In order to effectively investigate crimes involving social media, it is imperative that law enforcement understand “how” social media is stored, “where” such information is stored and found, and “how” to obtain such information using forensically sound procedures. Social media requires a different mind-set to traditional investigative and current forensic methodologies.
Forensic field investigators are prime candidates for slips and falls. Processing a crime scene places personnel in proximity to many hazards.
Often at a crime scene, a member of the public or the first responding officer will try to protect the dignity and privacy of the victim by covering the body with whatever sheet or blanket is readily available from a residence or vehicle.

Many companies diligently strive to create attractive incentive programs in an effort to engage and retain staff. Unfortunately, these efforts actually may be counter-productive to accomplishing these goals.
Checklists are great tools for helping you manage complex crime scenes. By using a checklist, you can track the steps you need to take to do your job correctly.
Forensic image processing (FIP) involves the computer restoration and enhancement of surveillance imagery. The goal of FIP is to maximize information extraction from surveillance imagery, especially imagery that is noisy, incomplete, or over/under exposed. FIP techniques can be applied to various types of images, such as retinal images, shoe impression images, UAV (unmanned aerial vehicle) infrared images, and more.
This can be thought of as the measurable actions of employees in relation to safety in their work. Performance measurement should reflect how workers (management and workers alike) are actually doing compared to applicable regulatory requirements and identified corporate goals.
When you find dust fingerprints and footprints, collect them with an electrostatic dust lifter such as the PathFinder.
For nearly 25 years, advocacy groups and legal scholars have been predicting that the day when the DNA features used in forensic identification will reveal predispositions to diseases or behavioral traits is just around the corner. Questions such as these were mooted by a panel at ISHI last October. Although I cannot presume to speak for the other panelists, I can offer three recommendations of my own.
For the next few weeks, we'll present you with a list of commonly found “beastly” employees, with descriptions of their behavior and suggested strategies for coping with them. Mocking Birds will speak authoritatively on any subject— whether or not they know anything about it. They have an overwhelming need to be admired and respected and may not know they’re not experts.
Most people think you can’t get prints from a wet surface, but you can if you use Small Particle Reagent (SPR).

It is not that one device is more accurate than another. They all have the potential to measure accurately. This article is going to discuss a review of the various measuring tools used when “hand” measuring a scene.
