Annotation: This article discusses the need to pretreat surfaces coated with gasoline for subsequent successful latent fingerprint processing.
Abstract: Although methods exist for the processing of oil or grease prints on items of evidence, it has proven problematic and most often ill-fated to develop fingerprints on items of evidence that have been completely coated with petroleum-based products. Attempts to safely remove the contaminant, while preserving and developing the underlying fingerprints, have had little or no success. Experimentation demonstrated that heptane can effectively remove a petroleum product, such as gasoline, from nonporous surfaces, thus preparing the surface for subsequent successful latent print processing with currently accepted methods for the development of oil and grease prints.
