Benefits of Fingerprints in Solving Crimes

Fingerprints are something people take time to contemplate about on a daily basis. In fact, the average person only thinks of fingerprints when trying to wipe off fingerprints from mirrors or furniture.

But for a few people, fingerprints are an essential portion of their job life. Law enforcement officers and forensic specialists spend hours thinking about fingerprints, trying to find, collect, document and compare those unique identifiers that could link a particular person to a particular offense. These people understand that a fundamental human feature is one of the most effective instruments in crime solution.

Each Individual is born with their unique set of fingerprints. No two fingerprints are alike; not on identical twins or even on a individual’s own hand. The formation of these unique whorls and lines that constitute an individual’s fingerprints happen at the fetal period and stay the same during one’s lifetime. This creates a unique mark which can single out an individual linked to a particular crime, especially when a person already has their fingerprints in the records of the police or other government institutions.

Fingerprints comprise a set of swirling lines. How these lines shape and design themselves is exactly what makes every fingerprint unique. Regardless of the unbelievable number of fingerprints, there are only seven distinct kinds of lines which make up fingerprints. These lines can begin, stop or divide at any location within the print. The shapes, lengths, angles, heights, and widths create billions and billions of unique prints.

Using their unique attributes, it becomes simple to see precisely how fingerprints can help solve crimes. Leaving a fingerprint is similar to leaving a calling card at the crime scene. There are different ways fingerprints are left behind by poor crooks. The most common way is by oil transfer from the finger onto an object such as a doorframe or table. Amino acids in the finger may even leave a discernable mark. Detection of fingerprints can also be detected as an impressing on a soft substance. Additionally, they can be created by something on the finger like paint or blood.

Uncovering fingerprints to help resolve a crime could be carried out in a couple of ways. Adhering powders onto new fingerprints will make the powder adhere to the grease making the fingerprint visible. Another technique is using several drops of cyano-acrylate or even superglue. When these drops are heated, they vaporize, and their smoke attaches to the fingerprint leaving a white print. Specialised crime scene laboratory equipment can also find fingerprints.

Fingerprints may be stored for more investigation in many of ways such as: capturing a photo of the printing, storing it on a tape or rubber lifter, maintaining the original ground the printing was on and copying it utilizing digital technologies.

Ideally, from a crime-solving standpoint, hopefully, the interconnected nature of the society will gradually result in having all of the fingerprint databases connected for simple cross-reference.
