A large study evaluation of evidence types containing offender fingerprints from recorded crimes in North Macedonia from 2005 to 2015.

The Forensic Institute of the Republic of North Macedonia data set of 1,982 offender fingerprint identifications contributing to a conviction for crimes against property, was evaluated and analysed using contingency table statistical analysis techniques, chi-square test, fisher's exact test and post hoc analysis. The data set was based on the forensic and court information available from 2005 to 2015 and pertained to the location, property type and evidence type. Interpretation of the data identified glass components, doors, windows, points of entry, cardboard and other packaging to be the most likely areas for locating offender fingerprints in non-residential and residential properties.

Peptide analysis of mammalian decomposition fluid in relation to the post-mortem interval.

We report the results of a semi-quantitative peptide analysis of decomposition fluid under field-based conditions in the absence of a soil matrix. Sixteen domestic pig (Sus scrofa domesticus) cadavers were used to model human decomposition in trials conducted in the summer and winter months in Western Australia. Physical characteristics were recorded and targeted peptide components of decomposition fluid were analysed using high performance liquid chromatography-triple quadrupole mass spectrometry.

Challenges in the analysis of forensic pathology data relating to homicides in Kosovo from 2006-2015.

The ability to conduct accurate retrospective homicide comparative research is reliant on the publishing of robust studies that assess the specifics of homicides in a standardised manner. To address these matters at the Institute of Forensic Medicine (IFM) in Pristina, Kosovo, the IFM homicide data of the years 2006-2015 was retrospectively studied. In general, there was a year on year downward trend in the number of homicide deaths in Kosovo per 100,000 people, however it was noted that a standardisation method to record homicides in Kosovo has not been developed and as such, the data may not be complete.

The impact of environmental factors on the production of peptides in mammalian decomposition fluid in relation to the estimation of post-mortem interval: A summer/winter comparison in Western Australia.

We report the peptide content of decomposition fluid produced under field-based conditions and in the absence of a soil matrix. Sixteen domestic pig (Sus scrofa domesticus) cadavers were used to model human decomposition in trials conducted in the summer and winter months in Western Australia. Physical characteristics were recorded and the peptide components of decomposition fluid were analysed using high performance liquid chromatography-time of flight mass spectrometry.

Examination of the temporal variation of peptide content in decomposition fluid under controlled conditions using pigs as human substitutes.

We report the preliminary observations of the peptide content of decomposition fluid produced under controlled laboratory conditions and in the absence of a soil matrix. Four domestic pig (Sus scrofa domesticus) cadavers were used to model human decomposition over a four-week trial period; physical characteristics were recorded and the peptide components of decomposition fluid was analysed using high performance liquid chromatography-time of flight mass spectrometry. Preliminary data analysis indicated that a range of peptides were consistently detected across the course of the trial period and 27 of these were common to all four cadavers; 22 originating from haemoglobin.

A pilot study: The effects of repeat washing and fabric type on the detection of seminal fluid and spermatozoa.

In sexual assault cases and more specifically those involving childhood sexual abuse (CSA), victims may have had their potentially semen-stained clothing washed multiple times before a criminal investigation commences. Although it has been previously demonstrated that spermatozoa persist on cotton clothing following a single wash cycle, items of clothing washed multiple times are not routinely examined in these cases because of the assumption that the laundering process would have removed all seminal fluid and spermatozoa. The aim of this study was to examine the persistence of seminal fluid and spermatozoa on a range of fabric types including cotton, nylon, terry towel (100% cotton), polyester fleece, satin and lace which were laundered up to six times.

The evaluation and validation of Phadebas paper as a presumptive screening tool for saliva on forensic exhibits.

The Phadebas Forensic Press Test is routinely used for the detection of saliva. However, assessment of the use of Phadebas paper for this purpose has not been studied extensively. The suitability of Phadebas paper as a presumptive screening tool for saliva on forensic exhibits, was investigated by analysing the following: (1) sensitivity, (2) specificity, (3) effects of temperature on sensitivity and specificity, (4) detection of saliva in mixed body fluid samples, and (5) influence of substrate porosity.
