Summary
A portable case enables cyanoacrylate (super glue) fuming within vehicles for serious crime investigations. This method uses the car as a chamber to enhance latent fingerprint detection at crime scenes.
Area of Science:
- Forensic Science
- Chemistry
Background:
- Latent fingerprint detection is crucial in criminal investigations.
- Traditional cyanoacrylate fuming methods can be cumbersome and require specialized facilities.
Purpose of the Study:
- To develop a portable and self-contained system for in-vehicle cyanoacrylate fuming.
- To enhance the practicality of latent fingerprint visualization in crime scene vehicles.
Main Methods:
- A portable case housing a heater, control panel, and cyanoacrylate was designed.
- The system utilizes a hose to deliver cyanoacrylate vapors into the vehicle.
- A suspended vapor diffuser ensures even distribution of fumes within the car, which acts as the fumigation chamber.
Main Results:
- The developed system provides a controlled environment for cyanoacrylate fuming inside a vehicle.
- The portable case integrates necessary components for process monitoring and control, including temperature and humidity sensors.
Conclusions:
- This portable system offers a practical solution for latent fingerprint development in vehicles at crime scenes.
- It enhances the efficiency and accessibility of forensic fuming techniques for law enforcement.
