marks on glass and metal exposed to water is CA. The exper- iment established and confirmed that finger marks on glass ve and metal surfaces can be developed even after having been ts, exposed to water for 168 h. When checking the specialist literature 2.3.8-16 of detecting der latent fingerprints left on wet surfaces we found a few arti- to cles with good results. Authors used several fingerprint tech- as, niques, e.g., Oil Red O, SPR, ferromagnetic powder, cyanoacrylate fuming and black powder. Wood et al.16 ut found that Oil Red O was the best development technique nt on paper while SPR reagent worked best on plastic. They n- examined the persistence of latent fingerprints in various d types of water and accelerant where fingerprints were placed ts on paper and plastic surfaces. The surfaces were exposed to er the influence of liquids during different time intervals. Re- sults have shown that latent fingerprints can last for a pro- 4 longed time in liquids This study was done to investigate fingerprints on wet transparent foil. The purpose of this study is to determine the suitable method for recovering finger marks on transpar- ent foil recovered from stagnant water, to be used at crime scenes when it is thought that the perpetrator may have han- dled or touched those objects and thrown them into water. sting by Elsevier B.V.
