I worked at Blackjack Pizza.
I remember Eric brought a "pipe bomb" inside the joint, one time. He immediately took it outside for "removal"
And yes, I would see Eric, Dylan, Nate Dykeman and Chris Morris wear trenchcoats.
Chris Morris to me, seemed to be most violent of the four and I would overhear him, talk about "pipe bombs" a few times.
After work, I remember I walked past Matthew Paul Jackson.
He vaguely said to me that "one of them" thought about, "having us come together"
Making a bomb and possibly blow up the Kilt and Candle Bar.
It's located near Platte Canyon High School and Bowles Avenue.
