Forensics – the use of scientific testing to investigate crimes.
Digital Cameras – Digital cameras leave a “fingerprint” buried within in the pixels.
Each digital picture is overlaid with a unique pattern (fingerprint), or noise. These patterns can be traced back to the camera that took the photo.
Forensic dentistry – Sure, we all know forensic dentistry is used to identify John Doe victims, right?
But did you know that dental forensics is also used in dental malpractice and dental personal injury suits?
Wet surface fingerprinting – Since oil (from human skin) and water don’t mix, it’s possible to lift usable fingerprints from a wet surface, such as a vehicle that’s been sitting out during a rain shower.
However, water spots can form after the surface dries, which can affect the quality of the prints.
Virtual autopsy – Multidetector computed tomography (MDCT) scanners have been used to examine both soft tissue and bone. Since radiation is not an issue for the dead, the machines can be utilized at the highest, most intrusive settings.
Pathologists use the scanners to study muscular-skeletal system, cranium, facial bones, spine, central nervous system, cardiovascular system, respiratory system, airway, pelvic organs, upper GI tract, foreignobjects, and even the victim’s personal effects without ever opening the body bag.
Digitally enhancing photographs – Iodine fuming and Adobe Photoshop are a great team!

Hairspray – When making impression casts in sandy or loose soil, spray the area first with hairspray to hold it in place.
