Forensic Entomology And The Order Coleoptera, Carrie Pratt

Essential Studies UNDergraduate Showcase

Medico-legal forensic entomology is the study of insects to aid in determining time, place, manner, and cause of death. Identification of the postmortem interval (PMI), or the time that has passed since a person has died, is arguably one of the most important pieces of information that forensic entomology can provide. The PMI can be found using either insect developmental rates or entomofaunal succession, the arrival of different insects at a body at different time points.

The largest group of insects, the beetles, is the order Coleoptera, which contains 25% of all animal species. Members of this order are critical …

A Forensic Investigation Into The Possible Origins Of Three Human Skeletons, Jefferson P. Sinnott

Forensic Science Theses

The Anthropology Department at Buffalo State has three human skeletons that have been part of the department’s collection for several years. The origin of the skeletons is currently unknown. Modern DNA techniques coupled with forensic anthropological techniques may now allow us to determine with some certainty the geographic origin of the skeletons. Ancestry, sex, age, and stature were assessed using current anthropological techniques. Afterwards, one tooth from each of the three skeletons was extracted, pulverized and DNA was isolated. Y-STR fragment size analysis of the DNA samples can provide information about the patrilineage of male individuals. Mitochondrial DNA sequencing analysis …

Analyzing Palm Print Shapes With Pressure And Distortion, Whitney Grannan

Honors Theses

While much research exists on latent fingerprints, there is a lack of research on palm prints. This study aims to discover how the variable of pressure affects the distortion of latent palm prints recovered from a crime scene. This study used various development techniques to extract prints from aluminum Coca-Cola cans, white copy paper, and household steak knives. The collected prints were scanned into the AFIX Tracker system and an auto-extract number, based on the number of minutiae points, was generated automatically from the system. These auto-extract numbers were then compared to a baseline, which consisted of an average of …

A Validation Study Of Blueview™ Gunpowder Particle Testing Kit, Hanna Lester

Honors Theses

The examination of gunshot residue is often an integral part of evidence processing. The aim of this preliminary study is to validate the use of the BlueView Gunshot Particle Test Kit in the field. This was done by comparing the results of the presumptive tests using the BlueView Gunshot Particle Test Kit to confirmatory test results using a scanning electron microscope. This study used both collection techniques to collect samples for presumptive tests and confirmatory tests. Gunshot residue samples were collected from the hands after a series of guns were fired, and positive results were obtained from the presumptive and …

Exploring Various Techniques To Process And Identify Latent Friction Ridge Details From Fingers On Semi-Porous Surfaces, Emily Campo

Honors Theses

Numerous terrorist groups in the Middle East have been recently making detonators for IEDs (Improvised Explosive Devices) using items as basic as flip flops. Because of the semi-porous nature of flip flops, military forensic response teams have been unable to find an effective method through which they can identify, process, and lift latent fingerprints from the surface of a flip flop. The present study aims to use three fingerprint principles to formulate a reliable method that can be used for such purposes. This study specifically investigated the potential use of powders and cyanoacrylate fuming as processing techniques. The case study …

Using Pattern Area Ridge Flow In The Three Areas Of The Palm To Determine Classification Trends, Ashton Horton

Honors Theses

Friction ridge skin is only located on the fingers, palms, and soles of feet. These ridges have been used to make identifications since before the twentieth century. These methods may be the basis of scientific testimony in court because of the amount of research that has been conducted in fingerprint identification. Courts uphold these techniques because of three principles behind fingerprint identification: fingerprints are unique because no two are the same, they will not change from the time they are formed in the womb until post-mortem decomposition, and they can be objectively classified using a general classification system. Little research …

Ant Predation Of Blow Flies During Decomposition And Its Potential Impact On Pmi Estimations, Vincent J. Nappi

Student Theses

When an organism dies, the process of decomposition begins and many insects are attracted to the decomposing remains, or carrion, as a prospective food source for themselves, or their offspring. Blow flies (Family: Calliphoridae), in particular, are one of the first insects to discover and colonize a dead body due to the ability to detect a decomposing resource from large distances. As a result, forensic entomologists take advantage of the behavior and developmental cycles of early colonizers to calculate the post-mortem interval (PMI) in order to determine the time since death. However, along with the insects that are attracted to …

Smoke But No Fire: When Innocent People Are Wrongly Convicted Of Crimes That Never Happened, Jessica S. Henry

Department of Justice Studies Faculty Scholarship and Creative Works

Nearly one-third of exonerations involve the wrongful conviction of an innocent person for a crime that never actually happened, such as when the police plant drugs on an innocent person, a scorned lover invents a false accusation, or an expert mislabels a suicide as a murder. Despite the frequency with which no-crime convictions take place, little scholarship has been devoted to the subject. This Article seeks to fill that gap in the literature by exploring no-crime wrongful convictions as a discrete and unique phenomenon within the wrongful convictions universe. This Article considers three main factors that contribute to no-crime wrongful …

Faculty Research, Scholarly, and Creative Activity

Immature Lucilia sericata (Meigen) raised on beef liver, beef heart, pork liver and pork heart at a mean temperature of 20.6°C took a minimum of 20 days to complete development. Minimum development time differences within stages were observed between the meat types (pork/beef), but not the organ types (liver/heart). Daily hyperspectral measurements were conducted and a functional regression was completed to examine the main effects of meat and organ type on daily spectral measurements. The model examined post feeding larval spectral measurements of insects raised on beef liver alone, the effect of those raised on pork compared with those raised …

Hanging By A Thread: Enhancing The Forensic Value Of Dyed Cotton Trace Evidence Through The Application Of Novel Techniques In Fiber Discrimination, Rachel M. Russo

The Pegasus Review: UCF Undergraduate Research Journal

This thesis examines the capability of current techniques in fiber classification such as UV-visible microspectrophotometry (MSP) (for dye in situ and/or extracted) to discriminate between fibers from sources known to be different. When these methods fail to adequately distinguish the fibers, novel alternative techniques'such as pulsed pumped laser-induced fluorescence spectroscopy (LIF) and liquid chromatography-mass spectrometry (LC-MS)'are utilized to provide definitive forensic evidence.

The FBI Dye Extraction Classification and Chromatography Schemes: Forensic Fiber Examination Guidelines provides the methodology used by the majority of crime labs across the United States (Fong, 1984). In the case of cotton fibers'the most frequently encountered fiber …

An Overview Of The Usage Of Default Passwords, Brandon Knierem, Xiaolu Zhang, Philip Levine, Frank Breitinger, Ibrahim Baggili

Electrical & Computer Engineering and Computer Science Faculty Publications

The recent Mirai botnet attack demonstrated the danger of using default passwords and showed it is still a major problem. In this study we investigated several common applications and their password policies. Specifically, we analyzed if these applications: (1) have default passwords or (2) allow the user to set a weak password (i.e., they do not properly enforce a password policy). Our study shows that default passwords are still a significant problem: 61% of applications inspected initially used a default or blank password. When changing the password, 58% allowed a blank password, 35% allowed a weak password of 1 character.

The use of MDRS for these types of samples can be employed for both forensic investigations and adjudications of cases. The method provides insight about the physical and chemical composition of the sample, as well as about manufacturing and sample history. Here, MDRS was …

Is Forensic Science In Danger Of Extinction?, David San Pietro, Brooke Weinger Kammrath, Peter R. De Forest

Forensic Science Publications

Observations of modern day forensic science has prompted asking the question of whether this field is in danger of extinction. Although there have undoubtedly been meaningful advancements in analytical capabilities, we have overlooked several unintended practical and philosophical consequences. This article addresses three main areas of concern: the declining role of the generalist in an era of increased specialization, the role of education in preparing the next generation of forensic scientists, and the implementation of advanced instrumentation with a focus on statistical significance and field deployable instrumentation.

Oil Dries: A New Absorbent Material For Collection Of Ignitable Liquids From Semi-Porous Material, Jessica Sosa

Online Theses and Dissertations

Extraction of an ignitable liquid sample from a semi-porous surface such as concrete is especially difficult. For this purpose, two different solid oil dry absorbent materials, Instazorb and MAXXAbsorb, were researched for use of collection of ignitable liquid samples at a fire scene. These oil dries were spiked with different ignitable liquids (Coleman fuel, gasoline, kerosene, and diesel). Isolation of the ignitable liquid from the oil dry absorbent was accomplished by passive headspace isolation. Data was obtained by gas chromatography coupled with flame ionization detection (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS). Chromatograms obtained from both oil dries …

Qualitative And Quantitative Elemental Composition Analysis Of The Surrounding Pollen Coating Via Icp-Ms, Brandy Voyer

Electronic Theses and Dissertations

Pollen evidence has proven to be a powerful forensic tool to trace a suspect or item to a victim or a crime scene. This is possible because it is microscopic, abundant in nature, resistant to degradation and decay; it presents dispersal patterns that can be used to generate a 'fingerprint' within specific areas, and has illustrated a unique morphology that can be used to classify species. While the pollen grain morphology has been extensively used to characterize the specific species, not much has been investigated as pertains to the coating that surrounds the pollen grain aside from it being categorized …

If I Had A Million Cryptos: Cryptowallet Application Analysis And A Trojan Proof-Of-Concept, Trevor Haigh, Frank Breitinger, Ibrahim Baggili

Electrical & Computer Engineering and Computer Science Faculty Publications

Cryptocurrencies have gained wide adoption by enthusiasts and investors. In this work, we examine seven different Android cryptowallet applications for forensic artifacts, but we also assess their security against tampering and reverse engineering. Some of the biggest benefits of cryptocurrency is its security and relative anonymity. For this reason it is vital that wallet applications share the same properties. Our work, however, indicates that this is not the case. Five of the seven applications we tested do not implement basic security measures against reverse engineering. Three of the applications stored sensitive information, like wallet private keys, insecurely and one was …

Forensic Markers Of Lampricide Toxicity In Oncorhynchsus Mykiss, Chris White

Theses and Dissertations (Comprehensive)

The lampricide 3-trifluoromethyl-4-nitrophenol (TFM) has been used for decades to control invasive sea lamprey (Petromyzon marinus) populations in the Great Lakes, normally with little harm to other fish populations. However, due to the nature of lampricide treatments and the chemical properties of TFM, adverse effects to non-target fishes and non-target mortality occasionally occur. However, investigations of non-target mortality can be complex, particularly if fish deaths are not noticed immediately, due to decomposition of the carcasses. The objectives of this thesis were to expose rainbow trout (Oncorhynchsus mykiss) to TFM in order to: (i) identify forensic markers …

Morphologically-Directed Raman Spectroscopy For Forensic Soil Analysis, Brooke Weinger Kammrath, Andrew Koutrakos, Josemar A. Castillo, Cathryn Langley, Debbie Huck-Jones

Forensic Science Publications

Morphologically-directed Raman spectroscopy (MDRS) is a novel yet reliable analytical technique that can be used for a variety of forensic applications, enabling scientists to gain more information from samples than they obtain using more traditional methods. In soil forensics, MDRS delivers particle size distribution and microscopic morphological characteristics for the particles present, and at the same time allows secure mineral identification. In this article, we explore the benefits of utilizing soil in forensic investigations, and demonstrate the value of applying MDRS. Two case studies illustrate the real-life potential and applications of this technology.
