Determination Of The Trace Elemental Signature Of Drywall Dust And Its Implication As Forensic Evidence, Emilee Holmes
Master of Science in Forensic Science Directed Research Projects
Drywall is found in most homes built in the United States of America because it is cost effective, light weight, and easy to install. Its brittle nature makes it less resistant to impact which can cause dust to form if a force is exerted on it. Airborne dust can settle on anything or anyone around it and can be considered trace evidence for its ability to connect suspects, victims, and scenes; however, this type of dust is not emphasized as trace evidence and is not always collected due to a lack of understanding of their forensic signatures.The seven producers of …

Master of Science in Forensic Science Directed Research Projects
Kratom is a novel psychoactive substance that has gained popularity within the past ten years. Originating from Southeast Asia, the leaves of the Mitragyna speciosa tree contain two principal alkaloids, mitragynine and 7-hydroxymitragynine, that play a key role in opioid-like effects. Twenty-nine kratom products were obtained from tobacco shops in the Richmond, Virginia area, including powders, teas, capsules, extracts, and a carbonated beverage. Samples were analyzed using Direct Analysis in Real Time-Mass Spectrometry (DART-MS) for kratom alkaloids, labeled ingredients, and other possible organic compounds. Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) was used to quantitate aluminum, arsenic, copper, iron, magnesium, nickel, …
