Imagine a scenario where personal belongings such as pens, keys, phones, or handbags are found at an investigative site. It is often valuable to the investigative team that is trying to trace back the belongings to an individual to understand their personal habits, even when DNA evidence is also available. Here, we develop an approach to translate chemistries recovered from personal objects such as phones into a lifestyle sketch of the owner, using mass spectrometry and informatics approaches. Our results show that phones’ chemistries reflect a personalized lifestyle profile. The collective repertoire of molecules found on these objects provides a sketch of the lifestyle of an individual by highlighting the type of hygiene/beauty products the person uses, diet, medical status, and even the location where this person may have been. These findings introduce an additional form of trace evidence from skin-associated lifestyle chemicals found on personal belongings. Such information could help a criminal investigator narrowing down the owner of an object found at a crime scene, such as a suspect or missing person.

The ability to predict physical characteristics from DNA presents significant opportunities for forensic science. Giving scientists an ability to make predictions about the donor of genetic material at a crime scene can then give investigators new intelligence leads for cold cases where DNA evidence has not identified any person of interest. However, the interpretation of this new form of intelligence requires careful analysis. The responses to an online survey, conducted in 2018-19, were used to examine how actors in the criminal justice system assess and interpret different types of DNA evidence and intelligence. The groups of focus for the survey were investigators, legal practitioners and the general public (as potential jurors). Several statistically significant effects were identified based on occupation and whether an individual had prior exposure to new DNA technology. Monitoring how those involved in interpreting reports from different types of DNA evidence and intelligence interpret them helps to ensure that decisions are made based on a sound understanding of their capabilities and limitations and may inform broader training and awareness strategies.

The author of the article analyzes existing methods of seizing three-dimensional and latent (two-dimensional) shoeprints, described in the forensic scientific literature, which are used in Ukraine and abroad. Attention is drawn to the fact that methods of seizing traces that have been used for a long time are a subject to minor changes, despite the development of scientific and technological progress. The author names a reason for such a phenomenon: the lack of exchange in experience with countries that use modern tools and techniques for forensic analysis, one of which is a crime scene fingerprint film lift pad. The crime scene fingerprint lift pad is most often used when seizing latent (two-dimensional) shoe prints during inspection of a crime scene. However, attention is drawn to the problem of further suitability of seized traces for carrying out forensic examination as well as to peculiarities of storing seized materials. According to the author, trace damage is associated with two groups of factors: removal of a trace with violation of a technique and removal of a trace by means of poor-quality material. The author describes several types of crime scene fingerprint lift pad which is used to seize evidence of trace evidence nature. The author notes that along with the development of technology, trace evidence methods should be advanced as well. There is an urgent need to analyze the market of imported fingerprints, its efficiency, specificity of forensic situations, weather conditions, etc. There is also a need to share experiences in the use of such materials by forensic expert subdivisions. The question as to improving domestic production of fingerprint products, increasing the cost for purchasing high-quality materials also arises. Such an approach will fix the situation with quality of a crime scene processing and collection of evidence which will have a positive impact on detection of crimes and identification of perpetrators. The author emphasizes the relevance of this study and need for new theoretical and practical developments.

Probabilistic Evidence

The sufficiency of DNA evidence alone, with regard to convicting accused persons, has been interrogated and challenged in criminal cases. The availability of offender databases and the increasing sophistication of crime scene recovery of evidence have resulted in a new type of prosecution in which the State's case focuses on match statistics to explain the significance of a match between the accused's DNA profile and the crime-scene evidence. A number of such cases have raised critical jurisprudential questions about the proper role of probabilistic evidence, and the misapprehension of match statistics by courts. This article, with reference to selected cases from specific jurisdictions, investigates the issue of DNA evidence as the exclusive basis for conviction and important factors such as primary, secondary and tertiary transfer, contamination, cold hits and match probability which can influence the reliability of basing a conviction on DNA evidence alone, are discussed.
