TV programmes often exaggerate what forensic science can achieve, but UK researchers are developing powerful new techniques.
Forensic science is at a critical crossroads, caught between the sky-high, unrealistic expectations of its capabilities amongst jurors and the judiciary, and - omitting DNA analysis - the reality that many techniques and technologies are decades old, based on minimal basic science.
There is a vast dichotomy between fictional television dramas where crime scene investigators provide definitive answers in next to no time from minimal trace evidence and the capabilities of real forensics, where samples are often incomplete and analysis takes several weeks. Professor Sue Black is an anatomist and forensic science professional based at the Centre for Anatomy and Human Identification (CAHID) in Dundee.
CAHID is in the process of producing algorithms to automatically generate pattern analysis from 2D images or video imagery. We have all seen examples of the work of the forensic artist who achieves the seemingly impossible by reconstructing a once-living face from the skull upwards.
Craniofacial anthropologist Dr Chris Rynn showed me the technique in his laboratory-cum-studio at Dundee University.
The purpose of a reconstruction is to generate a likeness that will create leads to aid in the identification of an individual. You might imagine that the need for such skills is rare, but in the high-water-table soils of Scotland, bodies that have deteriorated beyond the possibility of identification by other means are relatively common. The manipulation of visual imagery is key in two other aspects of the use of new technology in forensics - the virtual autopsy and in crime scene reconstruction and mapping. Aberdeen-based Return to Scene Ltd (R2S) has developed sophisticated layered-imaging toolkits that represent the corpse and relevant injuries as a neutral 3D model while retaining the anatomical detail of the autopsy in hidden layers. From this it is possible, through a technique called photogrammetry, to determine the height of a suspect from CCTV footage by comparing fixed points such as window ledges, floor tiles and doors against the 360-degree image. The result is an interactive and walkthrough crime scene that can be explored visually but virtually, eliminating visits and possible contamination. In its simplest form it can deliver a visual reference to jurors, avoiding an expensive and time-consuming site visit. Approaches like this can also help in countries where violent crime is rare and police lack expertise in homicide investigations, by permitting remote crime scene access to international forensic experts, who can advise on procedures like appropriate sample gathering and processing. Lars Ebert and his team at the Institute of Forensic Medicine in Zurich, Switzerland, are taking this approach one step further, testing whether Oculus Rift virtual reality headsets could transport an entire courtroom to the crime scene in a 3D reconstruction.
Perhaps even the legendary Sherlock Holmes would have found the concept of some of these technologies difficult to grasp, but the basis for Professor Lorna Dawson’s work at the Hutton Institute in Aberdeen would be surprisingly familiar to the fictional detective, as his creator Sir Arthur Conan Doyle used soil evidence as a plot device in a Holmes book, 30 years before it was ever used in practice. The 2015 Glasgow murder of 24-year-old Irish nurse Karen Buckley illustrates just how far the science of geoforensics has advanced in recent years. As for future advances in geoforensic technology, Dawson believes that DNA information from the microbial component of soils has a great future potential, adding to the arsenal of soil characteristics that can be used to pinpoint a location. Dawson has been brought in to help the investigation team searching for the body of Moira Anderson, an 11-year-old schoolgirl who disappeared in 1957. Britain’s DNA database holds the profiles of more than 3 million convicted criminals.

The national DNA database produces over 2000 DNA matches a month between offenders and a sample from a crime scene or a victim. Ofcom is the independent regulator and competition authority for the UK communications sectors and we are globally respected for the work we do.

It is therefore vital for forensic professionals to educate everyone in the criminal justice system about technology available to them today, as well as its limitations, while also working to develop the underpinning science and technology.
The aim of the new centre is to identify gaps and failings in current forensic practice and to plug them with research. Of the cases where imagery has been judged to be of sufficient quality by the team, 82 per cent have resulted in a change of plea by the defendant, saving time and money in the court system and obviating the need for traumatic court appearances by the victims and family. While cautious that scientists must not run ahead of themselves in the conclusions that can be drawn, Professor Black points out that the technology can also exclude people, which may be especially important in family court situations where uncles, fathers, stepfathers and brothers may all be potential suspects. Once practised using clay to shape and mould the missing muscles over the surface of the bones of the skull to recreate the face, the process can now begin with a CT scan of the skull. Jurors often find it troubling to examine pictures from the morgue, especially where dead children are involved.
A representation of a baby’s body as a 3D mannequin can be used to show a history of old and healed repeat injuries or fractures. First, a 360-degree image of the crime scene is made using a panoramic camera and multiple images are stitched together. The system can also calculate whether a witness could have seen what they claim to have seen from any particular viewpoint in the area. R2S software is a platform on which case information can be collated, managed and presented.

Viewed at all levels it is a complex case management system and is used in murder enquiries. It also delivers a permanent, navigable visual record of that location over time, long after the original crime was committed. Analysis of soil samples from the suspect’s boots using X-ray diffraction identified the mineral components in the soil and narrowed the area where the suspect had been. Compact analytical machines may appear in police stations and mobile crime labs as these are becoming faster, quicker and smaller; though quality control and the chain of evidence would have to be rigorous.
Plus our ability to extract so much information from ever smaller samples is already making it possible to reopen cold cases.
The device uses motors to create forces that push back on the designer’s hand to simulate touch when the cursor interacts with the 3D model in virtual space.
These can then be separated using colour from recent, fatal injuries and be presented graphically to a jury. Embedded markers link to multiple information types such as the location and audio recording of a 999 call, DNA and other trace evidence samples with their attached forensic expert reports, relevant CCTV footage, crime-scene photographs, incident locations and routes travelled by suspects through the scene. When combined with gas chromatography of organic components of the soil, it was confirmed that the suspect had visited a farm in north-west Glasgow, where the nurse’s body was found dumped in a barrel. We had taken this picture on the internet that we think would be one of the most representative pics for ideas to decorate your home.

We took this image from the net that we consider would be probably the most representative pics for nail polish art designs. However, techniques are now emerging that will strengthen the profession and its standing within the court system. Originally developed for video gamers and used to train surgeons in laparoscopy techniques, haptic tools have now found a use in forensic science. After elimination of lens distortion, this allows the creation of a measurement-accurate depiction of a scene.
Overwhelming forensic evidence combined with CCTV footage resulted in Pacteau changing his plea to guilty and being sentenced to life imprisonment with a minimum of 23 years in jail. We find that this kind of visualisation of injury helps the court,” says Laura Fairley, lead forensic consultant at R2S.
