Other Work Products

  • Trace Materials Crime Scene Investigation Guide. The Trace Materials Crime Scene Investigation Guide was developed by OSAC's Trace Materials Subcommittee. The guide assists crime scene teams and law enforcement officers by providing guidance on recognizing, collecting, packaging, and preserving suspected trace evidence. The guide provides detailed and illustrated chapters that each focus on a specific type of evidence.
  • Trace Evidence Collection Mobile App. The Trace Evidence Collection App is a mobile app companion to the Trace Materials Crime Scene Investigation Guide. The mobile app enables the user to access, search, and reference the guide's contents at any time and in any location. With this information easily accessible, users can reference descriptions of different types of trace evidence, information about where trace evidence might be encountered in crime scenes, and instructions outlining the collection and packaging of trace evidence.  
    • These videos, demonstrating various evidence collection techniques, were produced by the Research Triangle Institute (RTI) through the support of the National Institute of Standards and Technology (NIST) Financial Assistance Award Number 70NANB21H098.

  • Forensic Soil Evidence Collection Training Video. The former Geological Materials Subcommittee, in collaboration with the University of Kentucky, the FBI, and the IUGS-Initiative of Forensic Geology have developed a Forensic Soil Evidence Collection Training Video to accompany ASTM E3272-21, Standard Guide for the Collection of Soils and Other Geological Evidence for Forensic Applications (on the OSAC Registry)Learn more about this project by reading our news story.  

Interlaboratory Comparisons

  • In the summer of 2020, the Trace Materials SC conducted an interlaboratory data collection exercise to evaluate the draft of its Standard Practice for Interpretation and Report Writing in Forensic Comparisons of Trace Materials, with the first round of the study focusing on forensic paint analysis. The document is currently under revision (OSAC 2022-S-0029) and the draft used for the interlaboratory study is here
