In terms of crime scene investigations by means of forensic DNA-analyses, burglaries are the number one mass crime in Switzerland. Around one third of the DNA trace profiles registered in the Swiss DNA database are related to burglaries. However, during the collection of potential DNA traces within someone’s residence after a burglary, it is not known whether the sampled DNA originated from the perpetrator or from an inhabitant of said home. Because of the high incidence of burglaries, crime scene investigators usually do not collect reference samples from all the residents for economical and administrative reasons. Therefore, the presumably high probability that a DNA profile belonging to a person authorized to be at the crime scene ends up being sent to a DNA database for comparison, has to be taken into account. To our knowledge, no investigation has been made to evaluate the percentage of these non-perpetrator profiles straying into DNA databases. To shed light on this question, we collected reference samples from residents who had been victims of recent burglaries in their private homes. By comparing the profiles established from these reference samples with the profiles generated from trace DNA, we can show that the majority of the DNA samples collected in burglary investigations belong to the residents. Despite the limited number of cases included in the study, presumably due to a crime decline caused by the pandemic, we further show that trace DNA collection in the vicinity of the break and entry area, in particular window and door glasses, is most promising for sampling perpetrator instead of inhabitant DNA.

Abstract Background DNA profiling has proven to be a valuable technique for identification of individuals in crime. Currently, the technique targets several short tandem repeat (STR) regions in human genome. However, increasing number of samples submitted for STR analysis may lead to delays due to the limited number of experienced analysts who might be available at any given moment and the time taken to complete lengthy DNA profiling procedures. This study was conducted to test the specificity, repeatability, reproducibility and robustness of Investigator® 24plex GO! kit for genotyping of reference samples submitted to the Royal Malaysian Police Forensic DNA Laboratory for DNA database. Material and methods In this study, Investigator® 24plex GO! kit was used to directly amplify STR loci from buccal swab cell of reference samples that had previously been STR typed using GlobalFiler™ Express kit. Capillary electrophoresis was carried out on a 3500xL Genetic Analyser using POP-4® Polymer. Amplified products were assigned to particular STR alleles using the GeneMapper ID-X version 1.4 software. Results Our study shows that STR profiles generated using Investigator® 24plex GO! gave concordance results with those previously obtained using the GlobalFiler™ Express kit. In addition, quality sensors included in the kit are of particular importance for determining the effectiveness of the PCR reaction and help to indicate the nature and quantity of DNA template for PCR amplification. Conclusion The Investigator® 24plex GO! kit is reliable for STR typing of reference samples.

Forensic DNA databases that operate in the zone forming an interface between science and law have the purpose of gathering and processing DNA profiles for the needs of law enforcement and judicial authorities responsible for preventing and combating crime. Therefore, their appropriate functioning is important. On one hand, it improves efficiency of police work and, on the other hand, it has to play a required role in protecting citizen rights and personal data. The National DNA Database has functioned in Poland since 2007. Its effectiveness is correlated with the number of stored profiles. Despite small collection the Database has on numerous occasions proven its high usefulness in solving criminal cases. The possibility of carrying out searches in other countries databases, as well as legislative and organisational undertakings aiming at improvement of the Database operation are gradually bringing effects and result in an increased detective potential of this tool.

Forensic DNA databases constitute a central investigative resource in modern-day criminal justice systems, and agrees to a “conservation of resources”, by expediting the resolution of crime and judicial proceedings via consolidating the evidence or introducing plea bargaining. Quite a number of reports have demonstrated the efficiency of the DNA database in assisting criminal investigation around the world. However, studies are still lacking in Africa, particularly Nigeria on the utilization of DNA database in crime investigation. Therefore, this article provides a first-hand report. In conducting this study, a comprehensive electronic literature search using PubMed, ScienceDirect, Google Scholar, and Google search for similar and related works were used, and all works meeting the subject matter were considered, including; reviews, meta-analyses, retrospective studies, observational studies, organization recommendations, and original articles. Remarkably, the peculiarity of the various forms of crime committed in Nigeria tends to involve or leave behind biological evidence at the scene of a crime. This biological evidence is a key sample for DNA profiling and subsequent storage in a forensic DNA database. Therefore, a National DNA Database has become very necessary in Nigeria.
