Crime Investgation Scene

Setting: In a resident home and the surrounding area of the home.

Victim:

Tyese Jefferson: Counselor

Suspect: Smokey Johnson: Has an restraining order against him

Evidence Found at Scene

EXH 1: Women black shoe and it is Tyese Jefferson

EXH 2: Note says" Someone please help me" belongs to Tyese Jefferson

EXH 2A: note says " You will Never find Her" written by Smokey Johnson

EXH 3: Fingerprint that is a central pocket loop belonging to Smokey Johnson

EXH 3A: Fingerprint that is a tented arch belonging to Tyese Jefferson

EXH 4:  Large golden earing that belongs to Tyese Jefferson

EXH 7: Male footprint belongs to Smokey Johnson

EXH 8: A+ blood that belongs to Tyese Jefferson

EXH 9: A hair sample that belongs to a dog

EXH 10: The print lifted was a tented arch which belongs to Smokey Johnson

We have figured out that the victim is Tyese Jefferson and we have deducted that Smokey Johnson did murder the victim. The victim placed a restraining order against Smokey Johnson which probably angered him. Smokey Johnson delivered a drink filled with poison to the victim at her job because he worked at the Food Service industry.  Through exhibit 6 he poisons her with Iodine and that becomes a great problem for person with thyroid problems and our victim has that problem. She probably started to feel the effect of the poison on her way home. When she made it home she took of her shoes off and played with her dog until she started coughing up blood. Through exhibit 9 we found that her blood on the scene and Iodine poisoning has an effect to make the victim bleed from the mouth. The dog hair was probably from her playing with her dog when she got home. She spots Smokey Johnson coming toward the house and she writes the note before she dies. As she collapse she rips her stocking which is green nylon. Exhibit 5 shows that she was wearing something nylon and it’s died green. Smokey decides to write a note saying “you will never find her”. He writes the note in black pen and he put a lot of pressure on the pen. Then Smokey decides to pick up the body and he leaves fingerprint which is a tented arch. Well he was walking the dog started barking which cause him to run and he leaves his footprint. Through exhibit 7 it is a male’s foot with a lot of pressure on ball of his foot.

Poison Analysis

For many centuries, poisoning has been a popular method of murder.   One reason is that almost any natural substance in the right dose can be poisonous, and many poisons mimic common medical diseases, leading physicians to believe a victim died of natural causes.
Toxicology is important not just for an investigation in which foul play is suspected.   It is equally essential for determining accidental deaths and suicides and even for substance abuse while on the job.  A toxicologist may be called on to test for anything from arsenic to poisoned gas to GHB to prescription drugs.


Personal Reflection

We had to determine what poison was used during each station. Take for example Cynide turns blood red when you put iron in it. that tells you that the person was poison with Cynide.

This is our group about to test if the substance is postitive for Aspirin.

Then we tested the PH of the substance to see if it was below 7

Then we add BTB to determine what substance is Aspirin

Lipstick

All students had to put on lipstick to get there print on a notecard. Then we have to label unique features of your lips. Then we had put lipstick on again put everybody lips on one sheet of paper and see if we can find ours.

Create a Profile

We used everything we learned from Hair, Fingerprint, and Handwriting Analysis to form a  scenario.  Groups were given 5 clue to use. The first clue was fingerprints and what type of print it . All pictures in post was taken by Alonzo Fullenwilder

Clue 2 was either a hair or fiber, we later found out it was colored hair.

Clue 3 was a torn note that had said "you will never find her".

Clue 4 was yet another Hair that turned out to be African-American hair.

Clue 5 was a red smudge that could of either been lipstick or blood. further testing is need
 

Witness Experiment

Picture Taken By Alonzo Fullenwilder
This test we had to remember a face of a picture. 1. Hair 2. Eyes 3. Lips 4. Nose
When we did this we had three different same sized faces and messed them up. We then used memory and the characteristics  to found the same characteristics of each face until we created the it again. One of the things that helped us find the correct pieces was the color of their skin.

Drug Analysis

Identifying drugs in the human body requires a lengthy sequence of tests and confirmations that can take weeks and even months, forensic experts said. Drug testing can be performed from small samples taken of your fingernails, saliva, or more commonly, your blood, urine, or hair. For a blood sample, a small amount of blood is taken from a vein in your arm or hand and is then sent to the laboratory for analysis. A drug test can also be used to evaluate possible accidental or intentional overdose or poisonings


Personal Reflection

For the Drug Analysis lab we had to test for Cocaine and LSD through six stations. If the substance was Cocaine the dissolved substance would turn blue and if it was LSD it would turn yellow. We also tested the PH of the drug because we need to find out if it was a base or acid.

This is the graph we made to take down the information about the six drugs we tested for LSD or Cocaine.

This is us testing the PH of the unknown substance.
