Propellant and gunshot residue from three brands of .22 Long Rifle ammunition were analysed by gas chromatography-mass spectrometry. A bespoke data analysis program was developed in Python to generate profiles for the three propellants, which all had distinct chemical compositions. This research lays the foundations for development of a database.
This project was created to help practitioners with the analyses of synthetic fibres and microfibers using polarised light. A database was created which allows for search by the specific characteristics and the optical analyse numbers known as the birefringence.
Previously ESLA has not been used to recover fibres, although they may have been lifted inadvertently during footwear impression recovery. Warwickshire and West Mercia police desired the recovery of fibres by ESLA to be validated as part of their ISO 17020 accreditation.
Perfumes are made up of volatile components which can be readily absorbed by clothing or skin through direct exposure, but does the length of contact and force of contact have an effect on the number of components transferred onto a second garment?
Most studies used animal blood as an alternative for human blood to minimise the risk of spreading infectious studies. The purpose of this research was to compare the effect of aging between animal blood (anti-coagulant) and human blood (whole). Focuses on the main peak intensities of haemoglobin.
This study was developed to test the effects of different surface types on droplets of blood and verify whether the angle of impact calculations work adequately with the effects of the surfaces and determine whether there is a significant difference between the results.
To determine the impacts of transit on blood containing material within exhibit packaging. Evidential items containing blood were placed within paper packaging and transported under differing time durations, recovering DNA from the insides of the packaging and determining whether DNA transfer does occur and if adequate profiles could be obtained.
Five interior car surfaces (leather and fabric headrest, seatbelt, sun visor and suede imitating a steering wheel) were cut to individually fit into a bespoke plastic container. These surfaces were fired using a pistol with a 9mm knall blank ammunition. These were stubbed to analyse the number of gunshot residue recovered
Currently, fibres are only recovered from bodies or garments found in water for less than a week. This project investigated whether the evidential value of fibres remains high after this time. This will positively impact the reconstruction of water-related crimes and could lead to establishing a timeline of events.
This research investigated the likelihood of foreign DNA being found under the fingernails of those who cohabit. While also determining the effect scratching force has on the quantity and quality of DNA retrieved for a forensic setting.
The prevalence of acid attacks is increasing within the UK, however, the research in this area is not. Ammonia, bleach and sulphuric acid have been applied to cotton and analysed using microscopy, pH analysis, Ion Chromatography and Fourier-Transform Infrared spectroscopy to determine the best method to identify the chemical present.
In many criminal cases, variable quality fingerprints have been developed and archived, resulting in a potential stock of evidentially valuable DNA samples. This project aims to determine the ability to recover and analyse trace amounts of DNA found within the tape lifts of fingermarks enhanced with aluminium powder.
