Wildlife crime is a multi-billion trade worldwide, with wild birds and their eggs being stolen. To preserve the species, a best practice needs to be established to visualise fingerprints. Fingerprints deposited on to 3 types of eggs/eggshells were treated using development techniques through sequential processes for porous and non-porous surfaces.
This project explored a variety of techniques such as pH testing, FTIR and SEM, alongside statistical tests, in order to establish which method/s were best for the determination and identification of multiple corrosive chemicals and substances, on clothing items from acid attack victims.
This project investigated whether the partial drying of blood drops could aid in the determination of sequence of events of a crime. Ratios between the wet and dry portions of the drops was calculated. The ratios of two drip patterns made at different times were then compared using statistical testing.
This project applied the use of photogrammetry to crime scene documentation, by evaluating different software against each other. Two sets of photographs (one of a room and one of a drinks carton) were run through 5 different softwares to produce 3D models which were used for the evaluation.
Bloodstains on various fabric structures and compositions prior and post laundering using porcine and a hammer. Prior and post laundering stains were measured showing they effected the size and number. Knitted fabrics with larger numbers of loose surface fibres create larger bloodstains, whereas blood does not penetrate tight structures.
Automatic thermal desorption gas chromatography with flame ionisation detection was used to determine migration rates of ethanol, toluene, and decane through nylon, metallised polyethylene terephthalate (PET), and Kapton films for packaging for arson related evidence. Metallised PET was identified as retaining the largest quantity of volatile organic compounds.
When a pedestrian is struck by a vehicle, there are five potential ways they can be thrown. This research investigates if a certain pedestrian throw type can be caused by changing the variables. This was done by replicating vehicle-pedestrian collisions with small-scale reconstructions.
1 in 20 children in the UK are sexually abused. Children don’t typically disclose immediately, leading to evidential loss, therefore alternative evidence is needed. Can tertiary transfer be considered? Semen deposited onto layered material, was examined using common methods to determine if seminal evidence was detectable on tertiary material.
A grading system was created to assess the damage caused to fabrics when exposed to fire. The exposure time, distance, fabric type, and accelerant tested were altered. This was created to determine whether clothing could provide valuable information for fire investigations, as limited evidence is found at these scenes.
The primary aim of the research was to determine the areas on firearms where fingermarks are more likely to be recovered. This information was then intended to inform or develop best practice when police officers come into contact with firearms on duty.
The aim of this project was to determine whether the addition of alcohol, water, aspirin or paracetamol to blood would affect the physical properties of blood causing the angle of impact to be significantly altered, resulting in a change in the interpretation of such blood stain.
Corrosive chemicals of varying concentrations were mixed together with blood. Using the eye and a high-powered microscope the physical and cellular effects the corrosive chemicals had on the blood was identified. This was completed to establish if the effected blood can provide information about an acid attack.
The potential changes of morphological features, appearance and dimensions of textile damage upon different fabrics, were observed after exposure to two water conditions. These features aid in the identification of damage type and thereby, any changes that occur can cause difficulties in identifying the damage type and potential weapon type.
