Finger Print Informaiton
Transcript of Finger Print Informaiton
Forensics scientists have used fingerprints in criminal investigations as a means of identification for many years. Fingerprints help scientist find the DNA of somebody so that way police/scientist would know who the fingerprints belong to. Fingerprint identification is one of the most important criminal investigation tools due to two aspects of the fingerprints: their persistence and their uniqueness.
The Case Of The Statton Brothers.
Thomas Farrow, and his wife, Ann, managed a paint shop in South London. On March 27, 1905, Mr. Farrow had been found dead on the floor of his paint shop. Upstairs, where the couple kept a small room for themselves, his wife lay, covered in blood, and barely alive. Just a few days later, Ann died. The discovery of two masks at the scene of the crime suggested the presence of more than one intruder. They found a clear print on a tray that did not match either victim. With the description given by milkman Henry Jennings, two brothers known for burglary, Albert and Alfred Stratton were held custody. Both were taken to the Tower Bridge police station, where Detective Inspector Charles Collins, a founding member of Scotland Yard's Fingerprint Branch in 1901, rolled their fingers on the inkpad. The fingerprint on the tray matched Albert's right thumb to perfection. Thus, both brothers were charged with murder.
A fingerprint in its narrow sense is an impression left by the friction ridges of a human finger. In a wider use of the term, fingerprints are the traces of an impression from the friction ridges of any part of a human or other primate hand.
Types Of Fingerprints.
There are three types of fingerprints which are patent, plastic and latent fingerprints. PATENT PRINTS - are visible prints that occur when a foreign substance on the skin of a finger comes in contact with the smooth surface of another object. PLASTIC PRINTS - are visible, impressed prints that occur when a finger touches a soft, malleable surface resulting in an indentation. LATENT PRINTS - are fingerprint impressions secreted in a surface or an object and are usually invisible to the naked eye. These prints are the result of perspiration which is derived from sweat pores found in the ridges of fingers.
