Create a Profile Experiment

In this experiment, we were tasked with identifying and organizing the clues presented to us at a pretend crime scene. The clues included a set of four fingerprints, a ripped-up note, a red smear of unknown substance, and two hairs.

#1 - Plain Whorl, #2 - Ulnar Loop, #3 - Ulnar Loop, #4 - Ulnar Loop

 

Caucasian hair, possibly color-treated?

Note, reads "You will never find her"

Very dark hair - Asian or color treated?

Red stain - blood, lipstick?

After analyzing the data given to us, we made the following notations:

• The fingerprints turned out to be two tented arches and two plain whorls.
• The two hairs were
• one color-treated caucasian hair
• one very dark black hair (Asian? African-American?)
• The note, when put together, read "You will never find her".
• We were unable to further investigate the red stain, and it is unsure whether it is a bloodstain or lipstick smear. Judging from the shade of red, we are leaning towards lipstick, but without further evidence we cannot make any assumptions.

1. What do we know? What do we need to further analyze? What do we not know?
1. We know for sure the types of fingerprints present in Clue #1 - plain whorl and three ulnar loops. Another thing we know is that after you piece it together, the note reads "You will never find her". The last thing we know for sure is that Clue #2 is a color-treated Caucasian hair.
2. Things we need to further analyze are the hair from Clue #4 and the hair from Clue #2. We could take these to lab to see if there are still any traces of tissue left on the hair, and if not, we could use a comparison microscope to match it up to discover what they are.
3. Things we do not know much about is the red stain. It could be a lot of things: the most obvious being blood, and others being lipstick or even red juice. 
2. Create a Profile
1. Based on the clues presented to us, we think that a woman with color-treated hair was at her home when a man with dark hair (either Asian or color-treated as well) broke into her home, leaving his fingerprints on the door. There was a struggle as the man tried to abduct her, in which the woman was hurt, which left blood somewhere in her home. Hair was pulled from both of their heads as they struggled. After successfully restraining the woman, the man wrote a quick note, reading "You will never find her". 
3. How could this case be solved?
1. First and foremost, forensic scientists could try and match the fingerprints using their system. Another way scientists could solve this case would be for them to examine the hairs left behind for tissue, and then try to analyze the possible blood to type it, if it is indeed blood.
