Just Consecutively Manufactured Toolmarks

In episode seven of the IPTES season, Just Science interviews Robert Thompson, a Senior Forensic Science Research Manager at the National Institute for Standards and Technology (NIST). Mr. Thompson discusses his research on consecutively manufactured barrels and his recent research on “Objective Comparison of Striated Toolmarks Produced from Ten Consecutively Manufactured Cold Chisels Measured by Contact and Optical Surface Profilometry and Comparison Microscopy”. The profile’s similarity and differences were compared using two mathematical methods, cross-correlation function, and the recently developed congruent matching profile segments method.

This episode of Just Science is funded by the National Institute of Justice’s Forensic Technology Center of Excellence [Award 2016-MU-BX-K110].
