A black lab named "Pep" was sentenced to life without parole by Pennsylvania Governor Gifford Pinchot for reportedly killing his wife's favorite cat.
He even got a mugshot:
While that sounds horrible, legend has it the dog was actually put in the prison to act a morale booster for the prisoners. Basically, Pep didn't kill any cats. He was treasured by the inmates for over a decade.
Everyone knows black labs wouldn't do that anyway!
