E-fits overtaken by newer technology in war on crime

Source: National Cyber Security – Produced By Gregory Evans

The power of the ‘e-fit’ appears to be on the wane after new figures showed that just one of more than 30 images issued by a police force led to an arrest. The technology, which updated photofits originally introduced in the 1970s, may be dwindling as newer technology such as CCTV and DNA analysis is used in growing numbers of police investigations, experts said. Suffolk Police released data which showed it had created 87 computer-generated e-fits in the last two and a half years, of which 31 were made public with the rest circulated internally. In total they led to 10 arrests but only one was made as a result of the images released to the public. It comes after widespread criticism of the quality of some images released nationwide, which included one from Suffolk in April last year which appeared to depict a “ninja” with a black hood and only his eyes visible. • Police defend ‘lettuce-head’ e-fit “We have better ways of catching people these days through CCTV, automatic number plate recognition and DNA,” said David Wilson, professor of criminology at Birmingham City University. “But eyewitness evidence has never been particularly helpful, and its usefulness is one of […]

Until now, DNA left at the scene of a crime only proves useful if it is already stored in a database and can be matched to a suspect. But a team of forensic experts have devised a way to recreate the face of a person, including eye and skin colour, using as little as 50 picograms (0.05 nanograms) of extracted DNA. Called DNA phenotyping, the tests also determine the person’s ancestry, if they have freckles and can be used to match with distant relatives. DNA phenotyping is the prediction of physical appearance from DNA and is a technique being pioneered by Virginia-based Parabon Nanolabs. The technology can be used to generate leads in criminal cases where there are no suspects or database hits, or to help identify remains, for example. Samples can be potentially taken from as little as a fingerprint. Parabon’s Snapshot Forensic system is said to be able to accurately predict genetic ancestry, eye colour, hair colour, skin colour, freckling, and face shape in individuals from any ethnic background. Each prediction is presented with a ‘measure of confidence’. As an example, the test can say a person has green eyes with 61 per cent confidence, green or blue with […]
