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.”

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
