Who dunnit? Crime scene

Last week I was doing a crime scene with a group. We had a crime scene bag containing, a fibre sample, white powder from the crime scene, fingerprints, and a note. We had a booklet containing suspects and police information. We had to idenitfy what fingerprint they had,what fibre they were wearing and if they had to do anything with powders, and what their handwriting looked like. We had four suspects; Cecil, Chole, Connor and Carrie. We decided between 2 suspects; Chole and Cecil.
We decided it was Chole because, the white powder provided in the crime scene bag had a similar effect compared to washing powder that was in the experiment box.

The booklet containing police information on the suspects said that Chole was a cleaner, so it made sense that a cleaner would use washing powder. The fibre sample provided in the crime scene bag was like the sheepskin, also provided in the experiment box. The fingerprint provided in the crime scene bag was a arch finger print, in the booklet that contained the police information on the suspects, Chole had the same fingerprint because we used a magnifying glass to zoom in on the fingerprint. The handwriting was the exact same, because once agaain, the information provided in the booklet and the magnifying glass backed up our hypothesis.

I enjoyed doing the crime scene with our group. I especially enjoyed the way we worked together as detectives to solve the crime scene. 
I didn't really find anything tricky or hard. Just that the class was a bit noisy. Because of that, I couldn't really hear my group that well.

Do you think that you can solve a crime scene? If so, what do you think your chances are in solving a crime scene similar to what my class did? Please tell me in the comments!
