep learning technology. This has led to substantial problems around propaganda, privacy, and security. This research provides an analytically novel method f...
Significance of image brightness levels for PRNU camera identification
A forensic investigator performing source identification on a questioned image from a crime aims to identify the unknown camera that acquired the image. On the camera sensor, minute spatial variations in intensities between pixels, called photo response non‐uniformity (PRNU), pro...
Best Practice Recommendation for the Preparation of Test Impressions from Footwear and...
A Bayesian approach to Suchey‐Brooks age estimation from the pubic symphysis using modern...
A critical component of the biological profile involves accurate estimation of the age‐at‐death of the decedent(s). While bias, inaccuracy, and population specificity have plagued age estimation methods, these issues are minimized by Bayesian statistics. Our primary analysis gene...
The development of two fast genotyping assays for the differentiation of hemp from...
The legalization of hemp cultivation in the United States has raised the need for reliable methods to distinguish between legal hemp and illegal marijuana. Genetic analysis has emerged as a powerful tool, surpassing traditional chemical methods in specific aspects, such as analyz...
Impact of illustrated backgrounds on the automatic assessment of fingermark quality
In the fingermark detection field, background illustrations may negatively impact the visibility of the marks in presence. They can indeed locally reduce the contrast or mask ridge details. When conducting a research project, the choice for plain or illustrated substrates is most...
Relevant propositions for Y chromosome interpretation
The Y chromosomal haplotype is expected to be identical (or close to, depending on the mutation rate) among a male and many of his paternal relatives. This means that often the same evidential value for the DNA evidence is obtained, whether the true donor or one of his close pate...
Forensic‐geology‐based magnetic analysis of beach sediments from the Shimokita Peninsula,...
The occurrences of various illegal activities on beaches require effective geological and environmental investigation methods. Among these methods, the room‐temperature magnetic analysis of soils and sediments represents a nondestructive investigation method for various amounts, ...
Sickle cell trait in non‐firearm arrest‐related deaths of Black persons
The role of sickle cell trait (SCT) in sudden exertional death is well‐recognized in sports and military training. However, it is not yet studied for non‐firearm arrest‐related death (NF‐ARD). With extensive multi‐pronged searches, a large database (n = 1389) of NF‐ARDs was estab...
Score‐based likelihood ratios for barefootprint evidence using deep learning features
As the court put forward higher requirements for quantitative evaluation and scientific standards of forensic evidence, how to objectively and scientifically express identification opinions has become a challenge for traditional forensic identification methods. Score‐based likeli...
Commentary on: Gutierrez RE, Prokesch EJ. The false promise of firearms examination...

Accurate felt‐tip pen brands classification based on a convolutional neural network using...
Ink analysis played an important role in document examination, but the limited dataset made it difficult for many algorithms to distinguish inks accurately. This article aimed to evaluate the feasibility of two data augmentation (DA) methods, Gaussian noise data augmentation (GND...
A fatal case of potassium gold cyanide poisoning
A 77‐year‐old professional gold craftsman ingested a white powder used in goldsmithing, mistaking the powder for a health supplement. He detected a strange taste and immediately fell sick, reported the incident to 911, and was taken to the emergency room. He died approximately 8....
Detection of low‐level fentanyl concentrations in mixtures of cocaine, MDMA,...
Surface‐enhanced Raman spectroscopy (SERS) was utilized to measure low‐level fentanyl concentrations mixed in common cutting agents, cocaine, 3,4‐methylenedioxymethamphetamine (MDMA), methamphetamine, and caffeine. Mixtures were prepared with a fentanyl concentration range of 0–3...

Air DNA forensics: Novel air collection method investigations for human DNA identification
Modern techniques can generate highly discriminatory DNA profiles from minuscule biological samples, providing valuable information in criminal investigations and court proceedings. However, trace and touch DNA samples, due to their nature, often have lower success rates than oth...
Antibiotic beads found with a skeletal example of complications from a hip replacement
During maceration, a string of beads was found near the surgically modified right os coxa and femur of the remains of a 55‐year‐old woman donated to the Forensic Investigation Research Station at Colorado Mesa University. The remains were initially used in the study of decomposit...
