When responding to multiple car accidents, hit and runs, fatalities, and high speed chases, officers can benefit by calling in Crime Scene Officers to assist with the investigation.
While touch DNA has become a much requested and successful test for DNA laboratories to perform, we must remember its limitations and be aware of the factors which may affect the results.
Preserving and maintaining evidence collected at a scene is crucial. The key is understanding evidence and understanding the proper way to package it.
Law enforcement groups are staying ahead of criminals’ ability to conceal information with the use of new data extraction tools.
Gunshot acoustics hold plenty of investigative promise, but analysis can be difficult even for experts.
Here is a behind the scenes look at the science surrounding GSR investigations and the facts that make them dynamic.
Some of the most challenging scenes to process involve suspected arson. Such scenes call for the special expertise of an arson investigator.
Collecting impression evidence is definitely worth the effort—once you do so, you have duplicate evidence that can help make your case.
In this column, we’ll look at some ways to set a high level of professionalism even when you’re watching the bottom line.
Through a local DNA database, Bensalem, Pennsylvania, has begun to leverage DNA in every possible case and has created a truly investigative tool.
Forensic scientists need a dose of yearly education in order to stay informed on modern forensic science. Ideally, hands-on experience along with well-designed lectures would comprise the total learning experience.
Mobile device forensics forecast: continued oscillation, chance of cloud computing.
Laser scanning technology helps investigators piece together a champion boxer’s death.
Geophysics involves the use of a variety of electromagnetic techniques that can be used to outline, discover, and plan an exhumation.
Forensic scientists, police detectives, and other authorities concerned with finding the truth have access to many behavioral identification techniques. The trouble is, these techniques aren’t used nearly enough.
Sometimes the techniques taught in classes and workshops, or the tools or equipment we have at our disposal simply won’t work given the specifics of the crime scene in front of us. When you find yourself in such a situation, you need to think outside the box.
