Thanks to a combination of federal and city funding and a private partner laboratory, 6,600 rape kits have been processed and no longer sit on shelves. Now here’s the scary part. The authorization for Debbie Smith comes to an end next year at a time when it is at the greatest risk of deep cuts in federal funding for backlog elimination.

Forensic laboratories are challenging places to work. This month the Safety Guys alert you to significant physical hazards potentially present in your workplace. What do we mean when we say “physical hazards?” This includes conditions and situations that might lead to slips, trips, and falls as well as the not so obvious hazards such as electrical safety hazards and high noise areas.
This article will examine the impact of the two largest accreditation programs—ASCLD/LAB International for the accreditation of forensic laboratories and the NAME Inspection and Accreditation Checklist for coroner and medical examiner facilities. If you are not currently accredited or are planning a new facility, this will help to address matters to communicate with your design team in order to design with accreditation in mind.

Visible light microscopy techniques are well suited for characterizing the printing techniques of individual characters and to look for evidence of alteration.
In an effort to move the comparison to a more technically reliable validation basis, researchers at the Alabama Department of Forensic Sciences (ADFS) have developed a method for comparing land impressions. The measurement system used in the investigation was an optical profilometry system.
The practice of forbidding smoking, eating, and drinking in laboratories is one of the basic good hygiene practices. Unfortunately, it is often one of the most frequently disregarded. Too many people seem to have a "good reason" for continuing these bad habits.

It's important to develop plans and conduct drills for dealing with emergencies such as fire, explosion, poisoning, chemical spill, vapor release, and personal contamination. The list is incomplete. Let's add bleeding, burns, medical situations, electric shock, and weather emergencies.
The forensic community requires a paradigm shift to include environmental analysis and monitoring of pharmaceuticals and personal care products to prevent serious health and environmental consequences. The risk that these chemical pollutants pose to the environment and human health has been a major concern for environmental scientists and other researchers.
To position a camera for impression evidence photography, place it on a tripod, position the focal plane parallel to the impression, and ensure the camera is at a sufficient distance from the impression to avoid using a wide angle. Wide angle views can create distortion around the edges of the photograph.
Listening is an art and a skill. It requires discipline and focused attention. When you give the gift of silence, you allow others the chance to think and process their thoughts. The time required to do this varies tremendously, depending on whom you’re talking to.
