A mom who, during the winter months, wears a hoodie and sunglasses while dropping children off at school. The look is eerily reminiscent of the police suspect sketch of the infamous serial killer Unibomber, AKA Ted Kaczynski, who targeted universities and airlines with homemade bombs sent through the mail.

Cletus was dropped off at school by an older mystery woman in a hoodie and sunglasses. She was even sporting a fuzzy newborn baby 70s porno stache. I think it was his Unimomer.
