Don't get too excited. I don't want to jinx this.
According to CBS, Mark Lee Krangle was taken into custody. I'm not sure if the WPXI story refers to the Krangle arrest. Now it seems that way. Disappointing, because I'm 99% sure Krangle isn't the one making the bomb threats.
But still, it's encouraging we've had "only" five threats in the past two days.
Also: I added a Twitter feed. All credit goes to the gentleman running it, he's insanely on top of things. Probably the best journalist working on this right now.
