Yesterday morning Mrs. Riedell, 8th grade Science teacher, opened her classroom at 7:30 am to find it had been vandalized during the night. A lab cabinet containing chemicals had the broken into and chemicals had been spilled.

A trail of white powder was found in the hallway leading toward the high school. A ransom note was left behind by the perpetrator or perpetrators.  

Fingerprints were discovered at the crime scene that did not belong to Mrs. Riedell or any of her 8th grade students.  A list of suspects has been identified. Lockers were searched and samples of white powder and markers were seized from suspect's lockers. 

Your mission is to:
1. Determine the identity of the white powders found in the suspects' lockers
         and compare to the crime scene.
2.  Compare fingerprints from the 5 suspects to those found at the crime
        scene.
3.  Analyze the marker used to write the ransom note and compare to
        markers found in the suspects' lockers.
4.  Determine who you think is guilty of this crime.
