Crime Scene Investigation: Case Closed?

We believed that Jet Trong was a drug dealer for Sandra O’Connor (explains his fingerprint, which would have been found on a bag of drugs), who was a homeless drug addict. The sneakers were found on her, because she needed good outdoor shoes for living in the woods. Lucas Moore was walking his dog (explains the dog hair found on scene) out in a wooded area & came across Sandra doing cocaine (the liquid tested positive for cocaine) so he decided to inject with her (explains the syringe/needle.) Sandra overdosed on the cocaine & dies right on the scene. Lucas was afraid of being caught with cocaine so he wrote a fake suicide note pretending to be Sandra, saying “Please forgive me! I love you all.” And walked away (explains shoe walking away from crime scene) The body was left for so long that it started to decay & when someone found it, it was already infested with maggots. 

The breaking point of our investigation was when we tested the liquid to be cocaine positive, because it gave good reason for Jet & Sandra to be involved. Sandra was a drug addict after all, which explains the OD!

Crime Scene Investigation: Suspects

There were 10 suspects:

Of these 10, 5 were relevant to our specific case & 1 animal was relevant to our case:

Same handwriting from note!

Same fingerprint as on scene!

Same fingerprint as on scene/drugs?

Same fingerprint as on scene!

Same fingerprint as on scene/drugs?

Dog hair found on scene!

Crime Scene Investigation: Intro

For the final project of the forensics unit, we were given a "crime scene" with different evidences, clues, & suspects of a crime. Our job was to test & analyze the different things that were given to us & create a story of what happened, who died, & who was the killer. Each exhibit given to us was something to help us solve the case; we had 11 exhibits to work with & 10 suspects, with 2 animals.

Testing: Drug Analysis

For this experiment, we were given simulated drugs & three different drug reagent testers for cocaine, LDS & meth. Six “drugs” were set up & in groups of four, we tested them with the reagents for LSD, meth or cocaine. We also tested the pH of each drug for further analysis.

Drug 1- cocaine positive & LSD negative with pH of 6

Drug 2- cocaine positive & LSD negative with pH of 9

Drug 3- cocaine negative & LSD positive with pH of 3

Drug 4- cocaine positive & LSD negative with pH of 7

Drug 5- cocaine negative & LSD positive with pH of 6

Drug 6- cocaine negative & LSD positive with pH of 5

Testing: Footprinting

In this experiment, each group of 4 went outside & collected a bin full of dirt. (Near a wetland) Each person stepped one of their shoes into the dirt, laying a footprint. We analyzed each person's footprint, recording important characteristics, the temperature outside, the wind strength, the substance it was found in ect. On each sheet, is a separate person's footprint along with the analysis that goes with that footprint.

Testing: Creating a Profile

For this class experiment, each person (group of four) cut out a face from  a magazine, of relatively the same size. We cut the eyes, nose, lips & hair apart from each face then scrambled them. We had to remake the original faces with the different features. This taught us that each individual feature of a person's face is important in witnessing a crime.
