Alright folks, I have some old college buddies who work for a certain network in Bristol. They tell me they don't know a thing personally, but the cafeteria lady on the network's campus says Mullen gave her a big hug and a tearful goodbye. Turns out, she's been sneaking him bourbon at lunch, so they're tight.
Anyway, he told her he's leaving to be an offensive coordinator. He wouldn't tell her where, but on the way out of the cafeteria he went to the fresh fruit, grabbed an orange and tossed it to her with a wink.
And that was the last time anyone saw Dan Mullen in Bristol before he got into his Enterprise rental car and drove towards upstate New York.
