You can make your job more manageable by paying attention to the fundamentals. One of the most important things you can do is determine the equipment that is essential to your job. As you gain experience and expertise, the list of equipment will certainly grow and include more specialized items.
Most of us know you should attempt to develop latent prints as soon as possible. When latent...

If you’re lucky, you may arrive at a crime scene and find an ideal situation for processing. Usually, though, scenes are not pristine. You may have anything from an unsecured shed to open fields to swamps and ponds. Weather is often a problem. In this issue, I’ll look at fingerprinting essentials in extreme conditions.
Working in forensic sciences will invariably bring you into potential contact with infectious agents. The foundation for safe performance of duties and proper containment is an effective exposure control plan. This article discusses the basic elements of a comprehensive exposure control plan, what each element should contain, and tips on successful implementation.
In recent years we have seen the drug market flooded with new psychoactive substances, often misleadingly termed “legal highs.” The emergence of new compounds is growing year on year, leaving many working in this area floundering under the ingenuity of the market, and the speed at which it reacts.
Laboratory equipment is one of the drivers of the design of a forensic facility. In this article I will review a few pieces of equipment which have changed over time and how lab design has been adapted to meet those changes. I will review a change in the equipment used to compare and analyze firearms evidence, genetic analyzers used in DNA analysis, and a piece of equipment which tests toxicology samples.
Often an examiner will analyze all the digital media only to determine that the probative data was limited to a browser’s history file, an e-mail, a document, the mobile devices’ logs, or an inappropriate graphic video or picture. Finding the critical probative data faster in a cost effective manner while reducing or eliminating case backlogs is going to require a more efficient methodology.
Recently I was training a group of investigators at a large law enforcement agency on wet-vacuum forensic DNA collection. Over the course of our conversation, I learned there were a couple of people who were not overly enthusiastic about introducing a new collection method to the cases. This hesitancy from some didn’t surprise me, but it did get me thinking about how to address it.
Dirt is full of life, microbial life. Although dirt seems to be an inert, lifeless material, one gram of soil may contain up to eight billion living bacterial cells. Grave soil found next to dead and decomposing human bodies is teeming with many microbial secrets that have yet to be uncovered.
With bath salts being a new product with no exact chemical composition, toxicology companies have struggled to produce a detection technique. As many bath salts are made up of a large drug concoction, with current tests only detecting an individual drug and not a variety of drugs, this also decreases the possibility of detection.
Due to the chemicals used to make the drugs and the wastes generated during the “cooking,” clandestine laboratories present significant safety and health risks to law enforcement, forensic scientists, and the public. When a clandestine drug lab is discovered there is a basic three stage approach to move from seizure to a fully restored site.
Hazards of UV do not distinguish between work and home, and in addition to sunlight, UV light sources are found in the workplace including labs, mechanical rooms, and shops. Sources include some biosafety cabinets, certain types of hand-held light sources, transilluminators, crosslinkers, and some laboratory instruments such as spectrophotometers.
Clearly, finding and collecting as much evidence as possible is key. But in doing so, it’s all too easy to contaminate the results. How can we avoid contamination?
Typically, managers dread having to perform employee assessments and experience high anxiety anticipating them. For the employee, too, who is about to undergo a formal performance assessment, the procedure is a high-anxiety producer. So what typically happens is that two very nervous people get together, try to act calm, and just “get through it.”
The sooner every municipality and jurisdiction takes ownership of its own backlog issue and dedicates the appropriate amount of resources to get kits tested, the sooner they can stop worrying about whether some very smart lawyers are going to find a way hold them responsible.
Before ever putting a respirator on, OSHA requires (and it makes good sense) to ensure users are physically capable of wearing a respirator. OSHA 29 CFR 1910.134 states: “Employees that use any respirators including respirators such as air supplied positive pressure face masks or hoods must have a medical evaluation before use.”
In a question-and-answer session with Robin Gall, Ph.D., Senior Product Manager of STARLIMS Forensics product for Abbott Informatics, find out how the latest forensic technologies are helping forensic laboratories improve productivity, efficiency, and quality.
