Investigator
EIELSON AIR FORCE BASE, ALASKA--Investigator Christopher Stone, 354th Security Forces Squadron investigator, places a piece of evidence in a stainless steel cup, in the fuming tank Feb. 2 at the 354th SFS complex. SF investigators use a super glue-like compound combined with a heat source and a cup of warm, distilled water (for humidity) inside the fuming tank to make otherwise invisible fingerprints visible.
