Latent prints can be defined as the pretense of individual’s ridged skin. They are generally known as friction ridges or fingerprints. These impressions are regularly imperceptible to the exposed eye despite the fact that they are surrounding us and each one of us accidently leaves them everywhere. At the point when an investigator is dealing with a crime, other than taking a gander at the physical proof, one of the main things they do is check for fingerprints. This is an exceptionally sensitive process on the grounds that relying upon the surface a latent print can without much of a stretch be wrecked (Holder, 2011).
The two distinct surfaces that will be prepared amid this investigation is porous and non-porous. If to talk about porous surface, it permits latent prints to halfway assimilate into the surface and it is less complicated to concentrate fingerprints from. Porous things that were examined around that house were an envelope, a piece of paper, and a kitchen cutting board. Non-porous surface can be defined as a surface that was not painted. For example, it might be all kinds of plastic materials, things made of glass or metal. These surfaces are considerably more delicate on the grounds that the latent print may simply be lying at first glance (Bodziak, 2000). The things that were examined around the house on this kind of surface was a window lift, a wine glass, and a wooden door handle.
This examination took place in the kitchen and lounge area. I concentrated on these two territories essentially on the grounds that they are the main spots you see when you stroll into my condo and where I spend most of my time. Since me and my friends spend most of our time in these parts of the house and they contain both, porous and non-porous surfaces, I am hoping to discover numerous fingerprints from various items.
I have used some supplies to clean and gather the prints from the 6 before mentioned items. This list includes:
Mortar grinding machine
Corn starch
Chalk
Large makeup brush
Clear wide scotch tape
Piece of dark paper
At the beginning, I broke a piece of chalk into little pieces and turned it into powder using the mortar grinding machine. In order to make a fingerprint powder I mixed the chock powder with the corn starch.
I decided to start with a wine glass. Trail 1: I utilized the makeup brush to put some powder onto the wine glass. After I covered the prints, it was necessary to remove the overabundance powder, so I just blew on the wine glass . I utilized the tape to lift the print. Then I put the tape on the paper. The outcome: smudge fingerprints (Fail). Trail 2: Using the makeup brush I sprinkled the powder on another arrangement of prints on the table this time guaranteeing the brush did not touch the prints. Taking after an indistinguishable methods from above resulted in a much cleaner prints. In total, I clearly discovered 3 unique prints.
Subsequent to examining the wine glass, I examined the envelope and the piece of paper. Without any idea about what parts of the envelope I touched, I tidied the mailing mark, near the envelope’s edge, and the seal. As a result, I found out that the envelope contained a great deal of halfway and smudged fingerprints. I could lift some clear prints which I precluded as being mines since they matched a couple prints from the wine glass and were less demanding to see, most probably they were fresh. I chose to examine the back of the paper rather than the front since while writing a letter I smudged my fingerprints and the main thing I would discover was a print of my palm finger. I managed to find several fingerprint on the back of the piece of paper there despite the fact that they were not perceptible.
Next was the window lift. At that time, it was opened and that is why I made a decision to close it and saw there were a couple of unmistakable prints that were marginally cleaned over. I chose to utilize the tape and check whether I could lift the prints without utilizing the powder. The outcome: an incomplete print however no clear fingerprints. Then I examined the new prints that I had recently left on the window glass and managed to lift better latent prints.
Then I moved to the items from the kitchen; the wooden door handle and kitchen cutting board. One side of the door handle was wet since I opened the door having wet hands. In the meantime, the other side of the handle was dry. Therefore, it took some time before the handle became totally dry. Grasping the edge I sprinkled powder on the handle. There were a couple of observable prints before tidying yet once I attempted to lift the prints they were altogether smudged and were covering each other. The cutting board was the most hard to examine. I did not manage to discover any prints because of all the blade marks and the surface of the cutting board.
