Imagery Analysis - Facial and body comparison

The Brief

An unknown male, one of a group involved in a fight outside a night club in the early hours of the morning, was arrested by the Police. EUROFINS FORENSIC SERVICES were asked to examine images captured from the venue's external CCTV camera and additional Town Centre CCTV footage of the incident and conduct a Facial Comparison to ascertain whether the offender and suspect were the same person.

The Findings

On receipt of Police Custody Suite CCTV footage it was possible to capture images with closely matching angles of view that enabled a full Facial Comparison using the three recognised methods: photogrammetry, morphology and superimposition. We concluded that there was moderate support for the contention that they were the same person.

Moreover, we noted that the suspect was wearing clothing that appeared similar in type and style to that worn by the offender, including a hoodie with a prominent patterned logo on the chest. We therefore advised that, should such an item of clothing be recovered, further analysis may add weight to the contention that they were the same person.

The imagery analysis, although only providing moderate support in the first instance, identified other potential areas of work that resulted in a significantly more robust and higher level of support that resulted in a successful conviction.
