Recovery of Latent Prints and Drug Residues from a Problem Porous Surface

CODEN: JFSCAS

Abstract

A protocol to maximize the probability of recovery of both drug residues and latent prints has been previously reported. A particular type of substrate (paper) has been encountered which traps drug residues in the paper matrix, thereby preventing recovery by the methods previously reported. In the case in which the existing protocol fails to recover drug residues, an additional technique is described which has allowed recovery of confirmatory amounts of the drug. The technique consists of sonication of the substrate in methanol after latent print processing.
