Latent prints are chance or accidental impressions left by friction ridge skin on a surface, regardless of whether it is visible or invisible at the time of deposition Recognition of evidence that may contain fingerprints and the processes that can develop these latents is crucial in preventing valuable evidence from being left undetected. It has been my experience that basic police training does not cover this subject adequately and other first responders may not receive any training at all. To process latent prints examiners use various techniques including electronic, chemical, cyanoacrylate and physical method. Latent Print Processing Guide offers a broad understanding of latent print detection, development and recovery including insights on some state of the art technologies. Includes history of latent print identification and some of the pioneers and their contributions. Defines the differences between chemical and physical processes, explains process sequence protocols and recovery methods for different types of evidence Chapters include: process selection, application and recovery, special considerations for specific materials, protocol sequence and process formulas including required materials, application method, expected results, safety measures and references. The text is written so that non-crime scene or non-crime laboratory personnel can gain valuable information from it.

Latent prints are chance or accidental impressions left by friction-ridge skin on a surface, regardless of whether they are visible or invisible at the time of deposition. Recognition of evidence that may contain fingerprints and the processes that can develop these latent prints is crucial in preventing valuable evidence from being left undetected. Latent Print Processing Guide goes beyond the basic police training, covering latent prints in detail and providing first responders with adequate training and guidelines. To process latent prints, examiners use various techniques including electronic, chemical, cyanoacrylate, and physical methods.

The identification of latent print evidence is often key in solving a crime. A latent print results from the reproduction of friction ridges found on parts of the fingers, hands, and feet. These prints consist of a combination of different chemicals that originate from natural secretions, blood, and contaminants. Natural secretions mainly derive from the eccrine and sebaceous glands and contain known chemical components. Eccrine gland secretions from the fingers, hands, and feet are both organic and inorganic, but only organic materials are secreted from the sebaceous glands. Other contaminants found in prints result from contact with different materials in the environment. Latent prints can be found on all types of surfaces. In general, surfaces can be characterized as porous, nonporous, or semiporous. Understanding these characteristics will aid in processing an item for latent prints. The beginning of this manual is a list of processes and procedures for different surface types. Also included are processing sequences that specifically involve prints that are left in blood. Following these lists are details for each process that is currently implemented in the Latent Print Unit (LPU) of the Federal Bureau of Investigation (FBI) Laboratory.

FBI Handbook of Crime Scene Forensics is the official procedural guide for law enforcement agencies, attorneys, and tribunals submitting evidence to the FBI. This handbook outlines the proper methods for investigating crime scenes, examining evidence (bullets, computers, hairs, inks, lubricants, ropes, shoeprints, tire treads, weapons of mass destruction, and more), packing and shipping evidence to the FBI, and observing safety protocol at hazardous crime scenes. At once a guide for professional forensics experts and an introduction for laymen, FBI Handbook of Crime Scene Forensics makes perfect reading for fans of Cold Case, Silent Witness, and the Law & Order and CSI franchises, and anyone with an interest in investigative police work and the criminal justice system.

Fingerprint identification is the most efficient, rapid, and cost-effective forensic identification modality. Postmortem Fingerprinting and Unidentified Human Remains is a consolidated and thorough guide to the recovery, identification, and management of unidentified postmortem fingerprint records - topics from postmortem fingerprint processing to database submission and case management are discussed. Additionally, a postmortem processing workflow is described, which delineates various basic and advanced fingerprint recovery techniques used to acquire examination-quality records. Furthermore, Postmortem Fingerprinting and Unidentified Human Remains discusses the complexity of antemortem fingerprint databases and how to access each database for humanitarian purposes, bringing a modern value perspective to the topic.

Latent fingerprints are made visible from the surface of objects using a variety of methods including physical and chemical processing, adapted illumination sources, and photographs. Unfortunately, the prints collected directly from a crime scene or from physical evidence may be incomplete or damaged, to the point of being considered unsuitable to send directly to latent fingerprint examiners for identification or to Automated Fingerprint Identification System (AFIS) for recognition. As a result, most latent fingerprint images must be preprocessed to enhance fingerprint information, at the same time suppressing interference arising from noise and otherwise unwanted image features. This preprocessing phase occurs after the latent print is collected from the crime scene and digitalized by a scanner or camera, and before the image analysis and process phase such as minutiae markup or latent print identification. The preprocessing results can be extraordinary, transforming raw images with little or no value into ones suitable for evidentiary analysis. Despite the importance of this step, there exist few databases designed especially for the scientific study of latent fingerprint image preprocessing, and even fewer standards to guide this workflow. To address this research gap, we conducted a study in which a group of trained Latent Print Examiners provided Extended Feature Set (EFS) markups of a series of latent images. This report provides a brief introduction into fingerprint preprocessing, discussion regarding the experimental design, structure, and contents of the latent fingerprint image database, and details of proposed preprocessing efficacy metrics. Additionally, we present preliminary analysis of these metrics when applied to images in our database. Previously Guan et al. [6] presented the performance metrics and analysis of the metrics as applied to a union minutiae set. In this report, we comprehensively document the contents of the records database including the latent images, the EFS markup files, metadata, markup logs, and region of interest masks. Additionally, we present the results of the performance metrics as applied to the intersection minutiae set of EFS markup data.

Technology has changed considerably since the second edition of the guide was printed. While records continue to be a critical component of the operation of a law enforcement agency, the changes in technology are proving to be a welcome addition to the tools a records manager may have to keep pace with the increasing demands for records storage and retrieval. The manual will provide a glimpse of new technologies and systems that are available to law enforcement today. Since the last edition was published, there have been significant changes in the legislation, several of which require reporting of specific crimes to the California Department of Justice. Those legislative changes and case law decisions affecting records managers have been included in this edition. We have expanded the scope of our records manual and include information on new justice data systems which are available to all California law enforcement agencies.
