Crime Scene Technology at Keiser University’s Jacksonville Campus had guest speaker, Allen Miller (Forensics Source Senior Representative, Jacksonville, and former FDLE Forensic Lab Examiner) come out and speak with the students about his experience and the proper use of Alternative Light Sources (ALS). Mr. Miller explained to the students the use of an ALS to assist with the search of evidence at a crime scene.  The ALS utilizes different wavelengths of light to highlight evidence in contrast to the background it is found upon.  The light is viewed by the user through barrier filters, which block certain wavelengths of light while allowing a specific wavelength to be visible to the user.  This visible wavelength reacts with the item of evidence  (body fluid, bone, fibers) allowing the user to be able to isolate and identify through luminescence.
