The Murder:
Carelton Comet was brutally murdered on October 16th, 2016 at 7:35 PM, following a 30 minute picnic with five individuals: Theresa Terra, Fred Flimmer, Glen Glee, Sam Sophomore, Nancy Normal.
THE MYstery:
Who did it? Why? How? Our job was to find out. We were given several pieces of evidence and we had to determine who the killer was and their motives.
The EVIDENCE:
A: The Murder Weapon (Knife)
- A fingerprint found on the knife matched the fingerprint of Nancy Normal. C: Fibers Found on the Murder Weapon -The fibers were found to be human hairs. E: DNA Fingerprinting - DNA Matched Nancy Nomal |
B: Blood Found on the Knife
- Type A blood was found on the knife and matched with the blood of Theresa Terra, Glen Glee and Nancy Normal. D: Threatening Note Found at the Crime Scene - The ink found at the crime scene matched Nancy Normal's pen. |
Our Pedigree:
A pedigree is a representation of one's family history. It shows diseases, deaths, relationships, etc. In this case, it shows the connection between our suspects and what diseases they had.
CONTENT:
Forensic Science: the application of science to criminal and civil laws during a crime investigation. The solving of Carlton Comet's killer used forensic science.
Karyotypes: the number and visual appearance of the chromosomes in an organism. Each suspect's karyotypes were recorded and the chromosomal disorders were studied off each person.
Chromatography: using an alcohol to determine the Rf factor of an ink source. We used this to determine that the pen belonged to Nancy Normal.
Co dominant: two fully expressed alleles in a gene pair. Striped fur is co dominant in animals.
Incomplete dominance: situation in which one allele is not completely dominant over the other. Animals with a mix of black and white making a grey colored fur.
Recessive: the "weaker" trait that needs two of the same trait to show. Blue eyes are recessive traits.
Dominant: the main part of a trait that controls or overrides other genes- if it is preset then the trait is expressed. Brown eyes are dominant over green and blue.
Gene: sequences of DNA that codes for a protein that determines a trait. Your genes can code for light brown hair or dark brown hair based off your
genetics.
Alleles: one of a number of different forms of a gene. Alleles are what determine your traits.
Probability: likelihood that a particular event will occur. If both your parents have curly hair, the probability of having straight hair is less likely.
DNA Fingerprinting: A technique used to find the links of DNA that are based off size, and match it with family members or crime scenes. This was one process we used to find the fingerprinting on crime scene 1 and 2.

OUR VERDICT: NANCY WAS THE KILLER
The overwhelming amount of evidence suggests that Nancy Normal was the killer. The vast majority of the results showed Nancy Normal as the match. Therefore we can charge her with 1st degree murder, as it is evident that she planned her murder beforehand based on her motives, which will be discussed next.
NANCy Normal's Motives:
- Some of theNancy’s family members have been killed by Comet
- The Nancy’s Cousin Nadia was kidnapped and murdered when Nadia was three years old
- The Nancy’s Father, Tony Sophomore, was killed in a “bizarre gardening accident.” It’s possible that Comet was involved in this accident
- The Nancy’s Cousin Nadia was kidnapped and murdered when Nadia was three years old
- Nancy “adores” Fred Flimmer, who was “embarrassed by his father’s, Thomas Sandstone’s, actions when he killed Fred’s aunt and sister. Nancy may have wanted to avenge them to prove herself to Fred, etc.
REFECTION:
Through the course of this project, we had successes and failures, and we learned from both. For example, on one of our last days, I was sick and had to skip school. I relied on my group members to get the job done, and we finished it in time. We also found success in our clearness of evidence and our presentation, which got the judges to give us a warrant. However, things like our presentation skills didn't work out so well. At the end of it all, I think I learned how to work better in groups and how to improve my skills whether we succeeded or failed.
