Portable Advanced 3D Imaging for Footwear and Tire Impression Capture

October 2019

This Webinar presented a fully-automated 3D imaging technology that can capture 3D fine features at approximately 137 ppi (pixels per inch) within a couple of seconds. This technology was tailored for tire and shoe impression capture but with the potential for other evidence collection.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on October 23, 2019.

Footwear Evidence Conclusions: A Discussion of Standards, Recommendations, and Structure

September 2021

This webinar will provide an opportunity to discuss some of the post-SWGTREAD considerations for articulating findings (interpretations, limitations, opinions, and results) as well as a platform to exchange thoughts, consider suggested conclusion structures, and observe examples related to articulating footwear evidence conclusions.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on September 30, 2021. 

Just Forensic Podiatry Supporting Investigations

November 2024

In episode three of our case study season, Just Science sat down with Dr. Michael Nirenberg, a clinical and forensic podiatrist and current president of the American Society of Forensic Podiatry, to discuss how analyzing a perpetrator's gait and footprint evidence located at a crime scene can help advance investigations and resolve cases.

Just Footwear Impressions on Fabric

November 2023

In Episode eight of our case study season, Just Science sat down with Brian McVicker, a forensic footwear and tire examiner at the Federal Bureau of Investigation, to discuss developing shoe and tire impressions on fabric using ninhydrin. When a victim is stomped or run over the transfer of skin cells onto the inside of the victim's clothing can leave an impression of the shoe or tire that was used.

Just Footwear Forensics to Further Investigations

October 2023

In episode three of our case study season Just Science sat down with Laura Matson an advanced latent print and footwear examiner in the Wisconsin State Crime Laboratories to discuss the value of providing footwear investigative leads. Footwear impressions are commonly found in crime scenes. However, these impressions can be difficult to detect and collect, which leads to the under-utilization of footwear evidence.

U S National Footwear Database System Feasibility Study

February 2022

The FBI Laboratory conducted a comprehensive study known as the National Footwear Database Evaluation. The purpose of the study was to determine the feasibility of developing and implementing a national footwear database system to generate criminal intelligence for law enforcement and serve as a tool for forensic science researchers. This webinar will highlight the team's findings, conclusions, and recommendations. T
