Poison Analysis
In this lab a groups of 4 students rotated around the room to various substances. we had to determine if the substances was a certain poison. The Different poison we were looking for was Household Ammonia, Aspirin, Cyanide, Iodine, Metal poisons, and suger. The indicators were placed next to each test for use of finding out which one was which. from this I learned even the simplest things in the house could be treated as poison.
Forensics Investigation
In this lab as a group of 5 students we were given a certain amount of exhibits, and were asked to analyze each individual one and put a scenario together.
The Setting: Outside, In A Field, In A Wooded Area
Lucas Moore, a depressed psychiatric patient, took his dog on walk. while walking through a wooded area he came a drug addict named Sandra O'Connor. By the evidence found we came to a conclusion with fingerprint evidence that Jet Trong had given the drug to her. When Lucas made contact with Sandra, he decided to shoot up cocaine with her. After this happened Sandra overdosed and died. Lucas panicking decided to write a suicide note so he didn't get into trouble for having drugs and Sandra's death. after finishing he left with his dog and Sandra was found 2 weeks later in active decay.
Evidence:
Possible Poison/Syringe: we were given a substance that we had to test for poison or drugs. after testing for both the substance came out positive for cocaine. We concluded that Lucas and Sandra had use the syringe to inject themselves with the cocaine.
Body/Maggots: One of our evidences was a maggot infested skull, from prior knowledge that would lead us to believe that the person had to be dead for over 2 weeks in active decay.
Footprints: There was two separate footprints found at the crime scene. Both with further analysis was found to be tennis shoes. One was of the victim and the other was a footprint leaving the scene. the victim's shoe was smaller to the footprint leaving the scene. We concluded that the victim was a women and the person who left was a male.
Hair: There was hair found at the scene near the victim's body. We had to analyze it under the microscope. when we concluded that it wasn't human we compared it with animal hair and came out to be dog hair.
Fiber: A small piece of fiber was recovered from the scene and after analysis was completed, we found it to be wool. This fiber tends to be warm so they make coats out of them. Which brings us to a conclusion that it was cold or night time.
Ripped Note: Pieces of ripped paper were found at the scene. When we put together it said "Please forgive me! I love you all." The way this note was wrote it looked like a suicide. The thing that gave it up to not be Sandra's note was the handwriting. We looked at our suspects list and found Lucas Moore's handwriting to match. So as a group we came to the conclusion that Lucas had faked Sandra's suicide note.
Fingerprints: First print would be a plain arch which only matched one suspect which was Lucas Moore, this helped us decrease the list of suspect. second print would be a double loop which brought us to the drug dealer Jet Trong, who gave Sandra the drugs. Third and last print would be a ulnar loop which brought us to another suspect Sandra O'Connor the drug addict who ended up being the dead body found at the crime scene.

Create Profile
In this experiment we used everything we learned from Hair, Fingerprint, and Handwriting Analysis to form a scenario and a suspect. Each group was given 5 clue to use. The first clue was fingerprints and we had to determine what hand and what type of print it was. It was from the right hand.

Clue 2 was either a hair or fiber, after analyzing it we concluded that it was colored hair.
Clue 3 was a torn note that had said "you will never find her".
Clue 4 was yet another Hair or Fiber clue which turned out to be African-American hair.
Clue 5 was a red smudge that could of either been lipstick or blood. (further testing required to find out.)
This lab helped us use problem-solving to create a educated assumption on who was there and what happened.
