The key to a successful investigation is the ability to quickly collect comprehensive evidence without disturbing the scene. Being thorough can be challenging, especially when you are working under stressful conditions. A single detail can mean the difference between closing a case file or leaving a crime unsolved.  And when the evidence may not be revisited for months or even years, ensuring it will withstand the test of time is crucial.  With digital scene documentation and mapping, you can easily and quickly capture a comprehensive data set that can be revisited anytime in 3D.

FREE Workshop: Fuming Factors for Fantastic Fingerprints

Cyanoacrylate fuming (aka CA fuming or superglue fuming) is widely recognized as a powerful and useful process for the visualization of latent fingerprints on many types of surfaces. Almost nothing in the forensic sciences, however, is less standardized. What is considered standard practice in one laboratory may be a prohibited practice in another. Equipment can range from rudimentary containers to highly sophisticated laboratory cabinets. Results are often varied and erratic and there seems to be no correlation to expense. To achieve optimum results in latent print development using the CA pr ..read more

The human eye cannot see light in the infrared and ultraviolet wavebands of the spectrum. However, the properties of these types of wavelengths make it possible to capture images that cannot be captured using conventional imaging equipment. Examples of some of the types of evidence that can be photographed with infrared and ultraviolet light include: • fingerprints • body fluids • blood • bullet holes • curved surfaces It is important to note that this type of photography cannot be accomplished with normal digital cameras. Manufacturers take steps to prevent infrared and ultraviolet light fr ..read more

Too many times whne processing evidence, we crime scene investigators come to a fork in the road and ask ourselves: Do we process for DNA, or do we process for latent prints? Once we contemplate which process would be best, we hope that we made the most logical decision for catching our suspect. However, there is now a piece of equipment called the Full Spectrum Imaging System (FSIS) that can make that decision process not only simpler but will also give you the ability to process your evidence for both latent prints and DNA. The equipment aids in cutting down on the time it takes to process e ..read more

With so many fingerprinting products on the market to choose from, it can be an overwhelming choice when faced with the task of pulling usable fingerprints from a piece of evidence. Today, we will be discussing magnetic applicators: in what scenarios and on what pieces of evidence are they best used? Magnetic applicators are a great way to dust an area or piece of evidence for fingerprints without over powdering the area in question. An example of this would be a foil chip bag that has been wadded up and has deep groves that need to be examined for prints, or a label on a water or soda bottle ..read more

In crime scene photography, the proof is in the details. A great way to get detailed, comparison grade photographs of evidence is to use a photo macrographic scale. In this article, we will be detailing ABFO NO.2 photo macrographic scales. These come in multiple colors, which include 18% gray, white with 18% gray accents and black which are ideal with proper camera settings. ABFO stands for “American Board of Forensic Odontologists.” The scale was developed by this board in order to properly photograph bite mark evidence for comparison of the human mouth. Bite mark evidence can be transient in ..read more
