RTI SoleWitness: Streamlined Footwear Evidence Collection at Crime Scenes

Explore More RTI Products

Product Overview

RTI SoleWitness is a cutting-edge, forensic mobile app designed to streamline the documentation and collection of footwear evidence at crime scenes.  Many law enforcement agencies struggle with footwear impression evidence collection due to the limited availability of crime scene photographers and specialized DSLR camera equipment. As a result, critical footwear impressions are often under-documented, leading to missed investigative opportunities.

RTI SoleWitness leverages recent smartphone advancements, like high-resolution cameras and LIDAR technology, to empower law enforcement officers, forensic experts, and crime labs to capture high-quality footwear evidence without requiring expensive equipment or extensive training. 


The Story Behind the Footwear Impression Evidence Solution

RTI SoleWitness was developed in response to critical challenges identified by justice and forensic science experts at RTI.  The app simplifies and enhances the process of documenting footwear impression evidence, addressing gaps in standard practices and empowering crime labs, police departments, forensic experts, and research institutions with an affordable, high-impact tool. RTI SoleWitness addresses several challenges in standard practice:

  • Inefficient Evidence Collection: Footwear evidence is critical at all crime scenes, but law enforcement officers often struggle with proper documentation.
  • Need for Training: There is a lack of standardized training for capturing footwear evidence which leads to improper or incomplete data collection.
  • Limited Resources: Many departments lack the budget for crime scene photographers and dedicated photography equipment, restricting evidence collection capabilities.

How RTI SoleWitness Works

RTI SoleWitness™ guides law enforcement officers and forensic teams through a step-by-step process to ensure accurate and complete footwear impression documentation directly from their mobile device. Here’s how the app works:

Create a New Case 
RTI SoleWitness™ allows investigators to start new cases by entering key details such as the case number, evidence ID, and location information. The app uses GPS to automatically fill in the location, with the option to manually adjust it if needed for accuracy.

Capture and Document Footwear Photos
To establish the impression’s relative positioning, investigators take photos from four directions—North, East, South, and West—guided by an on-screen compass for accurate alignment. Six additional close-ups highlight the impression’s fine details, leveraging LiDAR technology to generate images embedded with a photo scale for dimension measurement. Real-time prompts ensure proper lighting, angle, and distance across all photos, providing investigators with reliable and actionable evidence.

Review, Save, and Manage Data 
All captured photos are securely stored within the app, enabling investigators to review and organize each image. Featured tools like tutorials, checklists, and mock cases are avaliable to enhance investigators’ proficiency in the footwear evidence collection process. RTI SoleWitness™ ensures high standards in evidence collection by providing real-time guidance and feedback at every stage.
