Every CSI needs a good crime scene kit. Take the time to build your own kit. Yes, it will involve more effort on your part, but you’ll save a lot of money and end up with only the things you really need.
Develop a program for dating stored chemicals and for recertifying or discarding them after predetermined maximum periods of storage.
It has now reached the point that it is no longer practical for an examiner to forensically analyze each and every piece of evidence. Depending upon the alleged crime, often the incriminating evidence can be found in an e-mail, a document, the browser history, an SMS, or some other source. This leads to the obvious conclusion that examiners are going to need a new approach to streamline their workflow.
When patrol officers and/or first responders arrive at the scene, they should look for dust footprints by taking a flashlight and rolling it along the floor. If they simply shine it into the room from a standing position, they’re likely to miss the prints. When they find prints, they should mark them with plastic or disposable tent markers.
A manager’s procrastination tendency raises its ugly head, commonly, when planning for a new project. “Paralysis by analysis” becomes the mode of operation—or non operation. As a manager, your job is to get things done. Don't let procrastination keep you from getting there. If you think that procrastination is a problem for you, you have to deal with it.
Before you step under the tape, stop and study the tracks going into and out of the crime scene. Compare tracks to the tread pattern of those at the scene, and take care not to damage any tracks on your way in.
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.
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.
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.
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 prints are deposited on a surface, nearly 99% of the print is composed of water. The water begins to evaporate and the print dries out. For this reason, it is essential to have first responding officers trained in the development of latent prints when no one else is available.
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.
