Recovering Digital Evidence with Mobile Device Forensics

Dr. Stephenie Slahor Mobile device forensics is an evolving specialty in the field of digital forensics which goes beyond devices that provide simple voice communication and text messaging capabilities. No doubt about it – technology rules the crime scenes involving computers, tablets, external hard drives, smart devices, E-mails, SMS (text messages), social media, the cloud, data, and even electronic medical records. And, within all that lies more technology to retrieve, study, report, and use data for investigations and for the…


New Forensic Science Techniques and Technology

Stephenie Slahor, Ph.D. Like most endeavors in science, forensic technology develops new techniques to solve problems and improve processes. Here are some of those recent examples. Drones Ground-based crime scene analysis can be effective, of course, but adding in the help of drone-mounted assistance may mean better efficiency and speed in analyzing a scene. And, unlike ground-based techniques (i.e., taking photos, creating maps and charts, sketching, laser scanning) which might contaminate a crime scene because someone has to walk through…


Seven Steps to Launching a Successful Police Department Drone Program

James Bushey Starting a drone program is a significant undertaking and may be intimidating if you have no experience launching a new technological program. There are many considerations at every step of the journey – from equipment startup costs to figuring out how many batteries you’ll need and where you’ll operate in terms of airspace. These factors take time and resources, even for experienced operators. Starting a drone program requires dedicated supplies, support and experience. Here, I’ll walk you through…


TRAFFIC SAFETY KNOWLEDGE, SKILLS AND TECH ASSISTANCE

Dr. Stephenie Slahor The NLELP uses multiple tools to reach out to a vast network in support of national, regional and state safety campaigns, sharing traffic safety news, information and more. A few years ago, the National Highway Traffic Safety Administration (NHTSA) and the Governors’ Highway Safety Association (GHSA) jointly created the National Law Enforcement Liaison Program (NLELP – nlelp.org) to enhance the work of state highway safety offices and law enforcement communities. The game plan created the Law Enforcement…


Five Online Challenges Facing Detectives and How to Overcome Them

Johnmichael O’Hare Online sources open a new world of information which can help detectives find threat actors, speed up investigations and protect lives. But, there’s a catch. As part of any successful investigation, police departments must effectively collect, ingest and analyze vast amounts of data. Fortunately, a data management strategy and supporting technologies provide a way to tame the data explosion. These are the top online challenges law enforcement investigators face and how they work around them:  Big Data and…


Scheduling Software Essentials

Lt. Steve Lynk (Ret.) Along with saving you time in developing the initial schedule, your chosen software should make it easier to fill open shifts and ensure proper coverage. Law enforcement administrators have a lot on their plates. From recruiting and training officers, to coordinating meetings and responding to daily disruptions, their list of duties is extensive. Of these, ensuring adequate shift coverage to meet their department’s requirements is one of the most critical. It also can be one of…


Getting an Edge on Online Threat Actors

Johnmichael O’Hare Law enforcement agencies must contend with the proverbial double-edged sword when they attempt to chase down crime in the online world. On one side, threat actors leave a trail of information through Internet activity, social media posts and cell phone use which investigators can track. But, on the other side, those same actors – if sufficiently knowledgeable – can use born on the Web techniques to conceal their activities and evade detection. The same dichotomy also surfaces when…


No More “Dusting for Prints”

Bill Siuru, Ph.D., PE Fingerprints and forensic evidence found at the scene of a crime are two of the most valuable ways to identify a suspect and solve crimes. Current methods for capturing latent fingerprints require physical contact which can possibly damage or destroy the fingerprint, or risk contaminating or destroying the DNA information contained in the fingerprints. Another problem is locating blood spots, gunshot residue and body fluids at the crime scene or on items taken from the scene…


Fighting Crime with ALPRs

Bill Siuru, Ph.D., PE Technology available to fight crime and guard against terrorism and other dangers brings challenges to the expectation of privacy and protection against unreasonable searches and seizures. Data collected by Automated License Plate Recognition (ALPR) systems can enhance law enforcement’s ability to investigate crimes and enforce the law.  However, at times, it also raises concerns that the information collected may be inaccurate; placed into databases shared without restrictions; retained longer than necessary; or used and abused in…


Is Facial Recognition Technology Ready for Prime Time?

Bill Siuru, Ph.D., PE Facial recognition is considered to be the most natural of all biometric measurements by virtue of individuals being recognized not by scanning their fingerprints or eyes, but by looking at their face. Facial recognition could become the future investigative and surveillance tool of choice by law enforcement because it is much more accurate than the human eye in recognizing faces. It is also easy to implement; verification and/or identification of faces can be very fast; and,…
