I think David is the person who had murderd Susan because there was a red blue and white lots wich we had discovered it had matched David . Also at the scene there was ink that had not changed colour which surprisingly was the marker David had used in conclusion we believe David had committed the crime

We think that it is David because his fingerprint was found at the scene of the crime and it has been found that also the paper that has not been spread the marker that was the favourite of David.
It isn’t anybody else because as we have seen the fingerprint already it wouldn’t be anybody else

  This doesn’t quite make sense, please write your reasons again.

  I think that it was David because the cloths he was wearing on were identical to the ones that got shown to all the tables.another reason why I thought it was David is because his favourite 🖊️ was the only mark that didn’t move.

We think it was David committed the crime because
David’s fingerprint matched the print found at the crime scene
Exhibition Bs fabric was identical to the fabric on David’s shirt
Davids favourite pen is a whiteboard marker and at the crime scene there was ink and water but the ink did not spread when we experimented the whiteboard marker did not spread

Me and my team believe that the suspect is David as his fingerprint is at the crime scene and his shirt was torn and left at the crime scene and he has been jealous of Susan and was annoyed that she had been successful.

Haroon, Tyson, Ismael, Jensen.

We believe that David committed the murder.
We think this because his fingerprint matched the one at the crime scene. In addition his pen ink did not spread when exposed to water so we know that David committed the murder.

Something that confused us was that Tom’s ink had blood or ketchup stains on it which was strange but we have concluded that the murder was not committed by Tom but by David himself!

I know that David is the murderer because we gathered evidence such as:
The fingerprints on the crime scene was the same as David’s.
Also the evidence on exhibit b showcased David’s shirt but all the other shirts that were shown were not exactly the same but David’s shirt was exactly the same.
Lastly the chromatography showed that David’s pen did not spread just like in the crime scene.
To conclude David is the murderer.
