Because some techniques are often intricately related and continuously changing, it is imperative that those involved in laboratory and crime scene processing be well trained and well practiced. This chapter describes the nature of latent print residue and the most commonly used fingerprint development techniques.

Insights from a Forensic Expert—all for far less than what you’d spend on a single latent print processing course.

105–179) for a recent review that includes many fingerprint development techniques. The following general procedures are appropriate during a systematic search for latent finger-print evidence: • Visual inspection with a bright light, forensic light source, or laser • Sequential latent print processing

The results of all visual examinations and processing techniques completed by the examiners and technicians are documented and preserved through digital photography. The latent print section has two capturing stations (DCS-4) available for use. Each of these systems is composed of a high resolution digital camera,

of Fingerprint Evidence •Processing techniques vary depending on the type of surface the print was left on, as well as the residue of the latent print, including perspiration, blood, oil or grease, and dust. •The condition of the surface, characteristics including dryness, wetness, dirtiness, and tackiness or stickiness, also contributes

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.

latent print processing and/or friction ridge analysis and comparison. Examinations which only include comparisons of known recordings of a person’s friction ridge detail are normally the purview of the WSP Identification Section. All requests for this type of

This report presents the Federal Bureau of Investigation’s (FBI’s) processing guide for developing latent prints. Abstract The guide begins with a list of processes and procedures for different types of surfaces, including both porous and nonporous surfaces, and includes a consideration of the specific processing sequences that are ...

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 of the Federal Bureau of Investigation Laboratory.

The FBI's latent print program ensures the quality and advancement of the latent print discipline by providing tools, training, and support for investigative, humanitarian, and intelligence programs. ...

1.3.4.1 Anatomical source is the designation of the latent print as a fingerprint, palm print, toe print or footprint 1.3.5 Anchor point 1.3.5.1 A feature present in the latent print that allows an examiner to reliably determine the anatomical location of the unknown impression. Delta, core, or the following: distal transverse crease,

The fingerprint is developed by first evaporating a thin layer of gold onto the specimen, followed by a layer of Cadmium which fills in the print and provides a contrast. Bacteria . Certain bacteria, for example “Acinetobacter Calciacatieus”, can be used to develop prints on valuable oil paintings.

3. Latent Print Processing and Preservation 3.1. Processing techniques should progress from least destructive to most destructive with consideration for the sequential targeting of friction ridge residue components and DNA preservation. 3.2. Examiners should develop examination plans and strategies in conjunction with other

There is good cause to doubt the reliability of latent print ridge analysis. In the PNAS study, for instance, researchers challenged 169 latent print analysts to examine 100 prints, then measured the accuracy of their results. In the end, 85 percent of analysts made at least one false negative, leaving an overall false negative rate of 7.5 percent.
