Catching more offenders with EvoFIT facial composites: Lab research and Police field trials.

  Often, the only evidence of an offender’s identity comes from the memory of an
eyewitness. For over 12 years, we have been developing software called EvoFIT to help
eyewitnesses recover their memories of offenders’ faces, to assist police investigations. EvoFIT
requires eyewitnesses to repeatedly select from arrays of faces, with ‘breeding’, to ‘evolve’ a
face. Recently, police forces have been formally evaluating EvoFIT in criminal cases. The current
paper describes four such police audits. It is reported that EvoFIT composites directly led to an
arrest in 25.4% of cases overall; the arrest rate was 38.5% for forces that used a newer, less
detailed face-recall interview. These results are similar to those found in the laboratory using
simulated procedures. Here, we also evaluate the impact of interviewing techniques and outline
further work that has improved system performance.
