The Missouri Division of the IAI holds an educational conference each year. The conference covers multiple disciplines within the IAI including: latent prints, crime scene photography and scene investigation practices. Previous speakers at the conference include: David “Ski” Witzke, Matt Schwarz, Lt. Gallup from the Joplin Police Department, and Kim Hardin from the Missouri State Highway Patrol Crime Lab.
Due to the pandemic, the Educational conference will not be help in a physical location. Instead we will have free webinars. They will still be held on October 22nd and 23rd.
Redefining Possibilities: The Development of Latent Fingermarks from Cartridge casings and Cleaned Metals Using A Novel Vapor Phase Technique.
This presentation will begin by providing attendees with a background to a new novel chemical fuming process that has been shown to offer significant advantages over traditional latent fingermark enhancement processes across a range of metallic substrates (copper, brass, stainless steel, etc.). Described by the UK Ministry of Defense as ‘revolutionary’ and ‘ground-breaking’, the unique ability of this process to recover fingerprint ridge patterns when none of the latent fingermark residue actually remains on the substrate (i.e. the surface has been wiped clean, washed, submerged in water, heated, or a combination of these) will be explored and practical examples illustrated and discussed.
The webinar will take place on October 22nd at 10 a.m. To register, click here.
Detect More Evidence: Extend Your Search Beyond the Visible: Various types of evidence are often overlooked at a crime scene because they are not visible to the naked eye. When using an alternate light source with the proper corresponding filter, it is still possible to miss items of evidence due to background interference or improper angle of illumination. The purpose of this workshop will be to introduce attendees to various methods utilized in detecting evidence beyond the visible range. An introduction to light theory and techniques utilizing wavelengths of light beyond the visible range on notoriously difficult surfaces will be discussed. This will include ultraviolet and infrared examination to detect the presence of biological fluids, gunshot residue, and fingerprints on difficult backgrounds. Novel oblique lighting techniques will be explored to detect evidence on raised surfaces and footwear impressions. Bandpass filtering techniques will also be explored to aid in the detection of evidence at crime scenes. Attendees will be introduced to non-visible lighting techniques and digital capture of fingerprints developed using various treatment methods including cyanoacrylate fuming and IR fluorescent fingerprint powders.
