|Abstract:||This paper assesses use of the EvoFIT facial composite system by police practitioners in the UK and overseas. Results reveal that this forensic system is used extensively: a total of 2,440 times since September 2013. With a suspect identification rate of 60% and a conviction rate of 17%, the impact of this forensic technique is appreciable for helping the police to identify offenders. It was also found that empirically-driven enhancement techniques were used frequently by police practitioners-including use of detailed context reinstatement and holistic techniques during interview, and asking the witness to focus on the eye-region during construction. Research evaluating EvoFIT images published in the media also revealed that composites were produced mostly for serious offences, in particular for sexual crimes. In addition, the vast majority were of male offenders, in their early 30's; victims were female (aged mid 20's to mid 30's); these demographics were similar to composites emerging from another recognition system, EFIT-V / 6. Although this exercise revealed that EvoFIT composites were sometimes published using a more optimal stretched mode, some were presented in a way that did not faithfully represent the constructed image, with the external features cropped. In conclusion, the EvoFIT system is clearly being deployed frequently, with appreciable impact, in the fight against crime.|
