Fingerprinting; Who Killed The Lamb?

Fingerprinting; Who Killed The Lamb?

Problem: Who or what killed the lamb.

Research Info: The way fingerprints are usually taken is the person searching dust the area and if there are fingerprints they show up after you wait a bit.

When looking at fingerprints and trying to match them the people look for loops, arches, ridges, and whorls a lot, then at there sub patterns (USA Today Magazine June,7 2007 page 15). Also distinctive traits like lines, scars or double loops. Fingerprints are usually used for trying to tie someone to a crime. They are also used to eliminate suspects from crimes. Fingerprints are usually the best method to use at a crime scene because DNA testing is expensive and it’s usually harder to find DNA (The Economist Magazine
April 20, 2004 page 23).

Are left they smudge and get distorted. In 1995, a proficiency test with 165 examiners one in five made one false positive match (www.truthinjustice.org/fingerprints). Even though every once in a while fingerprints are wrong mostly they are right because of there uniqueness so a lot of people still use them in crimes.
