The University of Leicester, working with Leicestershire Constabulary and the Institute of Legal Medicine, University of Hamburg, recorded the first ever use of the technology on the dead over six months ago.
The purpose of developing the technique is to enable rapid identification of the deceased and would be of particular benefit in cases of mass fatalities.
The research has been submitted for consideration for publication to an international forensic medical journal and has been carried out by Professor Guy Rutty of the East Midlands Forensic Pathology Unit at the University of Leicester; Karen Stringer, Leicestershire Constabulary Fingerprint Bureaux, and Dr E.E.Turk Institute of Legal Medicine, University of Hamburg.
Professor Rutty said: “No matter where one works in the world, the primary purpose of a medico-legal autopsy is the investigation of who the person was, where, when and by what means they came by their death.
“In mass fatality investigations there is a shift of emphasis of the investigative process towards gathering information for the identification of the deceased. Fingerprinting is usually undertaken by scene of crime or fingerprint officers at the mortuary and although the recovery of fingerprints is possible at the scene of death, as with mortuary recovery, to date handheld real-time on-site analysis (near-patient testing) is not available to investigators.”
The researchers made use of a handheld, mobile wireless unit used in conjunction with a Personal Digital Assistant (PDA) device for the capture of fingerprints from the dead. They also used a handheld single digit fingerprint scanner which utilises a USB laptop connection for the electronic capture of cadaveric fingerprints
Professor Rutty added: “We believe that, through conversations with our colleagues throughout the fingerprint world and the failure to identify any previous peer reviewed publication, we have demonstrated the first use of a handheld PDA based biometric fingerprinting device for use for fingerprinting the dead.
“We have also demonstrated the use of a single digit fingerprint unit with the dead, building upon the scanty literature on the use of larger Livescan devices but more importantly highlighting the limitations of such devices to date. We have applied this technology to an actual real case which resulted in a positive identification, the first of its type to have been undertaken in the UK.”
The researchers also tested the technique on ‘live’ candidates and found some interesting results.
Professor Rutty said: “Although prints were acquired in all cases we observed a number of difficulties with the use of the unit which affected its operation and print quality. The quality of the prints depended on the gender and age of the individual with females worse than males; elderly female pads showed more cracking and loss of ridge details than males in the series captured. Greasy fingers or the use of hand creams decreased the ability to capture images. Grease, creams or sweaty fingers lead to the persistence of fingerprints on the scanner pad which caused smudged images or multiple images of later fingers. This was overcome by drying of the fingers with a cloth prior to capture.”

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
