Fingerprint Analysis On paper it is supposed to be Alex Garcia
There are three types of finger prints, whirl, loop, and arch. Loop is... well a loop. Whirl is a swirl-like print. Arch is when a side goes up and then goes back down.
When you want to take a latent print, you take a glass slide, get some oil from your face or somewhere, then take your thumb and lightly press it on the glass slide. After you do that you put a piece of tape ontop of it nicely, then brush it. After that remove the tape and there you have it.
I found that the print belonged to Alex Garcia. As you can see, this fingerprint is a loop, and the only person with a loop fingerprint on the list is Alex Garcia.

Hair and Fiber Analysis
I determined that the hair at the scene of the crime belonged to Anna Garcia herself. When examining carefully under a microscope they have the same color, and also if you look closely the pattern of it is the same.

Whose DNA is it? DNA profiling is the process of testing DNA by cutting it into strips and letting it flow through gel electrophroesis. What happens first is the DNA gets cut by restriction enzymes, then placed in the walls of a solution. Then when electricity is given the DNA will flow towards the gel. That is because opposites attract. |
