Case Studies

EvoFIT produces composites with a suspect identification rate of approximately 60 percent, compared to only 5 per cent from ‘feature’ systems.

There have been a number of evaluations of the effectiveness of EvoFIT in police field trials. These have involved use of the EvoFIT system by trained police practitioners for an extended period of time, and assessment of the number of arrests based on the composite image, utility as an investigative tool and subsequent conviction. As the EvoFIT system has been improved (through carefully designed experiments to mirror the real world situation as far as possible), effectiveness has increased progressively. In the most recent evaluation, the suspect identification rate is approximately 60 percent, following construction of a criminal face image by witnesses and victims.

Since 2001, EvoFIT has been used in the following constabularies: Avon and Somerset, Bedfordshire, Cambridgeshire, Cumbria, Derbyshire, Devon and Cornwall, Dyfed Powys, London (The Met), Greater Manchester (GMP), Hertfordshire, Humberside, Kent, Lancashire, North Wales, Scotland (Police Scotland), Northamptonshire, Northern Ireland (PSNI) and Staffordshire.  Our overseas customers include Boston, Israel, La Garda (ROI) and Romania. 

Here are some of the cases where EvoFIT has been indispensable in solving the crime.

Rape

Asim Javed (right) was recently convicted of the rape of two students in the south Manchester area. The EvoFIT (left) was constructed seven days after the attack by the latest victim. Javed was identified (by many people) from the EvoFIT and was subsequently given a custodial sentence of eight years.

Aggravated robbery

The above person was found guilty of robbery. The offender (right) threatened victims with a knife and then punched them in the face. The EvoFIT image (left) provided the identification which solved the case.

Theft

These two EvoFIT composites were constructed by separate witnesses, working independently of each other, to locate the perpetrator of four bicycle thefts. On the far right is a photograph of the person believed to be responsible for committing these crimes.

Training

Training is a vital component of successful implementation of EvoFIT; we run comprehensive training courses with assessment, or shorter application-training courses, to fit with our licence agreement.

EvoFIT courses are regularly available as a standard option for new users either off-site or our main training facility in Preston…

Research

Successful trials have demonstrated that EvoFIT outperforms current computerised composite systems.

The construction of a composite by assembling individual facial features is a common exercise in criminal investigations. Photofit, identikit, efit and other ‘feature’ types are old fashioned systems…
