Lifting fingermarks is never easy. Based on the surface on which the fingermark rests, the examiner decides whether lifting would be needed or not. This is also true for papered documents. Normally, latent fingerprints are not required to lift because the prints are soaked in and no longer on the paper surface. Thus, they are […]

When analyzing questioned documents with fingerprints, it is imperative to know what to do and what are the real limitations. Some limitations, however, are myths, while others are simply misconceptions. Fortunately, I gathered some data about the common misconception and myths related to fingerprints on papered documents. Myth 1: Wiping Removes Soaked Fingerprint From Paper

Amputated, scarred, and missing from birth fingers are uncommon, but still need to be classified using the Henry classification system by the FBI (or any other classification system). Moreover, classifying them is a tedious task. There are a set of rules that are needed to be followed by a fingerprint examiner. So, if you’re here

The second sub secondary division is a rarely used extension for classifying fingerprints in the Henry system. This classification is generally used when a fingerprint class becomes too large for an effective small searching group. So, the very first aim of this extension is to simplify and speed up the identification process. Later, in this

Extension to Henry’s fingerprint system is quite a viable way to come up with smaller groups for comparisons. Fingerprint classification extensions are used by various federal agencies to downsize the larger groups making classification systems more efficient and less time-consuming. To meet the efficiency of searching prints in larger groups databases, many federal agencies come

Final classification is a special subdivision of the Henry fingerprint system where the ridge counting of either little finger is used to obtain the final classification number. In this classification, if the values are from the right little finger, it sets in the numerator. For the left little finger, values are placed below the henry

Sub Secondary Classification is a subdivision in the Henry fingerprint system whose values are represented by symbols based on the ridge tracing and counting values of whorls and loops pattern. Index, middle, and ring finger values are used to classify this division. In this short post, you’re going to get to know what are the

Major classification is a subdivision of the Henry Fingerprint system (FBI modified) whose values are set in between the key division and primary division. Their values are based on the pattern present on the thumbs (number 1 and number 6 fingers). In this article, you’re going to know in-depth information on how to calculate the
