I suspect it was the hobby of "making fireworks" that did him in.
Nah. Wrong. It was the scumbag Joe Scott who finked on him that did him in. And before that could happen, he made the mistake of trusting "Finky" Joe. That combination "did him in."
I 'd hazard that "Finky" Joe Scott should be thinking about relocating before this dude gets out of stir. He'll probably spend the next 21 months very carefully planning how to express his displeasure to Mr. Finky without it ever being traced back to him.
Human nature being what it is, and all.
N'yuk, n'yuk, n'yuk.
