ABSTRACT:
A portable latent fingerprint fuming apparatus for developing white-colored crystallized prints on nonporous, flat and uneven surfaces as well as objects has an air-tight housing. The housing has a sidewall, a ceiling, an aperture through the housing and an open bottom with an expansible, pliable boot or flange therearound extending downwardly and having a lowermost pliable flange adapted to air-tight sealably engage the nonporous, flat and uneven surfaces. A receptacle may be provided for holding super glue or cyanoacrylate within the housing. A vacuum pump is in flow communication with the aperture, suitably by tubing, for vacuuming air out of the housing sealably engaged with the nonporous surface, for creating negative pressure within the housing and about the latent fingerprint, and for vaporizing the cyanoacrylate for deposition upon, and crystallization of, the ridges of the latent fingerprint.
