Murder Mystery Project
In this project we were grouped up and tasked with a scenario where a murder was committed and our group, using the evidence left on the scene of the crime, had to discover who murdered the man name Captain Cornball.
How did we do it?/Evidence we used.DNA and DNA fingerprint:
Norma Nanny’s DNA sequence matches one of the given 2 off of the crime scene and the other matches Captain Cornball. Also Norma Nanny’s DNA fingerprint matches one of the 2 samples off the crime scene while Captain Corball's matches the other again. Sam Stubs’ DNA fingerprint also matches but one of the 2 samples has to be Captain Corball's since he was murdered. There are no other DNA fingerprint matches except for Cornball and Norma, but there are sequence matches. Theresa Thyme and Fred Flintstone's sequences match but they haven’t been matched up with any DNA fingerprints, fingerprints, or ink match so it is highly unlikely they committed the crime. Blood Type and Chromatography: We believe Norma Nanny killed Captain Cornball. The O blood found on the scene is Captain Cornballs because there was only A and O blood found meaning that one has to be the Captain’s. That eliminates Fred Fleck Stone, because he has O blood type and did not have an ink match, DNA fingerprints, or regular fingerprints. Sam Stub’s is as well O type and his ink matched, but it cannot be him because one of the blood types has to be Captain Cornballs. Theresa Thyme and Greg Glendora has type A blood which is the other found on Captain Cornball, but their ink, DNA fingerprints, and regular fingerprints were not a match. That leaves Norma Nanny as the only one left who’s blood type is A and her ink was a match.This means that Norma Nanny must be the one who killed Captain Cornball. Glass fingerprint: We have cause to believe that the fingerprint which lead to Glen Glendora is meaningless. A murderer with any knowledge of how to commit the felony would make it a point to leave little to no evidence. The glass was accessible to everyone and could have had any of the 6 individuals fingerprints. When the sky darkened there could of been panic and any of the 6 could’ve knocked the glass and broken it. The glass had nothing to do with the murder and it is more likely the murderer left no print maybe due to wearing gloves. Blood Type: We found the blood types of all people on the crime scene by taking blood samples and seeing if they clotted to anti-a antibodies, anti-b antibodies, or neither. We ended up finding that Cornball, Stubs, and Fred were O type. Also that Theresa, Norma, and Glen were A type. Chromatography: There was a letter that had to ink of the killer on it. There were 3 choices of pens. We put a dot from each pen on slits of chromatography paper and put them in a beaker with concentrated alcohol. The alcohol would be absorbed into the paper going through the ink, causing it to bleed. After chromatography each ink releases a different pattern. One released red and yellow, black out of another, and nothing out of the third. The Crayola pen that had red and yellow pulled from its ink was a match. Norma Nanny and Sam Stubs both owned the Crayola pen, but Sam Stub’s blood type is O which makes him no longer a suspect. DNA fingerprint: Using a DNA fingerprint from the crime scene we were able to take a sample from each of the six individuals and find a match. To find this match we took samples of DNA from the possible convicts and injected them into an agar gels. We then hooked the agar gels up to a power supply to run electricity through the samples. This created different colors based on the different DNA samples. |
Two Thumbs Up/ I Wonder ifThis project to be proved to be annoying at sometimes, but fun and interesting at others. I liked the process of looking through the characters motives and doing the pedigrees. I wonder if we should have had some much stuff to do.

Arrest WarrantArrest Warrant First Degree for Norma Nanny:
This affidavit states that there is probable cause for arrest of Norma Nanny. With matches of DNA fingerprint leading to her from blood type, ink match, DNA sequence, and chromosomal disorder. The further evidence may be noted and used in trial. What did we learn about?We learned human genetics and how offspring of people with disorders do not always have to have the same disorders, but have a decent chance to have the same disorder as their parents
Also we learned about chromosomal abnormalties and how having one extra chromosome can make such a huge difference in somone's life. Another thing that we learned was about DNA and how to work more efficiently then the last lab because I made sure everyone was on task and tried to investigate the material as best as I could. |
