However, to support evidence-based reconstruction of the course of activities having taken place at the scene, contextualising information regarding how and when a biological trace was deposited is oftentimes required. Here we present the development of a forensic molecular biological analysis procedure for the prediction of the time-of-day at which a bloodstain has been deposited by targeted quantification of selected mRNA markers. Time-of-day candidate prediction markers with diurnally rhythmic expression have previously been identified by whole transcriptome sequencing. Here, we build on our previous findings by establishing a targeted cDNA sequencing protocol on an Ion S5 massively parallel sequencing device for the targeted gene expression quantification of 69 time-of-day candidate prediction markers. Based on expression measurements of these markers in 408 blood samples (from 51 individuals deposited at eight time points over a day), we establish and compare different statistical methods to predict time of deposition. The most suitable model employing penalised regression achieved a root mean squared error of 3 h and 44 min with 78 % of predictions being correct within ± 4 h (evaluated by five-fold cross-validation), showing pronounced inter-individual differences. While the prediction accuracies of the method in its current state limit its use in the evaluative stage of a criminal trial, the method may nonetheless provide valuable information in the investigative phase.

This can be evidenced by the large number of population genetic studies that have presented short tandem repeat (STR) data for a wide range of population groups worldwide. However, comparatively little effort has been invested in the measurement of population substructure at various geographical levels and in the investigation of its effect on genetic relationship testing. The concept of population substructure is utilized as a proxy for co-ancestry in kinship calculations and is often corrected for by introducing the co-ancestry coefficient theta (θ). In practice, it is frequently assessed at the national level or for entire subpopulations. However, infrastructure, geographic and sociocultural factors have the potential to significantly impact the estimation of co-ancestry at the local level, leading to larger population substructure in smaller local communities, which may not be adequately addressed by large-scale population studies. Consequently, it can be challenging to accurately estimate the appropriate degree of co-ancestry for a specific genetic relationship testing case. In contrast to the calculations of DNA match probabilities in forensics, there is no conservative approach to account for this uncertainty in genetic kinship testing. In the present paper, we demonstrate that the incorrect choice of the theta correction factor for co-ancestry can have a substantial impact on the outcome of the calculations and therefore potentially on the life of the concerned individuals.

Research on the forensic analysis of eDNA has largely been on bacterial and fungal DNA recovered from soil. In this feasibility study, we sought to determine whether DNA from bacteria, fungi, plants, and arthropods individually or in combination were stable to permit sample-to-sample comparisons between study sites regardless of spatial and temporal variables, as well as mock evidence variability. Mock soil and dust evidence was collected from two sites in Raleigh, NC (USA) over a one-year period. Using DNA metabarcoding we found that a) bacteria, fungi, and plants alone or in combination could differentiate between soil and dust mock evidence and between mock evidence from the two study sites, as the taxonomic communities were significantly different, and b) DNA recovered from plants were consistent between dust mock evidence items over the one year period. In general, total genomic DNA concentrations from soil were significantly higher compared to dust, and soil taxa were more taxonomically diverse compared to dust taxa. We also identified biases in amplification of plants, supporting the need of multiple primer pairs in DNA metabarcoding analyses to capture the full taxonomic diversity within samples.

This study evaluates the application of the International Society for Forensic Genetics (ISFG) recommendations concerning the formulation of such propositions across 15 laboratories in six countries and examines how evaluations are conducted when two persons of interest are considered. They were asked to assess results considering propositions about the source of the DNA during an interlaboratory comparison organized by the French Speaking Working Group of the ISFG. This article focuses on a DNA mixture from a mock case involving a complainant and two persons of interest. Seven of the eight ISFG recommendations were applicable to this interlaboratory comparison, with six being implemented by all laboratories. However, when two persons of interest were submitted for comparison without further case information, only seven laboratories followed Recommendation 3 by assigning a different likelihood ratio (LR) to each potential contributor. One of them used multiple propositions (more than two mutually exclusive propositions) and considered that each person, in turn, could or could not be the source of the DNA with or without the other person. The eight remaining laboratories assigned only one LR considering that both persons were contributors, or neither. As stated in the ISFG recommendations, such a practice should be avoided as it could lead to an overestimation of the LR for one of the contributors. We also demonstrate the effect of considering, or not, the presence of the DNA of persons whose contribution to the DNA mixture was not disputed (i.e., \"conditioning\" the DNA results on the DNA profiles of the undisputed source) on the LR. When conditioning is applied in ground truth experiments, the results provide stronger support for the proposition known to be true compared to the alternative. More precisely, the LR increased by a factor of 100–10’000 when conditioning, depending on the laboratory. The LRs assigned in two real cases are presented to illustrate the need to consider new information, such as the presence of a potential contributor to a DNA mixture, when evaluating results, and multiple propositions when several persons of interest are considered.
