This article provides an overview of some of the latest technology that can be used in finding and collecting evidence.
Abstract
One of the newest products used to find evidence is the RUVIS, a reflective ultraviolet imaging system used to detect unprocessed fingerprints. A reflective ultraviolet imaging system searches for areas that cause an excitation in bodily fluid or fingerprints. This technology is unique, because unlike alternate light sources, ultraviolet can work in ambient light; therefore, officers can investigate crime scenes in either the middle of the afternoon, in open light, or in a completely darkened room. It does not require fluorescence, so officers do not need to treat suspected areas with powders or chemicals as often. This article describes various types of reflective ultraviolet imaging devices on the market. One of the latest trends in the collection of evidence is the gear that is being used. Disposable body covering is increasing in popularity. This protects officers from the dangers of bloodborne pathogens or bacteria as well as what officers carry into and out of the crime scene. In order to preserve the evidence free of contaminants, many police departments are using drying cabinets. In addition to protecting the evidence, it also protects the people working around it. A tool that aids in evidence collection is tweezers with built-in magnifiers. In conclusion, the article advises that as technology and procedures change, it is important to keep an up-to-date standard operating procedure. This will help protect a department's chain of evidence and keep it from being vulnerable to attack in a court of law.
