Forensic sciences

The widespread use of handheld smartphones and other devices capable of recording audio and video means that user generated recordings (UGRs) are increasingly presented as evidence in criminal investigations. Combined with other recordings from law enforcement systems, home surveillance systems, etc., the availability of UGRs may offer important audio forensic insights. Forensic handling of UGRs requires best practices for assessing authenticity and integrity of the recorded information.

This webinar will focus on the journey through medical marijuana and the decriminalization of hemp with legalization on the horizon in the state of Ohio. We will also focus on the impact that legalization has made in the state of Colorado over the past 10 years. The journey between these two states will demonstrate the challenges and needs for a shift in the analytical approach.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on April 5, 2022, as part of the ASCLD Train the Director Webinar Series.

The NIST Organization of Scientific Area Committees (OSAC) for Forensic Science advances the mission of strengthening forensic practice by facilitating the development of technically sound, science-based standards through a formal standard developing organization (SDO) process. Although, there are numerous challenges facing laboratory managers in implementing standards, OSAC has observed scores of forensic science service providers implement standards listed on the OSAC Registry and has gathered helpful guidance from the experiences of those laboratories.

This webinar provides an overview of the National Institute of Standards and Technology (NIST) National Software Reference Library (NSRL) Reference Data Set (RDS). The NSRL hash set changes to a new format beginning March 2023, bringing several new capabilities into the hands of digital evidence practitioners. Examples shown enable the creation of case-specific hash sets and searches for notable files. A new update process is also demonstrated.

The Phoenix Police Department (PPD) made a department-wide cultural change in evidence handling, screening, and processing strategies in support of Crime Gun Intelligence Center goals. In addition, the Firearms Section of the PPD Crime Laboratory has validated and implemented a 3D topographical Virtual Comparison Microscopy (VCM) system. The presenters will discuss how the addition of 3D VCM technology in the laboratory and the incorporation of 3D technologies into the NIBIN system has bolstered their ability to provide the best results possible to our customers.

This webinar provides a high-level overview of the Dominance, Influence, Steadiness, and Conscientiousness (DiSC) Personality Assessment tool and its application in workplace settings. Attendees learn how DiSC helps identify individual behavioral styles—Dominance, Influence, Steadiness, and Conscientiousness—and fosters better communication, teamwork, and productivity. The presentation explores practical insights into understanding colleagues' unique preferences and adapting your communication strategies for a more effective workplace.

Effective leadership communication plays a vital role in promoting meaningful change within an organization. This presentation explores key principles such as “modeling the way”, “inspiring a shared vision”, and “start with why”. Vision-driven communication requires crime laboratory supervisors to utilize various communication tools while they act as a driving force within the organization, leading their teams to success.

Although iron-based metals are popular for making critical parts of firearms, they are susceptible to corrosion or rust. There is currently little research on how long a firearm can be left to rust before an identification is no longer possible. This project evaluates the effects of rust on the common working surfaces of Glock and Smith & Wesson Sigma firearms.

This webinar covers ideas and strategies to enhance morale among staff in forensic laboratory units. Positive mental health among team members not only fosters a supportive and productive work environment but also increases the overall quality and efficiency of operations. Participants learn practical approaches to address common workplace stressors, improve communication, and promote resilience within their teams. By prioritizing mental health, laboratories can achieve better outcomes while ensuring the well-being of their dedicated professionals.

This training was presented as a part of the National Center on Forensics conference at George Mason University on August 8th, 2023. In this session, FBI Forensic DNA Examiner Amanda Bakker introduces all the most vital concepts of DNA analysis and evidence. For those who aren’t DNA analysts but work in tangential fields such as law enforcement and criminal justice, this session will be incredibly useful for understanding topics such as what DNA is, how it transfers, how it is collected, and how it is analyzed.
