Premises for the Identification of Handwriting

With respect to points of similarity in pattern-based evidence, there is a general misconception that exists respecting fingerprint examination. There is no stipulated number of points of similarity that is statistically supported for the identification of a fingerprint, in existence. The International Association for Identification Standardization Committee conducted a 3-year study and concluded that there was no basis for requiring a predetermined number of friction ridge characteristics in order to establish positive identification (Franck 1996).

Enhancing Crime Scene Capabilities with Quadcopter Systems

When working an outdoor crime scene, law enforcement agencies face several concerns. Foremost among those concerns is the need to map or reconstruct a scene; to create an image of the scene for later use; and to mark each and every piece of evidence in a meticulous way. All of this must be done quickly, since in many cases there is an urgency to re-open main traffic routes or public areas. Particularly where car accidents are concerned, a quick accident reconstruction can result in a quicker clearance of the scene. And after leaving the scene, all of that documentation needs to be easily shared with non-agency parties such as officers of the court and service providers, such as insurance agencies.

Editorial: Another Trip Around the Sun

Well, it's 2018, and that can only mean one thing: Evidence Technology Magazine is getting ready to turn 15 years old. While it's difficult to believe that much time has passed, just look at what has changed in a decade and a half:

The 5 Enduring Challenges of Mobile Forensics

The practice of mobile forensics has evolved dramatically over the past 15 years-and, naturally, so have its challenges. As device manufacturers and app developers respond to consumer demand for a better balance between privacy and convenience, forensic examiners face a number of obstacles in retrieving evidentiary data:

NIST Releases Software for Testing Digital Forensic Tools

The National Institute of Standards and Technology (NIST) has released a suite of software to help forensic investigators test the tools they use to retrieve digital evidence from computers, mobile phones, and other devices. When these devices are collected as part of a criminal investigation, the NIST software can help ensure that evidence retrieved from them holds up in court.

Photography of Luminol and Bluestar Enhanced Bloodstains

Investigators have used Luminol to detect latent bloodstains for more than three decades. Luminol is a chemical reagent that reacts to hemoglobin in blood, causing chemiluminescence resembling a blue or violet glow. Bluestar Forensic, a more recent variation, uses a similar chemical reaction to create chemiluminescence. Both have been widely tested and studied and are generally known as the preferred search reagents when the objective is to locate trace amounts of blood. Researchers and practitioners have illustrated the following benefits:

Spherical Image Capture for Crime and Crash Scenes

A New Way to Store Property and Evidence

Get more capacity within your budget and current space

Maintaining a secure chain of custody is key to maintaining the integrity of cases in your community – and the key to maintaining your chain of custody is an organized, well-thought-out evidence storage system. But if your evidence room is already overflowing and funding for a new facility is years away, it can feel impossible to keep your property and evidence room compliant with best practices.


Recovering Latent Fingerprints from Cadavers

IN A HOMICIDE CASE, the recovery of latent impressions from a body is just one more step that should be taken in the process of completing a thorough search. This article is directed at crime-scene technicians and the supervisors who support and direct evidence-recovery operations both in the field and in the controlled settings of the medical examiner’s office or the morgue under the coroner’s direction.
