Transcript of CSI Presentation

Platt CSI
By: Jacque Velasco, Katie Cobb and Saunders Carlson.
Hand Writing
Blood types
Finger Prints
Based on the blood types I collected from teachers and staff, and the blood that was taken from the crime scene, we found a lot of matches of teachers with O+ blood. The blood types we found on the crime scene were tested as O+ and B+. To test the blood found in the crime scene, we put 5 drops of Antigone A, Antigone B, and Rh in the blood from the crime scene. Our suspect has O+ blood.
Based on the evidence we found from our handwriting samples and the note from the murderer at the crime scene, we were able to analyze this note and compare it to our handwriting samples. Looking at the handwriting samples and the note we found a person who's hand writing just about matches. Some key letters we looked at were these letters y, a, and .
The Murderer
Based on all of the evidence that this CSI team collected, we have caught Mrs. Z red handed.
Based on the results of the finger prints I collected from teachers and staff, we found a match with a finger print from the beaker and our prime suspects. Their right thumb matched one of the prints from the beaker and their index finger matched the other. When comparing the suspect's finger prints to the killer's, we looked at things like if there were any ridge endings, whorls, loops, deltas, etc. In the next slide you will see images of the suspect's finger prints and the actual finger prints of the murderer that came from the crime scene.

The size of the writing was clear and big. When we went and got a handwriting sample from

Suspect's thumb
Killer's thumb
our suspect, we were able to pick out these same things. You will see their handwriting and the killer's handwriting in the next slide.
Based on the evidence found we were able to figure out who the killer is. From the clue "don't judge a book by its cover." We found book number 88 in the library. We scanned the QR code in the book and a video was what it gave us. The video led us to locker number 507. Which was also a room number. It was the room number of our prime suspect.
Favorite Food
Room Number
While the crime scene was still up we figured out where the arrow on the yard stick was pointing. It was pointing on to a Boogle project. In the key of the Boogle project there was a QR code which showed the killer's favorite food. Which is chocolate. When we asked our suspect their favorite food is she told us, chocolate and blueberries.
The Planner
We found many different things in the planner, but one that stood out to us was the on page the word November was circled. Which made us believe that the killers birthday must be in November. Using all the other evidence we had, we decided to ask our suspect when their birthday is. They told us that their birthday was November 22.
Other Evidence Conclusion
Blood Conclusion
Finger print conclusion
The most common blood type is O+, so that made it quite difficult for us to narrow it down to one person who could be the murderer. Our suspect does in fact have O+ blood. Also when we put our evidence together it made it easier to decide who our final suspect was going to be.
Handwriting Conclusion

Based on the evidence found we believe we know who the killer is.
Based on the evidence that we collected on handwriting when we went to adults around the school. There was a note at the crime scene that was a note from the murderer, we studied the handwriting and found that our suspect's handwriting matched the handwriting of the murderer. This was because of the a's, y's and the style of the handwriting.

Group Conclusion
Based on the results of this experiment, we used the scientific method to convict the murderer who killed Jonah Rondash. To figure this out we found collected finger prints, hand writing samples, and blood samples. Using our evidence, we were able to decide who we thought was the killer.
Blood Tray
To find the finger prints of the killer, we had to go to a lot of teachers and take their finger prints. When we had a lot of evidence against somebody who we didn't have finger prints for, we decided to take theirs. Luckily for us they matched, like you saw in previous slides.
On the glass we found the number 7 and the letter G. We also found the numbers 20 and 26. We figured out that 7=G. G is the 7th letter in alphabet. Then we figured out what the 20th and 26th letter of the alphabet is.
By Saunders Carlson
At first we didn't know what TZ meant, but then when we looked at our victims initials they happed to be TZ.
