    Join Here Join or Log in Introduction to Forensic Investigation ​ "Every Contact Leaves a Trace" ​ The fundamental principle of forensic investigation was provided by Dr. Edmond Locard over 100 years ago. But the question remains... How do we find those traces? ​ Here you can learn how traces may be found, what they may look like, or information they may provide. You can also get connected to other great resources in Forensium . ​ This site was created to help anyone interested in learning more about forensic investigation, from the perspective of a crime scene investigator/forensic specialist. In forensics, the learning never stops, and neither should the drive to keep looking for traces, or discovering more ways to find them!

  • FORENSIC ENTOMOLOGY | Mark-Forensics

    Forensic Entomology ​ Entomology is the study of insects, and when that field of study is related to, used in, or connected with a court of law, it becomes forensic entomology. ​ Some of the more common applications for forensic entomology are that it may be used to help determine time of death (postmortem interval), location of death, wound patterns, drug use, or provide other criminal linkage. Postmortem Interval (PMI) ​ As insects which feed on a decomposing body have a predictable life cycle, forensic entomology can aid in determining the post-mortem interval, during an investigation into a suspicious death. ​ One of the most commonly used insects are blow flies (family - Calliphoridae). The blow flies are often the first insects to begin interacting with and feeding upon a decomposing body. ​ Like other insects, the blow flies move through a predictable life cycle, from oviposition (laying of eggs), to emergence as maggots (fly larvae), to a time when they pupate, before emerging as an adult blow fly. Insect Succession ​ Although the blow flies are the first to inhabit a decomposing body, they are not the only ones. There are a number of other insects that are attracted to the body at different stages of decomposition and may aid in determining the post-mortem interval. As the body's decomposition may be affected by a number of external factors -- such as temperature, or exposure to shade or sunlight -- the timing for this succession of insects is variable. Still through a careful examination of the area and context in which the body is found, the insect succession can aid in determining post-mortem interval. More Content Coming Soon ...

  • VIRTUAL SCENE | Mark-Forensics

    Virtual Crime Scene Put yourself into the role of the Forensic Specialist and Crime Scene Investigator. Walk through a crime scene, virtually, and determine what is potential evidence, how would you document, collect, and examine that evidence. What could it potentially tell you, and what are assumptions you may be taking from it, that need to be challenged? Keep in mind, if every contact leaves a trace, what traces are you looking for? Ask yourself: What might be significant? Where might the important traces be? Need a Bit More? Here are some additional crime scene images taken by first responders before they left the area and secured the scene: Overall Images Mid-Range Images ​ Learn More About Forensic Evidence
