”This discovery gives us the ability to recover fingerprints from items that would have been previously difficult or impossible

Revolutionary New Technology for the Development of ‘Impossible’ Fingerprints RECOVER Bullet Casings Fired bullet cartridges are notoriously difficult to retrieve ‘usable’ prints from. RECOVER can yield fingerprints of an incredibly high quality. Jointly developed by foster+freeman, the MoD Defence Science & Technology Laboratory (dstl), the Home Office Centre for Applied Science and Technology (CAST), and Loughborough University, RECOVER LFT is a cuttingedge technique that uses an innovative chemical vapour fuming process to develop fingerprints on a range of difficult surfaces including...

RECOVER Compact Laboratory System RECOVER semi-automates the complex chemistry required to produce consistently high-quality fingerprints on untreated or cyanoacrylate-fumed items of evidence. Designed, engineered, and refined to provide a simple, low-maintenance solution, RECOVER contains all of the hardware and software components required for fingermark development, within a compact laboratory system. Motorised Lid Adjustable capacity Operated via the touchscreen, enables development chambers of varying capacity to be used. Development Chamber 360 o visibility Available in 2 sizes,...

Visible image of 2 fingermarks on a bullet casing that has been ‘unwrapped’ using the Cylindrical Surface Unwrapper RECOVER Fingermarks from fired ammunition casings Using traditional development techniques, the chances of locating a usable fingermark on a fired bullet casing are so low that many forensic fingerprint laboratories have abandoned the practice of examining this type of evidence altogether. Now, thanks to the unique chemical reaction of the RECOVER LFT process, it is possible to develop high-quality fingermarks on fired ammunition casings as well as other items that have been...

Greyscale image of fingermarks developed on a washed knife blade (enhanced and inverted using DCS5) Visible Illumination RECOVER Fingermarks from items purposely washed ‘clean’ Perhaps the most remarkable aspect of the RECOVER LFT technique is its ability to develop prints on items that have been submerged in liquids, including harsh environments such as bleach, and those that have been purposely washed clean. Unlike other techniques, the RECOVER LFT process does not require the presence of sweat or naturally occurring skin oils in order to develop a fingermark. RECOVER LFT can also develop...

RECOVER Further Testing and Validation Today, more than ten years since the initial work on the RECOVER LFT technique first began at Loughborough University, the process 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 subjected to the RECOVER LFT process. Where other techniques have previously had some success at visualising fingermarks on a low percentage of bullet casings, RECOVER was able to...
