Understand the architecture of a typical Flash Memory Controller. The Flash File System is firmware designed specifically to enable files to be stored in flash memory with each sub-layer performing a specific function. Typical functions include wear-leveling, garbage collection, bad block management, error checking and correction, over-provisioning, reading and writing, erasing, and encryption.
Forensic laboratories are challenging places to work. This month the Safety Guys alert you to significant physical hazards potentially present in your workplace. What do we mean when we say “physical hazards?” This includes conditions and situations that might lead to slips, trips, and falls as well as the not so obvious hazards such as electrical safety hazards and high noise areas.
This article will examine the impact of the two largest accreditation programs—ASCLD/LAB International for the accreditation of forensic laboratories and the NAME Inspection and Accreditation Checklist for coroner and medical examiner facilities. If you are not currently accredited or are planning a new facility, this will help to address matters to communicate with your design team in order to design with accreditation in mind.
Understanding the value of the autopsy report and the information accompanying it is a valuable asset to all investigators. In order to understand the importance of the autopsy report, and how to interpret it, you should understand how other factors influence the report and why you cannot rely on the autopsy report alone.
Questioned document specialists use a wide array of analytical techniques to assist in their investigations ranging from first-line visual inspection tools to advanced chemical-specific analysis instrumentation. Visible light microscopy techniques are well suited for characterizing the printing techniques of individual characters and to look for evidence of alteration.
In an effort to move the comparison to a more technically reliable validation basis, researchers at the Alabama Department of Forensic Sciences (ADFS) have developed a method for comparing land impressions. The measurement system used in the investigation was an optical profilometry system.
The practice of forbidding smoking, eating, and drinking in laboratories is one of the basic good hygiene practices. Unfortunately, it is often one of the most frequently disregarded. Too many people seem to have a "good reason" for continuing these bad habits.
Even with great training and a well-stocked crime kit, most of us will eventually end up at a scene where we run into a problem that we can’t easily solve with the knowledge and equipment we have at hand. When you’re in a tough situation, try to find your own tool of the trade.
Follow these suggestions to be a better and more relaxed manager. Being open to new ideas, available for questions, and able to laugh at yourself go a long way in keeping things in perspecetive and earning your employee's respect.
It's important to develop plans and conduct drills for dealing with emergencies such as fire, explosion, poisoning, chemical spill, vapor release, and personal contamination. The list is incomplete. Let's add bleeding, burns, medical situations, electric shock, and weather emergencies.
The forensic community requires a paradigm shift to include environmental analysis and monitoring of pharmaceuticals and personal care products to prevent serious health and environmental consequences. The risk that these chemical pollutants pose to the environment and human health has been a major concern for environmental scientists and other researchers.
To position a camera for impression evidence photography, place it on a tripod, position the focal plane parallel to the impression, and ensure the camera is at a sufficient distance from the impression to avoid using a wide angle. Wide angle views can create distortion around the edges of the photograph.
Listening is an art and a skill. It requires discipline and focused attention. When you give the gift of silence, you allow others the chance to think and process their thoughts. The time required to do this varies tremendously, depending on whom you’re talking to.

The first responding officer may be called upon to transport evidence from a crime scene.They should be aware that direct sunlight and warmer conditions may degrade DNA, and avoid storing evidence in places that may get hot, such as the trunk of the police car. To best preserve DNA evidence, store in a cold environment.
