Since only a few cells can be sufficient to obtain useful DNA information to help your case, this list identifies some common items of evidence that you may need to collect, the possible location of the DNA on the evidence, and the biological source containing the cells.
Research at the Forensic Science and Chemistry Research Group at Anglia Ruskin University, Cambridge, UK, is focusing on this concept of alternative NSAID detection with emphasis on non-invasive samples. In forensic science disciplines there is a real consideration of the state or condition of samples pre-analysis regarding the overall detection of trace compounds.
You are infuriated! The situation is out of control and you just don’t have time to deal with it right now. So what do you do? Here are ten steps that can help you resolve workplace conflict. A long term resolution allows all parties to reach a concensus in a rational manner.
Some people respond well in stressful situations and some people lose focus and can make costly mistakes. But why does stress cause many people to have impaired decision making? The survival mechanisms that make up the stress response are very primitive in origin.
Pertaining to the seizure of digital devices, there is some misunderstanding concerning what “executing the warrant within ten days” actually means. Often, investigators will detail what types of computer files they are going to be looking for so as not to run afoul of the Fourth Amendment.
Poor ergonomic conditions and practices cause more losses in terms of employee suffering, lost time, and productivity than most other types of injury in the workplace. We have begun to explore the ergonomic risk factors associated with the use of computers. The take-home message in this issue is “neutral” and “balanced.”
Comparisons of “unlike” exemplars are sometimes employed when evaluating a shod foot impression with a non-shod barefoot impression. The validity of that method is questioned because shoes do not always match the foot in regard to fit and because shoes of different widths and lengths can affect the dynamic anatomical positioning of pedal soft tissue and osseous structures and pressure weight distribution.
Recent research has shown how forensic mycology can aid investigators by connecting a victim and suspect, determining a location, helping define cause of death, deducing interval since death, and discovering whether a body has been moved.
Great managers break every rule perceived as "conventional wisdom" when dealing with the selection, motivation, and development of staff. Most powerful about these findings about successful management is that each “great” manager was identified based upon the performance results he produced in his organization.
Keeping a checklist reminds you to look at everything. It’s insurance that even if you get distracted, you’ll go back and finish the job. You’ll be glad you did it if your case goes to court and you’re questioned about the crime scene.
For the first time in its history the Houston crime lab does not have a backlog of sexual assault kits. Thanks to a combination of federal and city funding and a private partner laboratory, 6,600 rape kits have been processed and no longer sit on shelves. Now here’s the scary part. The authorization for Debbie Smith comes to an end next year at a time when it is at the greatest risk of deep cuts in federal funding for backlog elimination.
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.
