I often ask my students which device is more accurate, a Rolatape, a steel tape, a handheld electronic measuring device, a total station, or a laser scanner. Ultimately that is a trick question. It is not that one device is more accurate than another. They all have the potential to measure accurately. This article is going to discuss a review of the various measuring tools used when “hand” measuring a scene.
To determine the amount of light needed in a space, designers turn to the standards developed by the Illuminating Engineering Society (IES).
Once evidence is received into the DNA laboratory, how is contamination minimized and what are the potential sources of epithelial cells?
Sometimes managers feel that people can perform better and can produce more, but if employees have found a comfortable and satisfactory balance it is best not to disturb it. Resist the temptation to over mange them.
It is not unusual for a paternity test to be carried out following the death of the alleged father. Paternity DNA testing is the only way of scientifically establishing whether a given man has biologically fathered a child.
Standard microbiology practices are usually enough to protect laboratory workers and other employees in the building. These include mechanical pipetting only (no mouth pipetting allowed), safe sharps handling, avoidance of splashes or aerosols, and decontamination of all work surfaces when work is complete.
A laser device allows you to measure in almost any unit and resolution. The use of this type of device makes taking scene measurements a one-person job.
Staying away from office politics isn’t easy. Love it or hate it, it’s real, it’s present, and it isn’t going away any time soon. Get used to it, understand it, accept it, and learn to play. Your job, even your long term career, may depend on it.
During the development time of this article and publishing “Part One”; Walmart’s E-Discovery and Forensic Services Laboratory has achieved ASCLD/LAB accreditation. Ken Mohr, a principal at Crime Lab Design, will now continue to explore some of the physical space needs that attributed to the project’s success with Larry Depew whose company, Digital Forensics.US, LLC consulted on the project.
If there is anything that all laboratories have it is bottles and bottles of chemicals. Forensic laboratories are no exception. If we are not diligent in properly handling and storing these hazardous substances, problems are sure to arise. Potential problems run the gamut from minor inconvenience to life threateningly serious.
Proper scene documentation starts with creating a field sketch; one of the most important pieces of the puzzle. A sketch is a rough drawing of the layout of the street or floor plan of the building. The sketch should include roadway widths, etc. or dimensional room data when hand measuring a scene.
Even when you do everything right during the hiring process, you may still be surprised once the employee comes on board. Team dynamics or changing personal circumstances can affect individual behavior and performance.
The way in which an SSD stores data is totally different from how data is stored on a traditional hard drive. To fully comprehend how an SSD functions and provide insight into their forensic examination, it is necessary to understand SSD terminology.
Repetition by definition involves doing things over and over again. In repetitive work, these same types of motions are performed using the same parts of the body in the same fashion, time and time again. In activities such as typing, using a mouse, or referencing paper source documents, the affected muscles, tendons, and joints can be used thousands of times a day, week after week, year after year
Good investigators can keep lots of details in their heads. Great investigators document the details. Remember that a trial may come right away, or it could be years later, after you’ve potentially investigated hundreds more crimes, and after your memory has faded. One way to deal with this problem is to use a checklist to document everything you can about the crime scene.
