The human eyes are only capable of seeing approximately 3% of the light spectrum and, as such, are incapable of locating and collecting certain forensic items that are present at scenes. The proper deployment of alternative, light source technology greatly aids in searching for, locating and collecting items of forensic interest. This course will assist law enforcement in utilizing ALS technologies via ultraviolet, blue and infrared systems to search for and record these elusive items, thereby increasing their effectiveness and the amount and types of evidence located. Further, this course will assist individuals in formulating their working experience for future use in documenting items, such as subcutaneous bruises, bite marks, blood, on patterned and dark colored surfaces and gunshot residue on dark cloth.
