Purgatory on the 2nd floor

Just minutes ago "Hell on the 7th Floor" made a return to Wurster Library. I have the culprit narrowed down to one of two individuals.

Suspect A: A rather pasty, disaffected-looking white boy, about 23-24, who arrived about the time the library appeared on itunes.
Suspect B: A guy sitting across from me with an HP Pavillion (poor guy). He's wearing sort of heavy soled shoes, a knit cap pulled down over his furrowed brow, and an oversized orange t-shirt that goes down to his knees.

More from "Hell's" library:

1. Godflesh
2. Hellacopters
3. Gang Green
4. Poison Idea
5. Pig Destroyer (I guess it is Passover, but...)
6. Stiff Little Fingers*
7. Tomahawk
8. Discharge
9. Carcass
10. Backyard Babies
11. Johnny Cash

I wonder where this guy hangs out when he's not at the libary? I remain intrigued.

*I suggest this band change its name to "Stiff Little Fingerz". The "z" adds a nice element of slasher-inspired flair.
