1. STATION 1: TORN T-SHIRT
Two pieces of cloth are torn out. One piece can be individualized by the shape, the other cannot. Question: Does color make a difference?

2. STATION 2: Glass fragments
Since the glass parts are so small, can you even tell all the pieces were there? This is class evidence.
STATION 3: Glass fragments
Now the glass parts are larger and some pieces can fit together as pieces of a jigsaw, and even some of the words on the bottle can be pieced together. This is individualized evidence.

3. Station 4: the note
The note cannot be individualized unless there is a tear pattern or writing indention pattern, In this case, the writing left indentions in the pad pages below. This is individualized evidence. Further analysis could be done on the paper quality, ink analysis, and handwriting analysis.

4. Station 5: can of soda
If a tear pattern can be matched form the tab to the can, then it is individual evidence. However, a lot of samples would have to be investigated to determine the odds of a unique tear pattern; this is highly improbable, therefore, this is class evidence.

5. Station 6: muddy shoeprint
The shoe can be classified as individual evidence because of the wear pattern from the sole of the shoe. Also, if further analysis is done on the soil, it can be possible to tie the shoe to the scene if the soil samples matched.
Station 7: the newspaper
The newspaper sections are class evidence because there is no way to tell if section A and section B came from the same source unless of the crease pattern or paper tear pattern. Plus, they were two different dates!

6. Station 8: mysterious powder
Although the two powders look similar, there is no way to tell if the both are related, unless chemical composition tests are performed. This is class evidence.
Station 9: cut papers
Cut papers would be very difficult to individualize unless unique scissors were used, therefore, these are class.

7. Station 11: The matchbook
Station 10: torn papers
Torn papers could be pieced together like a puzzle; therefore, they are individualized evidence.
Station 11: The matchbook
Without the matchbook, the single match would be class. But by comparing the match’s characteristics (such as dimensions, color, head, composition, tear pattern, and the like) with those from the suspect’s matchbook and perhaps a dozen randomly collected matchbooks, it could be individualized.

8. Station 12: The duct tape roll
The cut specimen of duct tape is classified as class when by itself, but if the roll is recovered, then the tear pattern from the piece and the roll could be linked together and individualized.
Station 13: latex gloves
There is no way to tell that the glove came from the box. There are no distinguishing marks that can make the evidence unique.

9. Station 14: bullets
Bullets can be individualized by the striations on the outside and the spent shell casings, to some degree, can be individualized by the firing pin marks.
