Overview

•A multiple-lab study on CFS has been carried out for the first time.•Each participant employed her/his particular methodology and technological means.•Provide important insights to better understand the most convenient characteristics. As part of the scientific tasks coordinated throughout The ‘New Methodologies and Protocols of Forensic Identification by Craniofacial Superimposition (MEPROCS)’ project, the current study aims to analyse the performance of a diverse set of CFS methodologies and the corresponding technical approaches when dealing with a common dataset of real-world cases. Thus, a multiple-lab study on craniofacial superimposition has been carried out for the first time. In particular, 26 participants from 17 different institutions in 13 countries were asked to deal with 14 identification scenarios, some of them involving the comparison of multiple candidates and unknown skulls. In total, 60 craniofacial superimposition problems divided in two set of females and males. Each participant follow her/his own methodology and employed her/his particular technological means. For each single case they were asked to report the final identification decision (either positive or negative) along with the rationale supporting the decision and at least one image illustrating the overlay/superimposition outcome. This study is expected to provide important insights to better understand the most convenient characteristics of every method included in this study.
