With all of the speculation, few have devoted the time and effort necessary to correctly and accurately reconstruct the events of that evening from a neutral point of view. What really happened when George Zimmerman confronted Trayvon Martin? Join us as we take a look at the evidence in the case from the standpoint of a forensic crime scene reconstructionist.
With television shows like Crime 360, the use of three-dimensional computer modeling to accurately depict crime scenes has become popular among forensic science fans around the world. But is this technology just pop-culture entertainment, or is it practical for the law enforcement community? In this article, we discuss some of the current trends and advancements in three-dimensional laser scanning and its impact on forensic investigations.
Developing latent fingerprints on human skin is not an easy task, but successes have occurred.

How does one approach the process of crime scene reconstruction from a philosophical standpoint? In this article, we'll look at how the crime scene reconstructionist must approach his or her job, what must be done, how forensic science applies, and what sort of approach one must take. We'll see how the reconstructionist is limited by the asymmetry of time and how those limitations can be harnessed to define the constraints of the analysis.
In the post-OJ Simpson, post-Daubert, post-NSA world, forensic science is suffering an identity crisis. Is forensic science an applied science or a separate basic science? Where should it fall within the world of education? What steps are needed to move forward. Join us as we take a look at this identity crisis and look for ways for forensic science to move forward.
Have you ever arrived at a shooting scene and found that a bullet had shattered the tempered glass in a side window? The glass was probably making noise, causing you to fear that it was about to fall out. What would happen to the bullet hole if it did? In this article, we'll show you a quick and easy technique for marking the location of the bullet hole so that it can still be used for trajectory reconstruction even if the glass falls out.
Alternate light sources are not a crime scene luxury; they are a necessity. Processing a death scene without an alternate light source is likely to result in missed evidence, and in some cases that missed evidence might prove critical to the case. In this article, we'll discuss the use of alternate light sources for processing crime scenes, and we'll show you a case in which the alternate light revealed some very important evidence on the body of murder victim.
