Abstract:

This thesis investigates the forensic detection of re-quantization and re-sampling that often occurs when multimedia content has been tampered with. The detection is based on statistical classification techniques, including Fisher linear discriminant (FLD) and support vector machine (SVM). Successively compressing an image with different quality factors is a typical example of uniform re-quantization. In the first part of the thesis, we investigate the forensic detection of uniform re-quantization for images. Three features are introduced based on the observation that uniform re-quantization (

Abstract:

This thesis examines the use of nail as an alternative biological specimen in forensic toxicology. Nail is a difficult analytical matrix from which to extract drugs because of its tough physical composition, based on keratin. The initial part of the project investigated the use of a cryogenic grinding method for fingernail clippings. Grinding at liquid nitrogen temperatures was found to be an effective procedure and the conditions were optimised to a two or three cycle programme of freezing and grinding. Small particle sizes were obtained of approximate size 1µm. It was established that drugs

Abstract:

The ability to successfully distinguish truthful and deceptive messages within forensic contexts is important to preserve the integrity of the legal system. Research has shown that confession evidence is highly persuasive at a trial level and that false confessions leading to wrongful convictions are problematic within the judicial system.

Therefore, the present safeguards in the judicial system may be inadequat

Benzodiazepines are among the most prescribed compounds for anti-anxiety and are present in many toxicological screens. These drugs are also prominent in the commission of drug facilitated sexual assaults due their effects on the central nervous system. Due to their potency, a low dose of these compounds is often administered to victims; therefore, the target detection limit for these compounds in biological samples is 10 ng/mL. Currently these compounds are predominantly analyzed using immunoassay techniques; however more specific screening methods are needed. The goal of this dissertation wa

Abstract:

Unlike conventional biological samples (blood and urine), hair samples have a much wider detection period and can provide a retrospective timeline of an individual’s drug use. However, the most crucial issue facing hair analysis is the avoidance of false-positive results caused by passive exposure to the drug. Passive exposure could be a result of direct contact with the consumed material or its smoke. This issue is of great concern especially with the drugs that have a greater potential for external contamination. Common examples of these are cannabis and nicotine, two drugs that are by far t

Abstract:

Individual cues to deception are subtle and often missed by lay people and law enforcement alike. Linguistic statement analysis remains a potentially useful way of overcoming individual diagnostic limitations (e.g. Criteria based Content Analysis; Steller & Köhnken, 1989; Reality monitoring; Johnson & Raye, 1981; Scientific Content Analysis; Sapir, 1996). Unfortunately many of these procedures are time-consuming, require in-depth training, as well as lack empirical support and/or external validity. The current dissertation develops a novel approach to statement veracity analysis that is simple

Abstract:

The current study explored the effects of simulated adjustment domains (i.e., partial denial and social desirability) on specialized substance abuse measures in a sample of 104 inpatient offenders with substance use disorders. Results indicated nearly two thirds (57.9%) of offenders successfully escaped detection on the SASSI-4 and InDUC-2R. Further, subtle approaches employed by the SASSI-4 failed to detect unacknowledged substance use by simulators, and the remaining decision rules were redundant and most likely contributed to the false positive rates for non SU offenders. More promisingly,

Abstract:

The aim of this work was to establish an analytical method for the simultaneous detection of five major opium alkaloids in poppy seeds by liquid chromatography-electrospray ionisation-mass spectrometry (LC-ESI-MS). Once opium alkaloids were detected in poppy seeds, toxicological studies were carried out to establish if these compounds were detected in oral fluid (OF) of participants who ingested muffins containing poppy seeds. It is known that the ingestion of poppy seeds has caused positive opiate drug test results and much work has been reported in the scientific literature in the last 20 ye

Abstract:

The manner in which remains decompose has been and is currently being researched around the world, yet little is still known about the generated scent of death. In fact, it was not until the Casey Anthony trial that research on the odor released from decomposing remains, and the compounds that it is comprised of, was brought to light. The Anthony trial marked the first admission of human decomposition odor as forensic evidence into the court of law; however, it was not “ready for prime time” as the scientific research on the scent of death is still in its infancy. This research employed the us
