Next crime detection technique is called the Handwritting Analysis. Last of the crime detection techniques is the Lie Detector test.

First, friction ridges for complex patterns during fetal development and remain unchanged during a person's lifetime. Second, every fingerprint has a unique pattern of friction ridges that distinguishes it from other fingerprints.

An indepth handwritting analysis can determine a person's job qualifications. The weakeness can be someone forging a signature or looks different then what it is supposed to be.

Jeffrey Dahmer Research Paper

1989 Words | 8 Pages

Fingerprint analysis is a method of identifying individuals based on the unique patterns of ridges and valleys on their fingertips. In Dahmer's case, investigators were able to use fingerprints to identify the remains of his victims and link them to specific crime scenes. Fingerprint analysis has been used in forensic investigations for over a century and is considered to be a highly reliable method of identification. It is based on the fact that no two individuals have the same fingerprint patterns and that these patterns remain consistent throughout a person's life. In Dahmer's case, fingerprint analysis was used to identify the remains of several of his victims, including Anthony Sears and Ernest Miller.

Summary Of Why Confessions Trump Innocence

608 Words | 3 Pages

Unfortunately, police and interrogators can twist the whole case around and convict an innocent person and may never even find the actual person who committed the crime. DNA testing is a powerful way to see who committed the crime. However, fingerprints are never the same, even for the same person, and like the example in the article told, there could be a twisting of the story. They might say oh the blood does not match you five, there must have been a sixth person and you five did not bleed on the victim. Even DNA testing can make innocent people commit to being guilty.

Richard Ramirez Analysis

1776 Words | 8 Pages

The Richard Ramirez "Night Stalker" case was one of the first major cases to use automated fingerprinting technology (Frese, 2011). Today, the fingerprinting database gives various probable identifications, then a trained fingerprint expert must compare the prints to find a likely identification. Considering that Ramirez's prints were found on the mirror of a stolen vehicle we can conclude that his fingerprints were two-dimensional, therefore the prints are termed as latent or residue prints. The authorities at the crime scene power-dusted his prints considering that is the best physical method for collecting fingerprints.

The Pros And Cons Of Fingerprinting

1172 Words | 5 Pages

Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).
