April 23, 2012 - PSI is proud to announce that our CEO Craig Fries has been accepted as a member in The Association for Crime Scene Reconstruction (ACSR). ACSR began in 1991 with a group of professionals in Oklahoma and Texas who investigated crime scenes and performed forensic analyses and comparisons on evidence from crime scenes. These professionals saw a need for an organization that would encompass an understanding of the whole crime scene and the necessity of reconstructing that scene in order to better understand the elements of the crime and to recognize and preserve evidence.
