Welcome back here to part 2 of the 200+ page views post! We're continuing the forensic science tips here on the Catch the Thief book. Here's some more tips:
Fingerprint tips:
Fingerprints are often used for identification. Each fingerprint is unique, so it can only belong to one person. Fingerprints also follow one of three basic patterns: loops, whorls or arches. About 60% of people have loop-type fingerprints, 35% have whorls and 5% have arches. However, a person can have more than one type of fingerprint. (eg: a person may have a loop on one thumb and a whorl on the other).

Physical Evidence tips:
Fibers collected at a crime scene are usually examined with a microscope. To be useful as evidence, the fiber should be examined to determine what is it made of, what sort of dye it has in it, and where it might have come from. In the end, it is important to have a sample of a known fiber for comparison.

When examining footprints, take into account the recent weather. Wet weather usually means good prints, but they will be deeper than normal prints. Dry weather means shallow prints - or even no prints. If the prints are on something hard, like concrete, obviously foot impressions will not be left behind. If possible, try to determine the distinct tread of a shoe.

That's the end and I hope you will enjoy it, and read part 3 soon!
