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.

Lifting fingerprints

These lifted fingerprints were done by the use of powder. There were two types of powder that was used. For the prints done on the black sheet crushed chalk was used. A fingerprint was placed on a dark surface and then the chalk was applied to the fingerprint with a brush. Then the tape was taped to the black sheet. For the print done on the white sheet crushed charcoal was used. A fingerprint was placed on glass and then charcoal was applied with a brush. Then taped was applied to the glass to get the the print then taped down on the white sheet of paper. This process was difficult to complete because the powder sometimes wouldn't stick and it was hard to get the print.

Hair activity

In this activity there were different types of hair and fibers. There were hair from African Americans, Caucasians, Asians, Mexicans, a dog, and a cat.We had to analyze these hairs and fibers under a microscope and observe the texture and color of the hair to see the differences between the types of hair. The same with the fiber we observed them under a microscope to look at texture and color. These activity allowed for me to see the difference between hair of different ethnic groups and I learned they do not look similar.

Poison activity

 

In this activity we tested various liquids to see if they contained any poisons.

Poison- A substance that, when introduced into or absorbed by a living organism, causes death or injury, esp. one that kills by rapid action.

Common poison sources:
Carbon monoxide which is a deadly gas which is odorless. 
Food poisoning which is caused by bacteria in foods. 
Household products are poisonous if eaten or drunk. 
Lead in paint is dangerous
Plants

How do crimes labs handle poison cases? 
They are taken to forensic toxicologists who then analyze biological specimens and then determine what substances were ingested, along with the amount of it.


What are some signs of poisoning?

• enlarge the pupils
  
• excessive drooling or dry in the mouth and skin.
  
• Some speed the heart, while others slow the heart.
  
• Some increase the breathing rate, while others slow it.
  
• Some cause pain, while others are painless.
  
• Some cause hyperactivity, while others cause drowsiness. 

Modus Operandi

Modus Operandi is a Latin phrase, translated as "mode of operation". In this experiment we had to put down our fingerprints from both hands and describe them as ulnar, loop, whorl, or an arch. We then had to make up an alias name and trade our papers with the fingerprints with someone else and describe their finger prints. What I learned from this experiment is that I have a lot of ulnar loops.

Handwriting Analysis

In this experiment we all had to try and forge someones handwriting by tracing and free handing it. Forging someone handwriting by free handing is very difficult and it easy to tell that it was forged. Forging by tracing is more easy to do but when tracing someones else handwriting your copy tends to be more darker then theirs. Also we had to write a check and rip it up and trade with another person to see if they can tell who's handwriting it is. What i learned from this experiment is that i have a very difficult handwriting that no one can free hand or trace.

Handwriting

History of Handwriting Analysis

In 1915, Bunker made his unique discovery. He recognized that each of his students formed shorthand strokes in a unique manner. He suddenly and clearly realized that it was not the letter which had a trait meaning but the strokes – the shape of the formations within the letter. 

After traveling thousands of miles, and interviewing thousands of people and examining more than half a million handwriting specimens in his lifetime, the copyrighted American System of handwriting analysis – Graphoanalysis was born.

Handwriting Characteristics:

§  Line quality.

Ø  Are the pen marks smooth and free flowing or shaky and wavering?

§  Spacing of words and letters.

Ø  What is it the spacing between letters and words? Is it consistent?

§  Ratio of the relative height, width and size of letters.  

Ø  What is the ratio? Is it consistent?

§  Pen lifts and separations.

Ø  Does the person stop to form new letters and begin words?

§  Connecting strokes.

Ø  Are capitals connected to lowercase letters and are there connecting strokes between letters and words?

§  Beginning and ending strokes.

Ø  Are these straight, curled, long or short, an upstroke or a down stroke?

§  Unusual letter formation.

Ø  Are there any unusually formed letters such as backward, letters with a tail, or unusual capitals?

§  Shading or pen pressure.

Ø  Is the pen pressure on the upward or the downward strokes?

§  Slant.

Ø  Is slant left or right or straight up and down? Is there consistency between the slants of  letters

§  Baseline Habits

Ø  Is the writing above or below a line?

§  Flourishes and embellishments.

Ø  Are Their any? If so what are they?

§  Diacritic placement.

Ø  How is the t’s crossed? Look at the dotting of the i’s, j’s. For example are the dots to the right or left of the letter?

The Lindbergh Kidnapping: Charles Augustus Lindbergh, Jr., 20-month-old son of the famous aviator and Anne Morrow Lindbergh, was kidnapped about 9:00 p.m., on March 1, 1932, from the nursery on the second floor of the Lindbergh home near Hopewell, New Jersey. The child's absence was discovered and reported to his parents, who were then at home, at approximately 10:00 p.m. by the child's nurse, Betty Gow. A search of the premises was immediately made and a ransom note demanding $50,000 was found on the nursery window sill. After the Hopewell police were notified, the report was telephoned to the New Jersey State Police, who assumed charge of the investigation. This case was based on handwriting there were three ransom notes written.http://www.fbi.gov/about-us/history/famous-cases/the-lindbergh-kidnapping. go to this site and learn more.
