Create a Profile

In this experiment we were given a set of clues. There were five clues given and from those clues we had to create profile. Forensic scientists do this on daily basis. There were four fingerprints we had to analyze. We analyzed a string of hair which we concluded to be a Caucasian women hair.  We also analyze a hair that we found to be a cat hair. Then we found a red gelatin substance and a note that said “you will never find her”. From those clues we conclude that a women was kidnapped who owned a cat.

Crime Scene

Crime scene was in front of garden no body just evidence. There were eleven clues and we had to analyze those clues.  

Clue 1: a dirty heel

Clue 2: A: “someone help me please”

B: “You’ll never find her”

Clue 3: A: fingerprint- whorl

B: fingerprint- ulnar loop

Clue 4: a thick hoop earring- Tyese Jefferson

Clue 5: fabric- Nylon- green

Clue 6: Iodine- Tyese Jefferson

Clue 7: footprint- male- vans

Clue 8: A+ blood

Clue 9: multiple color hairs (brown, black, blonde) - dog hair

Clue 10: fingerprint on glass- Smokey Johnson

From those clue I have came up with a scenario of what had happen.  Tyese owns a dog and who is a counselor. Tyese was counseling a man who was physically abusive to women. The man was Smokey Johnson who had to have a restraining order put on him because he was that crazy. Smokey Johnson began to fall in love with Tyese. One night after her counseling secession with Smokey Johnson, Smokey had said some bizarre things to her which mad her fear her safety.  She wrote a note that said, “Someone help me please”.  Later on that night when she was the most vulnerable Smokey Johnson came for her while she was on her way in her house. He threw her on the ground which caused her heel to come off.  During the struggle he ripped her earring out of her ear causing her to bleed. He then grabbed her medicine from her bag filled her with enough iodine to make her drowsy. He then kidnapped her, leaving fibers at the crime scene. Also he left a note that said "you'll never find her".

Drug Activty

In this activity there was six drug samples of cocaine, methamphetamine, and LSD. We test substances to see if they had contained any of the drugs by using pH strips and identifying their reagents.

Footprint Analysis

In this activity we analyzed footprints. We first  had to find out temperature, humidity level, when the last time it rained, and the where the wind was blowing. Then we stepped into a pan of dirt, and had to measure the length of the print as well as the depth. Then we had to figure out the direction of the footprint and also look at the design on the bottom of the shoe.

Lip Activity

In this activity we were able to analyze our lips by applying lipstick to our lips and kissing an index card. As you can see my lips are curvy and full and also have have a lot of creases.

Witness Experiment

As a witness to a crime, your cooperation is essential to make the criminal justice system work. Memory is a vital part of being a witness it requires you think, remember what the culprit look like. In this experiment that was conducted me and a few fellow classmates memories were put to test, we were in groups and each group member had to find a similar size face.We each  had to memorize the face we chose. Then we had to cut out the eyes, nose, mouth, and the hair. Then we had to mix the pieces up with the other group members pieces. after about five minutes we then had to piece back the face we chose originally. What I have learned from this experiment that being a witness is somewhat hard because sometimes you tend to forget things and it makes it hard to piece together what you saw.
