RECOVER LFT
LATENT FINGERPRINT TECHNOLOGY
RECOVER LFT is a cutting-edge chemical vapor fuming process to develop fingerprints on a range of difficult surfaces including those that have been exposed to extreme heat (discharged bullet casings, for example) and items that have been washed ‘clean’ in an attempt to prevent identification.“This discovery gives us the ability to recover fingerprints from items that would have been previously difficult or impossible. It has shown particularly good results when used on fired ammunition cases, knives and contaminated metallic items” Steve Bleay, MoD Defence Science and Technology Laboratory
Applications
A Compact Laboratory System
Motorized Lid – Offers adjustable capacity.
Operated via the touchscreen, enables development chambers of varying capacity to be used.
Development Chamber – Provides 360o visibility.
Available in 2 sizes, allows the user to monitor the development of fingermarks from all angles.
Precursor Activation Stage – Initiates precursor transition.
Pre-weighed precursor ‘charges’ are placed into the temperature-controlled activation stage.
Integrated System – A turnkey laboratory solution.
Compact and uncomplicated, the RECOVER system takes up a minimal workspace and is delivered ready-to-use.
Touchscreen Interface – Intuitive software design.
User-friendly, icon-driven software reduces complex chemistry to a simple step-by-step process.
Collaborative Effort
Discovered at Loughborough University, developed with the backing and support of the UK Defence Science and Technology Laboratory (dstl), and now, refined by foster+freeman, RECOVER LFT fingerprint technology represents a fantastic example of collaborative working to achieve innovation that will help the police and security services to identify criminals and link them to their crimes.Testing & Evaluation
Today, more than ten years since the initial work on RECOVER first began at Loughborough University, the technique continues to undergo extensive and uncompromising scientific study.FIELD TESTING: The Firing Range
Mixed-calibre ammunition was hand-loaded into a selection of firearms at a Las Vegas gun range. After firing, the shell cases were collected and treated using the RECOVER instrument. Where other techniques have previously had some success at visualizing fingermarks on a low percentage of bullet casings, RECOVER was able to reveal usable marks on the majority of casings examined.IN-HOUSE TESTING: Exploring the Limits of RECOVER
Having produced impressive results on a wide range of evidence types previously considered to be difficult or impossible to obtain prints from, in-house chemists have now moved on to testing the absolute limits of the RECOVER LFT technique. Recent tests have produced high-quality fingermarks on metal plates that have been submerged in harsh chemicals including disinfectants and bleach.Fingermarks on brass that have been submerged in bleach
