The vector-borne hemoflagellate parasite Trypanosoma cruzi infects seven million people globally and causes chronic cardiomyopathy and gastrointestinal diseases. Historically, T. cruzi was endemic to Central and South America, but is now found throughout the southern United States and across 43 countries globally. There are three . . .  read more

Comparative Subtidal and Supratidal Taphonomic Changes in the Elemental Components of Marine Vertebrate Bones using Energy Dispersive X-Ray Spectroscopy and Principle Component Analysis: Ecological and Forensic Applications

Individuals and agencies of multiple disciplines have evolved interests which result in the studies and research of marine mammals as well as other protected marine dwellers such as sea turtles. Aside from wildlife conservation, a logarithmic increase in interest to these protected animals have been the side effect of trade for profit to fund activities . . .  read more

Bloodstain Pattern Analysis with an Emphasis on Infrared Photography to Visualize Impact and Satellite Spatter on Denim

Correctly classifying bloodstain patterns is a crucial element of providing conclusions in
the field of Bloodstain Pattern Analysis, because the type of bloodstain pattern speaks to how the
bloodstains were created. Very few studies have compared impact spatter specifically to satellite
spatter. The research needs outlined by SWGSTAIN . . .  read more

Cold Case Investigations: A University Initiative

Despite technological advancements and improved methodologies in

forensic science and investigative practices, cold cases are a growing problem in the

United States. Although there has been a surge in interest in solving cold cases due to

advancements in technology, there has been very little research conducted on cold case

investigation methodology. . . .  read more

Necrophagy in Honey bees (Apis mellifera); A Forensic Application of Scent Foraging Behavior for the Protection and Conservation of Endangered Species

Scent training and field detection trials were conducted to determine if honey bee (Apis mellifera) foraging behavior could be employed as a practical application in the location of vertebrate carrion for use in interdiction and recovery efforts of illegally trafficked wildlife. Resource recognition and querying trials consisted of two components. . . .  read more

The Forensic Value of Processed Human Hair Extensions

Three brands of processed human hair extensions were evaluated microscopically and genetically for their probative value in forensic casework.  Microscopic analysis of hair morphology determined that the internal and surface characteristics of the human hair extensions were consistent with human head hair and failed to identify any distinguishing . . .  read more

Research: Method Development and Validation for Drug Identification and Confirmation by LC/MS-MS for Limited-specimen Cases

Driving under the influence of drugs (DUID) cases represent the largest portion of cases handled in most forensic toxicology laboratories.  Blood is a commonly used specimen and is often analyzed using gas chromatography-mass spectrometry (GC/MS).  A common extraction for this method requires two milliliters of blood.  If more than one extraction . . .  read more
