Hundt said evidence as simple as a single clothing fiber, a blood drop or a shoe print could help solve a crime if it's processed properly. Hundt said he was involved recently in a check forgery case in which he was able to lift a fingerprint off a check that matched the suspect's fingerprints. There's always something to be found. It's just a matter of finding it. That's what most people don't realize.
People leave behind something anywhere they go.
Hundt said every officer can dust for fingerprints, and that may be sufficient in many crimes. One of the advanced techniques Hundt learned is to use glue vapors to get invisible fingerprints. He can also spray a substance at a crime scene that, when exposed to ultraviolet light, will alert him to blood, semen and saliva. He also learned to use plaster to preserve shoe prints and tire track impressions left behind by criminals. The Sheriff's Department turned a military surplus vehicle into a crime scene van, so the county's evidence technicians also have their own vehicle.
