Porous Surface Processing – Optimizing and Maximizing Operational Efficiency (2 hours)
Porous fingerprint evidence received into the laboratory is typically treated with reagents specific to the constituents of the latent fingermark residue (amino acids). These chemicals, Ninhydrin, 1,2-Indanedione and 1,8-Diazafluoren-9-one, for example, produce both visible (ninhydrin) and invisible (1,2-IND and DFO) reaction products that all require time-consuming imaging considerations, to obtain usable results. Fluorescence imaging, in particular, is oftentimes extremely time consuming, given the initial necessity to screen evidence for friction ridge detail, prior to marking up and final documentable photography.
This workshop will seek to help attendees understand the most effective techniques that will facilitate optimization of results and efficient evidence workflow. Light theory will be reviewed to illustrate the interactions between illumination and viewing wavelengths in order to effectively photograph these differing chemical treatments. Attendees will study and utilize ‘conventional’ imaging methods for porous evidence types, before being introduced to a novel process that will undoubtedly increase operational efficiencies and excellence for these often‑encountered, volume pieces of evidence.
Instructor:
Jason Cole is a Technical Sales Specialist for Foster + Freeman. Jason began his Law Enforcement career as a police officer for the Sandy City (Utah) Police Department. Later he was reassigned to the Investigations Division as the detective over juvenile crime and domestic violence crime. He also began receiving training in crime scene investigation and began to process major crime scenes for the department. In 2001 Jason left the Sandy City Police Department and began working as a Forensic Investigator for the West Valley City (Utah) Police Department. In 2007 he was promoted to be the Forensic Director of the West Valley City Police Department Forensic Services Unit. In 2010 Jason left the West Valley City Police Department and accepted a position as a Latent Print Examiner with the Henderson (Nevada) Police Department. Jason served on the Board of Directors for the Utah Division of the IAI for over 10 years, including serving as President. He was awarded the Utah Division of IAI Outstanding Achievement Award in 2005. Jason has served on the Board of Directors for the Nevada State Division of the IAI since 2010, including 6 years as President. Jason works part-time as a Latent Print Examiner for the Loudoun County Sheriff’s Office and serves on the Board of Directors for the International Association for Identification. He is a member of DMORT region IX.
